The term " comprising " and " having " occurred in present specification, claims and accompanying drawing and their any changes Shape, it is intended that cover non-exclusive including.For example contain the process of series of steps or unit, method, system, product or Equipment is not defined in the step of listing or unit, but alternatively also includes the step of not listing or unit, or alternatively Also include other steps intrinsic for these processes, method, product or equipment or unit.In addition term " first ", " second " " 3rd " etc. is, for distinguishing different objects, and to be not intended to describe specific order.

First illustration explanation is carried out to some relational languages below.

Referring to Fig. 1-a~Fig. 1-b, stop line and road that the embodiment of the present application is arranged on the Parking Entrance of grade crossing The relative position of mouth safety line can be as shown in Fig. 1-a or Fig. 1-b citings.Wherein, grade crossing shown in Fig. 1-a is additionally provided with Crossing, and grade crossing shown in Fig. 1-b is not provided with crossing.Certainly be also likely to be grade crossing its Crossing is provided between middle part divided lane and crossing (this scene is not shown in Fig. 1-a and Fig. 1-b).Fig. 1-a~Fig. 1-b In be that by taking cruciform plan intersection as an example, but grade crossing is also also possible to be T-shaped grade crossing Or other shapes of grade crossing.

Wherein, the Parking Entrance of grade crossing can also be referred to as entrance driveway.One Parking Entrance of grade crossing One or more entrance lane is may include, entrance lane is alternatively referred to as import track.The exit ramp of grade crossing can also Referred to as downstream road.One exit ramp of grade crossing may include one or more exit lane, and exit lane also can claim For downstream track.In the relevant drawings of the embodiment of the present application mainly so that Parking Entrance is located at corresponding exit ramp right side as an example, and Some national Parking Entrances are also likely to be positioned at the left side of corresponding exit ramp, for such situation can the rest may be inferred.

Wherein, if a Parking Entrance includes a plurality of entrance lane, then the guiding of this plurality of entrance lane may identical, portion Split-phase is same or different.The guiding of entrance lane can be divided into left-hand rotation, keep straight on, turns right and turn around.For example, certain Parking Entrance X Including 6 entrance lanes, it is assumed that wherein 2 entrance lanes of above-mentioned 6 entrance lanes be directed to turn left, then this two enter Mouth track can be referred to as the left-hand rotation entrance lane of Parking Entrance X, and left-hand rotation entrance lane can abbreviation left turn lane.Assume that above-mentioned 6 enter Other 3 entrance lanes in mouthful track are directed to straight trip, then this 3 entrance lanes can be referred to as the straight trip of Parking Entrance X Entrance lane, straight trip entrance lane can abbreviation Through Lane.Assume 1 entrance lane of residue in above-mentioned 6 entrance lanes It is directed to turn right, then this 1 entrance lane can be referred to as the right-hand rotation entrance lane of Parking Entrance X, right-hand rotation entrance lane can be referred to as Right-turn lane, by that analogy.

For example, a cruciform plan intersection (such as shown in Fig. 1-a~Fig. 1-b citings) typically may include 4 Bar Parking Entrance and 4 exit ramps, every Parking Entrance may include one or more entrance lane, every exit ramp may include one or A plurality of exit lane.T-shaped grade crossing generally comprises 3 Parking Entrances and 3 exit ramps, and every Parking Entrance may include one Bar or a plurality of entrance lane, every exit ramp may include one or more exit lane.Certainly some grade crossings enter The quantity of mouthful road and exit ramp is likely to unequal, and such as certain cruciform plan intersection is likely to only include 3 Parking Entrances With 4 exit ramps.

In some cases, the guiding of some entrance lanes possibly transformable (i.e. revocable), such as at some Period entrance lane is left turn lane, and it may be Through Lane in other periods, and this track can be referred to as to lead To changeable driveway, other analogues are by that analogy.

In some cases, the guiding of some entrance lanes is probably multiple, and for example certain entrance lane both can be straight traffic Road, while it can yet be right-turn lane.The concrete such as rightmost entrance lane of certain Parking Entrance may both be Through Lane, together When be also right-turn lane, and this track can be referred to as multi-guide track or compound direction track, and other analogues can be with This analogizes.

The travel direction in track is usually fixed, but in some cases, the travel direction in some tracks is also likely to be Variable (i.e. revocable), such as tide track are exactly a kind of variable track of typical travel direction, and travel direction is variable The track of change is also referred to as travel direction changeable driveway.The travel direction in track can be for example east orientation (i.e. eastbound), west to (i.e. Head west), south orientation (i.e. southern row), north orientation (i.e. southern row) etc..The travel direction of such as certain Parking Entrance is east orientation, then in the Parking Entrance Left turn lane be also referred to as east orientation left turn lane, east orientation left turn lane is also referred to as eastbound left turn lane under some scenes, should Through Lane in Parking Entrance is also referred to as east orientation Through Lane, and in the case where there is some scenes, east orientation Through Lane is also referred to as east Row Through Lane, the rest may be inferred.

In the embodiment of the present application, the crossing safety line in the track (such as entrance lane, exit lane) of grade crossing is Refer to lane line that is adjacent with crossing or crossing, or refer to lane line that is adjacent with crossing or crossing.Wherein, The stop line of entrance lane can be arranged on the safe line position in crossing of the entrance lane.Or relative to the traveling of entrance lane Direction, the stop line of the entrance lane may also be arranged on after the crossing safety line of the entrance lane.In the conventional technology, entrance The stop line in track is typically all the safe line position in crossing for being arranged on the entrance lane, will stop line and crossing safety line Unite two into one on locus.And in the embodiment of the present application, mainly with relative to the travel direction of entrance lane, the entrance car The stop line in road be arranged on after the crossing safety line of the entrance lane as a example by inquiring into, that is to say, that the embodiment of the present application scheme Breach the inertial thinking of the safe line position in the crossing that stop line is arranged on into entrance lane, it is audacious by entrance lane Stop line and crossing safety line are separated on locus, the crossing safety of the stop line of entrance lane relative to the entrance lane Move after line, and then define brand-new stop line layout type.Wherein, the set location of the stop line of entrance lane can be phase To fixed, i.e. the spacing between the crossing safety line and the stop line of the entrance lane of entrance lane can be relatively fixed, when So, it is also possible to the factor such as need to carry out adaptability to the set location of the stop line of entrance lane based on environmental factor and scene Adjustment.

Vehicle on each track of grade crossing can be allowed to pass through under the control of traffic lights and (permit Perhaps passing through can referred to as permit row) or no through traffic (no through traffic can be referred to as forbidden) or warning is passed through, and (warning is current to be may be simply referred to as Alert row), in general, the vehicle that the corresponding traffic lights of certain entrance lane can control on the entrance lane is allowed or alert row Or it is forbidden.Wherein, control the phase place that vehicle on the entrance lane lets pass can be referred to as the entrance lane current phase place it is (logical Line phase is alternatively referred to as clearance phase place or fair line phase), because corresponding traffic lights send optical signal in conventional art Color is green during current phase place, therefore, in the conventional technology, current phase place is also commonly referred to as green light phase place, this Shen Please be in the technical scheme of embodiment, the color that corresponding traffic lights send optical signal during current phase place is not limited to green Color, and can be expanded to can be used to indicate that any solid color or several colors that allow vehicle pass-through are combined, phase place of passing through It is the optional enforcement of one kind in green simply the embodiment of the present application that period corresponding traffic lights send the color of optical signal Mode.The phase place of the Pedestrian Zone At any time on control entrance lane can then be referred to as the forbidden phase place of the entrance lane, in tradition In technology, because the color that corresponding traffic lights send optical signal is red, therefore conventional art during forbidden phase place In forbidden phase place be typically also referred to as red light phase place, in the embodiment of the present application during forbidden phase place corresponding traffic lights institute The color for sending optical signal is not limited to redness, and can be expanded any single for can be used to indicate that no thoroughfare for vehicles Color or several colors are combined, and the color that corresponding traffic lights send optical signal during forbidden phase place is red simply this Shen A kind of optional embodiment that please be in embodiment.Similar, controlling the phase place of the vehicle police's row on entrance lane can be referred to as For the alert line phase (alert line phase can also claim transition phase place) of the entrance lane, due to corresponding traffic lights institute in conventional art Alert line phase is typically also referred to as amber light during the color for sending optical signal is yellow, therefore conventional art during alert line phase Phase place, the color that corresponding traffic lights send optical signal during alert line phase in the embodiment of the present application is not limited to Huang Color, and can be combined by any solid color or color expanded to can be used to indicate that warning vehicle pass-through, alert line phase It is a kind of optional embodiment party in the embodiment of the present application that period corresponding traffic lights send the color of optical signal for yellow Formula.

Illustrate, " phase place " mentioned in certain some traffic specification typically acquiescence is to be current phase place (such as green light Phase place), i.e., it is that current phase place (such as green light phase place) is referred to as into phase place in certain some traffic specification, in these traffic specifications even Forbidden phase place and transition phase place these concepts are not paid special attention to.It is directed primarily to implement each track in the scheme of the embodiment of the present application The management for comparatively becoming more meticulous, therefore especially these three different phase places of current phase place, forbidden phase place and the transition phase place of differentiation Concept.

In general, continuously current phase place, transition phase place and the forbidden phase place of certain entrance lane can form the entrance The single phase cycling in track, the total duration of two neighboring phase cycling can be fixed (such as shown entrance lane of illustrating in Fig. 2-a The total duration of 01 two neighboring phase cycling is 60 seconds) or the unfixed (phase of the entrance lane 02 as shown in Fig. 2-a citings The total duration of adjacent two phase cyclings).The phase cycling of two entrance lanes of the identical guiding of same Parking Entrance is arranged May be identical (phase cycling of two left turn lanes of the Parking Entrance Y as shown in Fig. 2-b citings is identical) or different.Same entrance The phase cycling of different two entrance lanes being oriented in road is arranged may be identical or different.Under having some scenes, transition phase place Can even is that not, in this case, phase cycling only includes current phase place and forbidden phase place, and does not include transitional face Position.

" crossing conflict track " this conception of species is set forth below, crossing conflict track is relative concept, when certain two entrance car The road track of crossing conflict each other, represents that the driving trace of wagon flow on this two entrance lanes through crossing exists and intersects and (or claims Exist and interweave), i.e. driving trace of the wagon flow on any two entrance lanes in the track of crossing conflict each other through crossing is present Intersect.Such as East and West direction Through Lane and north-south Through Lane crossing conflict each other track, East and West direction Through Lane and north-south There is intersection in driving trace of the wagon flow on Through Lane through crossing, such as shown in Fig. 1-c citings, head west Through Lane and south If the wagon flow on row Through Lane is while through crossing, then, this two bursts of wagon flows will be clashed at crossing.Fig. 1-c are also lifted It is illustrated head west Through Lane and the northern row Through Lane also track of crossing conflict each other, the feelings in other tracks of crossing conflict each other Condition is by that analogy.Conflict track in crossing can referred to as conflict track in the embodiment of the present application.

The concept of " crossing conflict pass through phase place " is set forth below, conflict current phase place in crossing is also relative concept.It is simple next Say, the current phase place of current phase place crossing conflict each other of two entrance lanes in the track of crossing conflict each other.It is similar, road each other The transition phase place transition phase place of crossing conflict each other of two entrance lanes in mouth conflict track.In the embodiment of the present application, crossing punching Prominent current phase place can referred to as conflict current phase place.Crossing conflict transition phase place can referred to as conflict transition phase place.

The concept of " control phase place " and " non-controlling power phase place " is set forth below, the control phase place of entrance lane is used to control The wagon flow made on the entrance lane crosses crossing, can represent that the wagon flow on the entrance lane obtains the right for crossing crossing.Its In, these vehicles of the stop line of certain entrance lane are just crossed in the end of transition phase place (if present) or current phase place, lead to The regular hour is often needed to cross crossing, in order to avoid these vehicles sail the vehicle at crossing into from another crossing track that conflicts In crossing conflict, therefore, proposing in some traffic specifications generally need to be to the time of 2 seconds or so to guarantee in transition phase place (if depositing ) or current phase place end these vehicles of stop line for just crossing can safety cross crossing, in some traffic specifications This section be used to into time for emptying to be referred to as to empty phase place and (wherein, empty phase place similar to alleged in some traffic specifications Crossing full red signal interval).In general, on a timeline, the control phase place of certain entrance lane+non-controlling power phase place=this enters Current phase place+forbidden phase place+transition phase place the (if present) in mouth track.Forbidden phase place may include to empty phase place and non-clear phase Position.Certainly empty phase place be in particular cases likely at some it is dispensable, when empty phase place it is non-existent in the case of, it is forbidden Phase place can be equal to non-controlling power phase place, that is to say, that the non-controlling power phase place of entrance lane is the forbidden of the entrance lane Phase place it is part or all of.In the case of it there is transition phase place and empty phase place, control phase place may include current phase place, mistake Cross phase place and empty phase place.When there is transition phase place and in the case of not existing and emptying phase place, control phase place includes current phase Position and transition phase place.When there is no transition phase place but in the case that presence empties phase place, control phase place include current phase place and Empty phase place.In the case of it there is no transition phase place and empty phase place, control phase place can be equal to current phase place.For example, The control phase place of exemplified certain entrance lane of Fig. 2-c (such as entrance lane x05) includes current phase place, transition phase place and clear Kongxiang position；Or the control phase place of certain entrance lane (such as entrance lane x07) may include current phase place and empty phase place；Or The control phase place of certain entrance lane (such as entrance lane x06) includes current phase place and transition phase place；Or certain entrance car The control phase place in road (such as entrance lane x08) can be equal to current phase place.The phase place mentioned in some traffic specifications also may be used Control phase place can be defaulted as, i.e., be probably that control phase place is referred to as into phase place in these traffic specifications.

The concept of " crossing conflict control weighs phase place " is set forth below, conflict control power phase place in crossing is relative concept, simply For, each other crossing conflict control weighs phase place to the control phase place of two entrance lanes in the track of crossing conflict each other.Crossing rushes Prominent control phase place can abbreviation conflict control power phase place.

What the description above for each conception of species (such as " phase place " concept) was mainly carried out as a example by for track.And pin Some concepts (such as some " phase place " concepts) in track are equally applicable in the scene for crossing.From broadly coming See, crossing and track can all regard walkway as, and walkway is that, for the current road of object that passes through, walkway includes people Row lateral road and track (the such as entrance lane of grade crossing, exit lane) etc..Wherein, the object for passing through on walkway Referred to as pass through object (current object is probably pedestrian or vehicle etc.), and the object data stream passed through on walkway is referred to as current Object data stream (referred to as current stream).The object passed through on crossing may include pedestrian etc., the object passed through on crossing Stream includes pedestrian stream etc..The object passed through for example on track may include vehicle etc., and the object data stream passed through on track includes car Stream etc..

For the scene of crossing, also there may be current phase place, transition phase place and forbidden phase place of crossing etc. general Read, also there may be the concepts such as the control phase place and non-controlling power phase place of crossing.Between crossing and some tracks May conflict each other, because the driving trace of the stream of people on crossing and the wagon flow on certain track there may be intersection.Extensively See in justice, when two walkways, (the two walkways may all be track, or it is track to be likely to one of them, and another Individual is crossing) the travel track of current stream exist and intersect, then the two walkways can mutual referred to as conflict road, mutually Pass through within the identical period for the current stream on two walkways in the road that conflicts, then the current stream on two walkways may be just Clash.If the conflict road of certain walkway (such as track or crossing) is track, this conflict road alternatively referred to as conflicts Track；If the conflict road of certain walkway is crossing, this conflict road alternatively referred to as conflict crossing.Track and track Between may conflict each other, and be likely to conflict each other between track and crossing.Wherein, conflict track and conflict people Row lateral road can be collectively referred to as the road that conflicts.

For ease of simplifying description, in application scheme description, no through traffic, and optical signal can referred to as forbidden optical signal or A1 Class optical signal, it is allowed to which current optical signal can referred to as permit traveling optical signal or current optical signal or A2 class optical signals, the current light letter of warning Number can referred to as or alert traveling optical signal or A3 class optical signals.Specifically, forbidden optical signal is indicated for forbidding corresponding walkway The current optical signal of the current object (such as vehicles or pedestrians) of (such as track or crossing), for example, certain track Traffic lights send forbidden optical signal during forbid the vehicle pass-through in the track, the traffic lights of certain crossing to send The vehicle pass-through of the forbidden crossing during forbidden optical signal.Fair traveling optical signal is indicated for allowing corresponding walkway (such as Track or crossing etc.) the current optical signal of current object (such as vehicles or pedestrians), the traffic letter in such as certain track Signal lamp permits the traffic lights of the vehicle pass-through in the row track, certain crossing to send fair row light letter during sending fair traveling optical signal Number period permits the vehicle pass-through of the row crossing.Alert traveling optical signal is indicated for warning corresponding walkway (such as track or people Row lateral road) the current optical signal of current object (such as vehicle or pedestrian), the traffic lights in such as certain track send police Warn during warning the vehicle pass-through in the track, the traffic lights of certain crossing to send alert traveling optical signal during traveling optical signal The vehicle pass-through of the crossing.Other situations can be by that analogy.

Forbidden optical signal, permit traveling optical signal and alert traveling optical signal concrete appearance form be probably it is flexible and changeable, can root Set according to concrete scene needs.

For example, forbidden optical signal can be red light signal, wherein, red light signal is specifically as follows the redness of flicker Optical signal and/or nonflickering red light signal.Wherein, nonflickering red light signal may be simply referred to as normal red signal light, flicker Red light signal may be simply referred to as flashing red signal.Forbidden optical signal is indicated for that no through traffic object is (such as vehicles or pedestrians Deng) current optical signal, therefore any one can be used to indicate that the current object for forbidding corresponding walkway (such as vehicles or pedestrians Deng) current optical signal is considered as forbidden optical signal, then the form of expression of forbidden optical signal is not limited to the example above, For example also the optical signal of several colors can be combined according to certain rule to indicate to forbid the current right of corresponding walkway As current, then the optical signal of these forms of expression is also regarded as forbidden optical signal.

Again for example, fair traveling optical signal can be green light signal, the green light signal that green light signal concretely flashes and/ Or nonflickering green light signal.Nonflickering green light signal can referred to as evergreen optical signal, the green light signal of flicker can letter Referred to as blue flash optical signal.Fair traveling optical signal is indicated for allowing the current object (such as vehicles or pedestrians) of corresponding walkway to lead to Capable optical signal, therefore, any one can be used to indicate that the current object (such as vehicles or pedestrians) for allowing corresponding walkway Current optical signal is considered as permitting traveling optical signal, then the form of expression for permitting traveling optical signal is not limited to the example above, example As also the optical signal of several colors can be combined according to certain rule to indicate to allow current object to pass through, then these The optical signal of the form of expression is also regarded as permitting traveling optical signal.

Again for example, alert traveling optical signal can be yellow optical signal, the yellow optical signal that yellow optical signal concretely flashes and/ Or nonflickering yellow optical signal.Nonflickering yellow optical signal can abbreviation Chang Huangguang signals, the yellow optical signal of flicker can letter Referred to as yellow flashing signal.Alert traveling optical signal is indicated for warning the current object (such as vehicles or pedestrians) of corresponding walkway to lead to Capable optical signal, therefore, any one can be used to indicate that the current object (such as vehicles or pedestrians) for warning corresponding walkway Current optical signal is considered as warning traveling optical signal, then the form of expression of alert traveling optical signal is not limited to the example above, example As also the optical signal of several colors can be combined for indicating that the current object of warning passes through according to certain rule, then The optical signal of these forms of expression is also regarded as warning traveling optical signal.

Generally speaking, fair traveling optical signal there may be one or more forms of expression, and forbidden optical signal can also be present One or more form of expression, alert traveling optical signal there may be one or more form of expression.But due to permitting traveling optical signal, forbidden light Signal is different with alert traveling optical signal indicative function, then permit the form of expression of traveling optical signal, forbidden optical signal and alert traveling optical signal Also it is different, in other words, the form of expression set of forbidden optical signal, the form of expression set of alert traveling optical signal and forbidden light Do not occur simultaneously between the form of expression set of signal.

Wherein, alert traveling optical signal is indicated for warning the light of the current object (such as vehicles or pedestrians) of corresponding walkway Signal, therefore from certain angle, alert traveling optical signal is considered as a kind of transition signal, and (therefore alert traveling optical signal also can claim For excessive optical signal), indicate current object fair row and it is forbidden between transition.If in some cases without the need for such transition, So it is likely to just without the need for this transition signal of alert traveling optical signal.

For ease of simplifying describing mode, in some schemes description of the application, A1 classes optical signal but can not can be sent The signal lamp for sending A2 classes optical signal and A3 class optical signals can be described as " A1 class signal lamps ".A2 classes optical signal but can not can be sent The signal lamp for enough sending A1 classes optical signal and A3 class optical signals is properly termed as " A2 class signal lamps ".Can send A3 classes optical signal but The signal lamp that A1 classes optical signal and A2 class optical signals can not be sent is properly termed as " A3 class signal lamps ".A1 classes light letter can be sent Number and A2 classes optical signal but the signal lamp of A3 class optical signals can not be sent can be described as " A12 class signal lamps ".A1 classes can be sent Optical signal and A3 classes optical signal but the signal lamp of A2 class optical signals can not be sent can be described as " A13 class signal lamps ".Can send A2 classes optical signal and A3 classes optical signal but the signal lamp of A1 class optical signals can not be sent it is properly termed as " A23 class signal lamps ".It is special Other, the signal lamp that can be sent A1 classes optical signal and can send A2 classes optical signal and A3 class optical signals can be described as " AA classes letter Signal lamp ", by that analogy.

Above simple introduction is done to some related notions that the embodiment of the present application scheme may relate to.

In some technical schemes of the embodiment of the present application, can be on the part or all of entrance lane of grade crossing Crossroad traffic signal lamp array is set.Wherein, the mode of crossroad traffic signal lamp array is set on part or all of entrance lane May be same or like.Carry out citing introduction in greater detail to crossroad traffic signal lamp array below.

The embodiment of the present application provides a kind of crossroad traffic signal lamp array, wherein, the crossroad traffic signal lamp array can With including Nxi horizontal ground traffic signal light group.Wherein, the Nxi horizontal ground traffic signal light group includes being arranged at The horizontal ground traffic signal light group pxi of the safe line position in crossing of the entrance lane xi of grade crossing.Described Nxi horizontal Earthward traffic signal light group also includes the horizontal ground traffic signal light of the parking line position for being arranged at the entrance lane xi Group qxi.

Wherein, the roadway segment delimited between the crossing safety line and stop line of entrance lane forms entrance boot section, entrance Also entrance boot section is regarded as in boot section.For example, between the crossing safety line of entrance lane xi and the stop line of entrance lane xi The roadway segment of delimitation forms the entrance boot section (the entrance boot section of entrance lane xi) of entrance lane xi.

Wherein, any two ground traffic signal light group in the Nxi horizontal ground traffic signal light group includes Signal lamp quantity may be the same or different.Wherein, the Nxi is the integer more than 1.The Nxi horizontal ground traffic signal light Each horizontal ground traffic signal light group in group includes at least one signal lamp (such as 1 or at least 2 signal lamps).

For example, Nxi can for example be equal to 2,3,5,7,8,10,11,29,36,50,100 or other values.

Wherein, in horizontal ground traffic signal light group i at least one (such as 1 or at least two) is driven with wireless type Dynamic signal input port and/or wired driving signal input mouth.The horizontal ground traffic signal light group i is the Nxi One of them horizontal ground traffic signal light group or any one horizontal traffic above-ground in individual horizontal ground traffic signal light group Signal lamp group.

Wherein, any two adjacent transverse ground traffic signal light in the Nxi horizontal ground traffic signal light group Spacing between group is equal or part is equal or is not mutually equal.For example, any two in Nxi horizontal ground traffic signal light group Spacing between individual adjacent transverse ground traffic signal light group can be 1 meter, 1.5 meters, 2 meters, 2.5 meters, 3 meters or other values. Again for example, it is more remote apart from the horizontal ground traffic signal light group pxi in the Nxi horizontal ground traffic signal light group Spacing between two adjacent transverse ground traffic signal light groups it is less (i.e. in the travel direction of entrance lane xi, the Nxi The spacing between two adjacent transverse ground traffic signal light groups in individual horizontal ground traffic signal light group gradually increases), or In Nxi described in person horizontal ground traffic signal light group, apart from two more remote phases of the horizontal ground traffic signal light group pxi Adjacent spacing laterally between the traffic signal light group of ground is less, and (i.e. in the travel direction of entrance lane xi, the Nxi laterally The spacing between two adjacent transverse ground traffic signal light groups in ground traffic signal light group is gradually reduced).Certainly, it is described The Nxi spacing laterally between the two adjacent transverse ground traffic signal light groups of traffic signal light group of ground is also likely to be arbitrarily to become Change or other Changing Patterns, and not necessarily present the change for being gradually reduced along certain direction or gradually increasing of the example above Rule.

For example, it is not only arranged at two neighboring in the Nxi of entrance boot section horizontal ground traffic signal light group Laterally spacing can be equal between the traffic signal light group of ground, and adjacent in the Nxi horizontal ground traffic signal light group Two horizontal ground traffic signal light groups send the initial time of fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) Interval also can be equal, and this pattern can claim " equidistant isochronous mode ".Again under such as some scenes, entrance boot section is arranged at The two neighboring horizontal ground traffic signal light group horizontal in the traffic signal light group of ground of Nxi between spacing can be equal, But the two neighboring horizontal ground traffic signal light group in the Nxi horizontal ground traffic signal light group sends fair row light letter The interval of the initial time of number (or forbidden optical signal or alert traveling optical signal), this pattern can claim " mould when equidistantly not waiting Formula ".Again for example, under having some scenes, adjacent two be arranged in the Nxi of entrance boot section horizontal ground traffic signal light group Spacing between individual horizontal ground traffic signal light group is unequal, but the phase in the Nxi horizontal ground traffic signal light group Adjacent two horizontal ground traffic signal light groups send the initial time of fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) Interval it is equal, this pattern can claim " unequal-interval pattern when waiting ", and isochronous mode can be not by that analogy for unequal-interval.

Specifically for example, it is assumed that Nxi is equal to 11, the entrance guiding section length of entrance lane xi is 10 meters, then Nxi horizontal Ground traffic signal light group can uniformly branch between the crossing safety line and stop line of entrance lane xi, such as in entrance car Every 1 meter of setting, one horizontal ground traffic signal light group in the entrance boot section of road xi, Nxi horizontal ground traffic signal light The entrance boot section of entrance lane xi is divided into 10 entrance lane sections, the horizontal ground traffic signal light of arbitrary neighborhood two by group Spacing between group is 1 meter, and the horizontal ground traffic signal light group of arbitrary neighborhood two sends fair traveling optical signal (or forbidden light letter Number or alert traveling optical signal) initial time interval can equal (such as 0.2 second, 1 second, 1.5 seconds or 2 seconds) or.Again for example Assume that Nxi is equal to 6, the entrance guiding section length of entrance lane xi is 10 meters, then Nxi laterally ground traffic signal light group can Uniform branch between the crossing safety line and stop line of entrance lane xi, such as in the entrance boot section of entrance lane xi One horizontal ground traffic signal light group is set every 2 meters, and Nxi laterally ground traffic signal light group can be by entrance lane xi's Entrance boot section is divided into 5 entrance lane sections, and the spacing between the horizontal ground traffic signal light group of arbitrary neighborhood two is 2 meters The horizontal ground traffic signal light group of arbitrary neighborhood two sends rising for fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) The interval at moment beginning can be equal or different.Wherein, the Nxi laterally in the traffic signal light group of ground it is two neighboring laterally Other equal set-up modes of spacing can be by that analogy between the traffic signal light group of face.

Wherein, when the horizontal ground traffic signal light group i includes at least two signal lamps, then hand on the horizontal ground The shared identical drive signal of at least two signal lamps among ventilating signal lamp group i, or the horizontal ground traffic signal light group i Among any two signal lamp use different drive signals.

It is understood that as a rule, the working condition for sharing several signal lamps of identical drive signals is synchronous change Change, for example sharing several signal lamps of identical drive signal will simultaneously be lighted or be closed simultaneously, because these letters Signal lamp is to carry out drive control in the lump by identical drive signals.Can using the working condition of different two signal lamps of drive signal Can not be synchronous change, certainly it could also be possible that synchronous change.In general, using from same drive signal output end The drive that mouth (drive signal output port can refer to the drive signal output port of array driver or traffic signaling equipment etc.) is exported The working condition of the signal lamp of dynamic signal is synchronous change, if actual conditions is the driving that drive signal output port is exported Signal sequential etc. during from drive signal output port arriving signal lamp is not changed.In general, using from not The working condition of the signal lamp of the drive signal exported with drive signal output port may not be synchronous change, certainly It is likely to be synchronous change.

Wherein, entrance lane xi can be grade crossing wherein one entrance lane, or entrance lane xi with can For any one entrance lane of intersection.That is, the part or all of entrance lane of grade crossing can be pressed Horizontal ground traffic signal light group etc. is disposed according to the deployment way equivalent or similar to entrance lane xi.

It is appreciated that because the signal lamp in horizontal ground traffic signal light group is arranged at ground, therefore these signals Lamp is also referred to as ground traffic signal light (can also referred to as " ground signal lamp ").If without special explanation, the application is implemented Signal lamp in the horizontal ground traffic signal light group referred among example is ground traffic signal light.It is appreciated that due to ground Face traffic lights are arranged at ground, therefore on set-up mode and product form, ground traffic signal light is to be different from height Empty traffic lights, high altitude traffic signal lamp for example may include column traffic lights or cantilevered traffic lights etc..

It is appreciated that laterally " horizontal " in the traffic signal light group of ground is intended to mean that horizontal ground traffic signal light group The travel direction in length direction and corresponding track is perpendicular or generally perpendicular, the length of at least horizontal ground traffic signal light group It is uneven, the length direction and corresponding car of horizontal ground traffic signal light group between the travel direction in direction and corresponding track Angular range between the travel direction in road can be more than or equal to 45 ° and less than or equal to 90 °, and above-mentioned angle for example can be equal to 90 °, 89 °, 85 °, 80 °, 78 °, 75 °, 60 °, 53 ° or 40 °.Certainly, the length direction of horizontal ground traffic signal light group and Angular range between the travel direction in corresponding track is not limited to the example above scope.

Optionally, in some possible embodiments of the application, when the Nxi is the integer more than 2, the Nxi is individual Laterally ground traffic signal light group also includes the crossing safety line and the stop line being arranged on the entrance lane xi Between the horizontal ground traffic signal light group of Nxi-2.It is understood that Nxi-2 (such as Nxi=6, then Nxi-2 =6-2=4, by that analogy) individual horizontal ground traffic signal light group potentially include be arranged at it is described on the entrance lane xi Some or all of horizontal ground traffic signal light group between crossing safety line and stop line.

As can be seen that the crossroad traffic signal lamp array that the present embodiment is provided includes Nxi laterally ground traffic signal light Group；The Nxi horizontal ground traffic signal light group includes：It is arranged on the crossing safety of the entrance lane xi of grade crossing The horizontal ground traffic signal light group pxi of line position, the horizontal traffic above-ground of the parking line position for being arranged on entrance lane xi are believed Signal lamp group qxi.Because the roadway segment delimited between the crossing safety line and stop line of entrance lane xi can form entrance boot section, This just for vehicle by the advance acceleration at crossing provide certain space basis, and for control vehicle sail crossing into speed (i.e. Vehicle rolls the speed of entrance boot section away from) and transport condition of the vehicle in entrance boot section provide certain basis, and then cause Improving the vehicle pass-through efficiency of grade crossing becomes had certain space basis.Such as Nxi horizontal ground traffic signals Entrance boot section can be divided into several roadway segments by lamp group, using the Nxi light that laterally ground traffic signal light group is sent Signal so that the speed that transport condition and vehicle of the vehicle in entrance boot section rolls entrance boot section away from is more accurately controlled System becomes had possible, therefore the safely controllable property of the vehicle pass-through for being so conducive to improving grade crossing.Also, ground The traffic signal light group of the formula driver that is more convenient for identifies corresponding traffic control signal, and then is conducive to further improving plane The vehicle pass-through safely controllable property of intersection.

Some explanations are carried out below in conjunction with the accompanying drawings.Fig. 3 is referred to, Fig. 3 shows that certain Parking Entrance of having illustrated out is being arranged laterally Road conditions before the traffic signal light group of face.The Parking Entrance (Parking Entrance X) of the left-hand component citing of Fig. 3 and right-hand component citing Parking Entrance (Parking Entrance Y) respectively include 3 entrance lanes.Parking Entrance includes the situation of the entrance lane of other quantity with such Push away.Parking Entrance Y fronts shown in the citing of Fig. 3 right-hand components also have crossing, the entrance shown in the left-hand component citing of Fig. 3 X fronts in road do not have crossing.

Referring to Fig. 4-a~Fig. 4-c, Fig. 4-a~Fig. 4-c are exemplified in the front entrance lane with crossing The upper several possible road conditions arranged after horizontal ground traffic signal light group.Entrance in scene shown in Fig. 4-a citings The horizontal ground traffic signal light group of the relevant position arranged on each entrance lane in road is generally within same straight line.Fig. 4-b In scene shown in citing, the horizontal ground traffic signal light group of the relevant position arranged on the partial inlet track of same Parking Entrance Generally within same straight line, the horizontal ground traffic signal light group of the relevant position arranged on another part entrance lane is basic Be located along the same line, in addition same Parking Entrance have some entrance lanes stop line and other entrance lanes stop line May not be on the same line.

Wherein, every entrance lane is mainly equal to as a example by 4 by Nxi in the left-hand component example and Fig. 4-b of Fig. 4-a (at least 4 horizontal ground traffic signal light groups are set on i.e. every entrance lane).Wherein, the right-hand component example of Fig. 4-a and For every entrance lane in the right-hand component example of Fig. 4-c, mainly it is equal to as a example by 2 by Nxi.Nxi is equal to the situation of other values Can be by that analogy.

It is appreciated that the quantity of the horizontal ground traffic signal light group arranged on each entrance lane of same Parking Entrance can phase Deng or.The quantity of the horizontal ground traffic signal light group arranged on the entrance lane of different Parking Entrances can be equal or different.

In the application some possible embodiments, the signal lamp ia energy among the horizontal ground traffic signal light group i It is enough that forbidden optical signal is sent under the driving of the first drive signal, and the signal lamp ia can also be in the drive of the second drive signal Fair traveling optical signal is sent under dynamic, the signal lamp ia for example can be A12 class signal lamps.Or the horizontal ground traffic signal light Signal lamp ia among group i can send forbidden optical signal under the driving of the first drive signal, and the signal lamp ia can also It is enough that fair traveling optical signal is sent under the driving of the second drive signal, and the signal lamp ia can also be in the drive of the 3rd drive signal Dynamic to issue responding traveling optical signal, the signal lamp ia for example can be AA class signal lamps.Wherein, the signal lamp ia can be the horizontal stroke The earthward one of signal lamp or any one signal lamp among traffic signal light group i.That is, the application some In possible embodiment, individual signals lamp can send different optical signals under the driving of different driving signal.Specifically for example, ground Part or all of signal lamp among the traffic signal light group i of face can send red light letter under the driving of the first drive signal Number, and the part or all of signal lamp among ground traffic signal light group i can send green under the driving of the second drive signal Part or all of signal lamp among optical signal, and ground traffic signal light group i can be issued in the driving of the 3rd drive signal Go out yellow optical signal.

Optionally, in the application some possible embodiments, the part among the horizontal ground traffic signal light group i Or whole signal lamps are railway spike or light bar (such as LED) or Graphene signal lamp.Certainly, horizontal ground traffic signal light group In the product form of signal lamp be also not necessarily limited to the example above.For example, the signal among horizontal ground traffic signal light group i Lamp ia may include：V lamp bead, the circuit board for driving the V lamp bead work and for accommodating the V lamp bead and described The housing of circuit board.Wherein, the circuit board has wired driving signal input mouth and/or the input of wireless type drive signal Port, wherein, the V is the integer more than or equal to 1.Wherein, V for example can be equal to 1,2,3,5,7,8,10,21,29,36, 50th, 100 or other values.Such as described V lamp bead may include：V1 lamp bead of forbidden optical signal can be sent, can send fair V2 lamp bead of traveling optical signal and/or v3 lamp bead of alert traveling optical signal can be sent.The v1 and v2 and the v3 are equal It is the integer more than 1 or equal to 1.

Optionally, in some possible embodiments of the application, the Nxi laterally ground traffic signal light group it In the horizontal ground traffic signal light group of two of which can begin to send out forbidden optical signal or fair row light in different initial times Signal or alert traveling optical signal.Or the horizontal ground traffic signals of any two in the Nxi horizontal ground traffic signal light group Lamp group can begin to send out forbidden optical signal or fair traveling optical signal or alert traveling optical signal in different initial times.Or the Nxi Laterally the horizontal ground traffic signal light group of any two in the traffic signal light group of ground can start to send out in identical initial time Go out forbidden optical signal or fair traveling optical signal or alert traveling optical signal.Or it is any in the Nxi horizontal ground traffic signal light group Two horizontal ground traffic signal light groups can begin to send out forbidden optical signal or fair traveling optical signal or police in identical initial time Traveling optical signal.

Optionally, in the application some possible embodiments, the Nxi laterally in the traffic signal light group of ground away from From the horizontal ground traffic signal light group qxi more close to horizontal ground traffic signal light group send forbidden optical signal (or permit Traveling optical signal or alert traveling optical signal) initial time it is more early.The horizontal ground traffic signal light group pxi sends forbidden optical signal Initial time, be later than other any one the horizontal ground traffic signals of the Nxi laterally in the traffic signal light group of ground Lamp group sends the initial time of forbidden optical signal (or fair traveling optical signal or alert traveling optical signal).As an example it is assumed that the Nxi Horizontal ground traffic signal light group is including horizontal ground traffic signal light group j1, horizontal ground traffic signal light group j2 and laterally Face traffic signal light group j3.The horizontal ground traffic signal light group j1, the horizontal ground traffic signal light group j2 and described Laterally ground traffic signal light group j3 is adjacent 3 in the Nxi position laterally among the traffic signal light group of ground (such as wherein 3 or any 3) horizontal ground traffic signal light group.Wherein, the horizontal ground traffic signal light group j2 and institute The spacing stated between the stop line of entrance lane xi is more than, the horizontal ground traffic signal light group j1 and entrance lane xi Stop line between spacing.Wherein, the stop line of the horizontal ground traffic signal light group j2 and entrance lane xi it Between spacing, less than the spacing between the horizontal ground traffic signal light group j3 and the stop line of the entrance lane xi.

It is appreciated that the horizontal ground traffic signal light group j1 may be exactly horizontal ground traffic signal light group qxi, The horizontal traffic above-ground letter that may be disposed between the crossing safety line and the stop line on the entrance lane xi Signal lamp group.Laterally ground traffic signal light group j3 may be exactly horizontal ground traffic signal light group pxi, it is also possible to be disposed on institute State the horizontal ground traffic signal light group between the crossing safety line and the stop line on entrance lane xi.

It is understood that working as above-mentioned V_{j1_j2}Equal to V_{j2_j3}, then horizontal ground traffic signal light group j1, described can be represented Laterally the ground traffic signal light group j2 and horizontal ground traffic signal light group j3 (or is prohibited by sending fair traveling optical signal successively Traveling optical signal or alert traveling optical signal) the guiding speed that presented is at the uniform velocity.And work as above-mentioned V_{j1_j2}Less than above-mentioned V_{j2_j3}, then Horizontal ground traffic signal light group j1, the horizontal ground traffic signal light group j2 and the horizontal ground traffic signals can be represented Lamp group j3 is even by sending the guiding speed that fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) is presented successively Accelerate or non-even acceleration.

It is appreciated that the powered Nxi horizontal ground traffic signal light group is from the horizontal ground traffic signals Lamp group qxi starts to send fair traveling optical signal successively, can present and at the uniform velocity guide speed, can also present even acceleration or non-even acceleration Speed change guiding speed, be so advantageous for the travel speed to vehicle in entrance boot section and guide safely.

For example, when horizontal ground traffic signal light group qxi sends fair traveling optical signal, representing current allows entrance lane Vehicle on xi crosses horizontal ground traffic signal light group qxi (allows the vehicle on entrance lane xi to cross entrance lane xi Stop line), vehicle (such as the head car after being stopped at horizontal ground traffic signal light group qxi) sail into entrance boot section it Afterwards, other the horizontal ground in Nxi laterally ground traffic signal light group in addition to horizontal ground traffic signal light group pxi are handed over Under the guiding of the fair traveling optical signal that ventilating signal lamp group sends successively, vehicle progressively cross these horizontal strokes for sending fair traveling optical signal Earthward traffic signal light group, sends under the guiding of fair traveling optical signal afterwards, vehicle in horizontal ground traffic signal light group pxi Horizontal ground traffic signal light group pxi (that is, crossing the crossing safety line of entrance lane xi) is crossed, vehicle is crossing horizontal ground Just crossing is entered after traffic signal light group pxi into crossing or after crossing is passed through, finally cross crossing entrance Respective downstream track.Generally speaking, in Nxi horizontal ground traffic signal light group from the horizontal ground traffic signal light group Guiding speed that qxi starts to send fair traveling optical signal successively and presents (guiding speed be probably at the uniform velocity or it is non-at the uniform velocity) guiding Under, vehicle will cross entrance boot section with the travel speed less than or equal to this guiding speed.It is appreciated that on horizontal ground Traffic signal light group pxi is sent before fair traveling optical signal, if vehicle in entrance more than respective guide speed travel speed drawing Lead area's traveling, then, vehicle is just likely to " making a dash across the red light " phenomenon occur, that is, be likely to vehicle occur on certain horizontal ground Traffic signal light group sends before fair traveling optical signal that (wherein, this horizontal ground traffic signal light group is sending fair traveling optical signal OFF state is may be at before or sends the state of forbidden optical signal) just cross this horizontal ground traffic signal light group Phenomenon, this phenomenon is certainly very unsafe.It can be seen that, be conducive to car using Nxi horizontal ground traffic signal light group Travel speed in entrance boot section is guided safely, and then is advantageously allowed vehicle and sailed crossing into safer speed, So not only improve lifting vehicle and cross crossing efficiency, be also beneficial to ensure the security that vehicle crosses crossing.That is, this The scheme of application embodiment, is conducive to accomplishing to take into account substantially in terms of vehicle crosses the efficiency and security at crossing.

The embodiment of the present application also provides the drive control method of crossroad traffic signal lamp array, the crossroad traffic signal lamp Array for example can be such as any one crossroad traffic signal lamp array of above-mentioned embodiment offer.Concrete such as crossroad traffic signal lamp Array includes Nxi laterally ground traffic signal light group；The Nxi horizontal ground traffic signal light group includes being arranged at plane The horizontal ground traffic signal light group pxi of the safe line position in crossing of the entrance lane xi of intersection, the Nxi laterally Face traffic signal light group also includes the horizontal ground traffic signal light group of the parking line position for being arranged at the entrance lane xi qxi.Each horizontal ground traffic signal light group in the Nxi horizontal ground traffic signal light group includes at least one (for example 1 or at least two) signal lamp.Laterally the part or all of signal lamp among the traffic signal light group i of ground has wireless type to drive Dynamic signal input port and/or wired driving signal input mouth.The horizontal ground traffic signal light group i is the Nxi One of them horizontal ground traffic signal light group or any one horizontal ground among individual horizontal ground traffic signal light group is handed over Ventilating signal lamp group.

Wherein, if the horizontal ground traffic signal light group i includes at least two signal lamps, then hand on the horizontal ground At least two signal lamps in ventilating signal lamp group i can share identical drive signal, or, the horizontal ground traffic signal light Any two signal lamp in group i uses different drive signals.

Wherein, a kind of drive control method of crossroad traffic signal lamp array may include：When the control of the entrance lane xi The upper crossing conflict control power phase place of system power phase place terminates also to remain overlap duration T_{cd_xi}When, drive described Nxi laterally Face traffic signal light group starts to send fair traveling optical signal successively from the horizontal ground traffic signal light group qxi.Described Nxi horizontal Earthward horizontal ground traffic signals horizontal ground traffic signal light group qxi nearer described in the distance among traffic signal light group The initial time that lamp group sends fair traveling optical signal by driving is more early, and the horizontal ground traffic signal light group pxi is sent by driving The initial time of fair traveling optical signal, be later than other of the Nxi laterally in the traffic signal light group of ground any one laterally Face traffic signal light group is sent the initial time of fair traveling optical signal by driving.For example can be by detection (directly or indirectly detection) When the progress of the upper crossing conflict control power phase place of the control phase place of the entrance lane xi is entrance car to learn The upper crossing conflict control power phase place of the control phase place of road xi terminates also to remain overlap duration T_{cd_xi}When.

It is to be appreciated that the corresponding duration that overlaps of the different entrance lane of the travel direction of approximately the same plane intersection may Equal or part is equal or is not mutually equal.The entrance lanes that travel direction is identical but guiding is different of approximately the same plane intersection The equal or part of corresponding overlap duration possibility is equal or is not mutually equal.The travel direction and guiding of approximately the same plane intersection The entrance lane of all same is corresponding overlap duration may equal or part it is equal or be not mutually equal.It is appreciated that overlapping duration T_{cd_xi}For the corresponding overlap durations of entrance lane xi, entrance lane xi for grade crossing one of entrance lane or appoint One entrance lane of meaning.

It is the upper crossing punching that the horizontal ground traffic signal light group pxi sends the initial time of fair traveling optical signal Prominent control phase place finish time.That is, described horizontal ground traffic signal light group pxi and horizontal ground traffic signal light group qxi Send the interval T of the initial time of fair traveling optical signal_{Δ_pxi_qxi}Equal to overlap duration T_{cd_xi}.Overlap duration T_{cd_xi}It can be storage Preset value (can update currently stored T according to the duration more new command that overlaps from upper equipment or Man Machine Interface_{cd_xi}) Or overlap duration T_{cd_xi}Can be in real time calculated based on preset algorithm.For example overlap duration T_{cd_xi}Can be equal to 2 seconds, 3 seconds, 4 seconds, 5 Second, 6 seconds, 7 seconds, 8.1 seconds, 10 seconds or other durations.

As an example it is assumed that the entrance lane xi is eastbound Through Lane, then the control of the entrance lane xi The upper crossing conflict control power phase place of phase place for example may be the southern row Through Lane or northern row of the grade crossing The control phase place of Through Lane or head west left turn lane or northern row left turn lane because, grade crossing it is eastbound straight Runway, with the southern row Through Lane of the grade crossing or northern row Through Lane or head west left turn lane or a northern row left side Conflict each other track between changing trains or buses.Again it is assumed that the entrance lane xi is the Through Lane that heads west, then the entrance lane xi Control phase place upper crossing conflict control power phase place for example may be the grade crossing southern row straight traffic The control phase place in road or northern row Through Lane or eastbound left turn lane or southern row left turn lane, because the west of grade crossing Row Through Lane, with the southern row Through Lane of the grade crossing or northern row Through Lane or eastbound left turn lane or southern row Conflict each other track between left turn lane, and other conflict situations are by that analogy.

For example in scene shown in Fig. 5-a citings, north-south left turn lane, East and West direction left turn lane, north-south straight traffic Road, the control phase place of East and West direction Through Lane are circulated.Wherein, upper of the control phase place of north-south left turn lane Crossing conflict control power phase place for East and West direction left turn lane control phase place, the control phase place of East and West direction left turn lane it is upper One crossing conflict control weighs control phase place of the phase place for north-south Through Lane, the control phase place of north-south Through Lane Upper crossing conflict control power phase place for East and West direction Through Lane control phase place.In scene shown in Fig. 5-a citings, The entrance lane xi is assumed for certain entrance lane in the left turn lane of north-south, then the control of the entrance lane xi The upper crossing conflict control power phase place of phase place is the control phase place of East and West direction left turn lane, and the entrance lane is assumed again Xi is certain entrance lane in East and West direction left turn lane, then a upper crossing of the control phase place of the entrance lane xi Conflict control power phase place is the control phase place of north-south Through Lane, by that analogy.

In scene shown in Fig. 5-a citings, north-south left turn lane is overlap with the control phase place of East and West direction left turn lane Shi Changwei T_{cd_3}.A length of T when East and West direction left turn lane is overlap with the control phase place of north-south Through Lane_{cd_2}.North-south is straight A length of T when runway is overlap with the control phase place of East and West direction Through Lane_{cd_1}.The control phase place of East and West direction Through Lane A length of T when overlap with the control phase place of north-south left turn lane_{cd_4}.Wherein, T_{cd_1}、T_{cd_2}、T_{cd_2}And T_{cd_4}Can whole phases Deng or part it is equal or be not mutually equal.

As can be seen that because the roadway segment delimited between the crossing safety line and stop line of entrance lane xi can form entrance Boot section, this just provides certain space basis for vehicle by the advance acceleration at crossing, and sails crossing into control vehicle The transport condition of speed (i.e. vehicle rolls the speed of entrance boot section away from) and vehicle in entrance boot section provides certain basis, enters And cause the vehicle pass-through efficiency for improving grade crossing to become had certain space basis.Such as Nxi laterally ground friendship Entrance boot section can be divided into several roadway segments by ventilating signal lamp group, be sent out using Nxi horizontal ground traffic signal light group The optical signal for going out so that the speed that transport condition and vehicle of the vehicle in entrance boot section rolls entrance boot section away from is carried out more Precise control becomes had possible, therefore, be so conducive to the safely controllable property of the vehicle pass-through of raising grade crossing.And And, the traffic signal light group of the ground type driver that is more convenient for identifies corresponding traffic control signal, and then is conducive to further Improve the vehicle pass-through safely controllable property of grade crossing.Specifically, by flexibly Nxi horizontal ground traffic signals of control Each horizontal ground traffic signal light group in lamp group send fair traveling optical signal or alert traveling optical signal or forbidden optical signal it is initial when Carve, be advantageously implemented to vehicle by time during crossing and the relatively precise control of speed, and then be conducive to further improving flat The vehicle pass-through safely controllable property of face intersection.For example when a upper crossing of the control phase place of the entrance lane xi rushes When prominent control phase place terminates also to remain corresponding overlap duration, described Nxi horizontal ground traffic signal light group is driven from the horizontal stroke Earthward traffic signal light group qxi starts to send fair traveling optical signal successively, wherein, Nxi laterally ground traffic signal light group it In the nearer horizontal ground traffic signal light groups of the horizontal ground traffic signal light group qxi of distance, send rising for fair traveling optical signal Beginning, the moment is more early, and this just can consider that each horizontal ground traffic signal light group in Nxi horizontal ground traffic signal light group is Fair traveling optical signal is begun to send out successively according to certain order, and this is just the time to vehicle by entrance boot section and speed Degree carries out rationally suitable guiding and lays a good foundation, for example, advantageously allow vehicle in Nxi horizontal ground traffic signal light group It is safely controllable efficiently to roll entrance boot section, Jin Eryou away under the guiding of the guiding speed that the optical signal for being sent is presented Crossing is crossed in safely controllable efficient mode beneficial to vehicle is made.

It is understood that in actual applications, the powered Nxi laterally ground traffic signal light group from described Laterally ground traffic signal light group qxi starts to send fair traveling optical signal successively, and can present at the uniform velocity guide speed or speed change guiding Speed, speed change guiding speed can be that (it is zero that wherein, even acceleration guiding speed can be divided into initial velocity to even acceleration guiding speed The even even acceleration for accelerating guiding speed and initial velocity to be not zero guiding speed) or non-even acceleration guiding speed.

Concrete example, for powered Nxi horizontal ground traffic signal light group is by from horizontal ground traffic signal light group Qxi starts to send fair traveling optical signal successively and presents the situation that at the uniform velocity guides speed, then, Nxi horizontal ground traffic signal light group In horizontal ground traffic signal light group i send the initial time of fair traveling optical signal, send out relative to horizontal ground traffic signal light group qxi The interval duration for going out the initial time of fair traveling optical signal is expressed as T_{Δg_i_qxi}, wherein,

Again for example, for powered Nxi horizontal ground traffic signal light group is by from horizontal ground traffic signal light Group qxi starts to send fair traveling optical signal successively and present the situation that the even acceleration that initial velocity is 0 guides speed, and Nxi laterally Horizontal ground traffic signal light group i in ground traffic signal light group sends the initial time of fair traveling optical signal, relative to horizontal Ground traffic signal light group qxi sends the interval duration of the initial time of fair traveling optical signal and is expressed as T_{Δg_i_qxi}, wherein,As the even initial velocity v for accelerating to guide speed₀Universal expression during more than 0 Formula can be：

Wherein, the T_{cd_xi}Represent the corresponding overlap durations of entrance lane xi, T_{cd_xi}It is also equal to horizontal ground traffic signals The interval duration of the initial time of fair traveling optical signal is sent between lamp group pxi and horizontal ground traffic signal light group qxi.It is described L_{YD_xi}Represent spacing (the i.e. entrance guiding head of district of entrance lane xi between the stop line and crossing safety line of entrance lane xi Degree), the L_{YD_xi}The spacing being also equal between horizontal ground traffic signal light group pxi and horizontal ground traffic signal light group qxi. The L_{i_qxi}The spacing between horizontal ground traffic signal light group i and horizontal ground traffic signal light group qxi is represented, it is described L_{i_qxi}The spacing being also equal between horizontal ground traffic signal light group i and the stop line of entrance lane xi.Wherein, horizontal ground is handed over Ventilating signal lamp group i is any one the horizontal ground traffic signal light group in Nxi horizontal ground traffic signal light group.

Wherein, L_{YD_xi}And/or T_{cd_xi}Value can immobilize, also can be varied from environmental change.Generally come Say, for the consideration of secure context, the first car after the stop line of entrance lane xi sails the speed most benefit at crossing into In safe range, such as km of speed per hour 15 or 20 kms are exactly the safe scope of comparison.If the travel speed of first car is in In safe range, then first car generally just can in time brake when there are crossing emergency situations, and this is advantageously reduced road occurs The probability of mouth accident.For the consideration of these secure contexts, using permitting that the Nxi horizontal ground traffic signal light group sends The guiding speed that traveling optical signal is presented, the travel speed that first car sails crossing into is guided to safe range, then Crossing security is just more secure.

Such as common vehicle is exactly to obtain from the duration that accelerates to needed for safe speed is started toReference basis, Common vehicle is exactly to obtain from the distance that accelerates to needed for safe speed is started toReference basis.Represent into The corresponding plan initial values for overlapping duration of mouth track xi,The plan for representing the entrance guiding section length of entrance lane xi is used Initial value.

Wherein, L_{YD_xi}Value is equal toT_{cd_xi}Value is equal toOr for L_{YD_xi}And/or T_{cd_xi}Value situation about can be varied from environmental change,

Wherein, the μ 1 is the first safety coefficient, and the μ 2 is the second safety coefficient.That is, can be according to working as front ring The change of border factor is based on selecting corresponding safety coefficient(or) and currently selected safety Coefficient is obtaining currently used T_{cd_xi}(or L_{YD_xi}) value.

The value of μ 1 (or μ 2) can be equal to the value of 1, μ 1 (or μ 2) and be also greater than 1 or less than 1.The value example of μ 1 (or μ 2) Such as may be referred to weather, light intensity, the gradient and/or crossing complexity environmental factor to determine.(or 1/ μ of μ 1 for example when fine day 2) value can be equal to 1 or close to 1 (such as 1.1,1.05 or other values), when the rainy day μ 1 (or μ 2) value (such as 1.2, 1.3rd, 1.5,2 or other values) more than when fine day μ 1 (or μ 2) value.And the value of μ 1 (or μ 2) for example when light intensity is preferable 1 can be equal to or close to 1 (such as 1.1 or 1.05 or other values), when light intensity is poor μ 1 (or μ 2) value (such as 1.2, 1.3rd, 1.5,2 or other values) more than when light intensity is preferable μ 1 value.Again for example, the value of μ 1 (or μ 2) when the gradient is less 1 can be equal to or close to 1 (such as 1.1,1.06 or other values), the value of the μ 1 (or μ 2) when the gradient is less is (for example 1.2nd, 1.3,1.5,1.8,2 or other values) value more than μ 1 when the gradient is larger.The μ 1 for example when crossing complexity is less The value of (or μ 2) be equal to 1 or close to 1 (as 1.1,1.04,1.08 or other values), and the μ 1 when crossing complexity is larger (or μ 2) value (as 1.2,1.3,1.5,1.7,1.9,1.8,2 or other values) more than μ 1 (or μ 2) when the gradient is less Value.

It is appreciated that it is to improve security to arrange one of purpose of μ 1 (or μ 2), therefore the value of μ 1 (or μ 2) is also possible to With reference to other, one or more affect safe factor to determine.Which affects the factor of safety with specific reference to, how with reference to shadow Ring safe each factor to determine the value of μ 1 (or μ 2), can be selected according to concrete scene needs, be not particularly limited to herein.

Again for example, corresponding relation, i.e. different periods can draw with entrance between different periods and parking line position Lead section length L_{YD_xi}Between can have corresponding relation.For example, the corresponding parking line position of peak hours/period can be pre-set (for example This period L_{YD_xi}For 10 meters or other values), half peak hours/period corresponding parking line position (such period L_{YD_xi}For 8 meters), it is idle Period corresponding parking line position (such as this period L_{YD_xi}For 6 meters) etc..For example can be by 7：30~9:30、17:30~20:00 Delimit as peak hours/period, 0:00~6:00 to delimit be idle period, and it is half peak hours/period that other delimited periods, and certainly correspondence is not May also there are other to obtain Time segments division mode with application scenarios, no longer illustrate one by one herein.

Again for example, corresponding relation, i.e. different periods can guide with entrance between vehicle flowrate and parking line position Section length L_{YD_xi}Between can have corresponding relation.The L for example when the vehicle flowrate at crossing is more than 100 per minute_{YD_xi}For 10 meters or Other values, entrance guiding section length L when the vehicle flowrate at crossing is 60~100 per minute_{YD_xi}For 8 meters or other values.Work as road Entrance guiding section length L when the vehicle flowrate of mouth is less than 30 per minute_{YD_xi}For 6 meters or other values, other situations are by that analogy.

Additionally, the size of grade crossing, it is right also can to have between corresponding overlapping time and entrance guiding section length Should be related to, such as relatively large grade crossing, overlapping time and entrance guiding section length can be relatively large.And relatively Little grade crossing, overlapping time and entrance guiding section length can be relatively small.

When control phase place includes emptying phase place, current some traffic specifications regulations empty phase place, and (crossing is complete Red signal interval) duration be fixed as 2 seconds, it is contemplated that the length that empties in the different tracks of Different Plane intersection may phase not to the utmost Together, the length that empties in the different tracks of approximately the same plane intersection is likely to be not quite similar, and empties a length of particular value during phase place Might not be most scientific.Therefore, it can consider to obtain corresponding emptying phase place duration T according to the length that empties in track_qk.Example Such asOr work asDuring more than or equal to 2 secondsAnd work as T during less than 2 seconds_{qk_xi}Value is 2 seconds.T_{qk_xi}Represent that entrance lane xi's empties phase place duration.L_{qk_xi}Represent entrance lane xi pair That what is answered empties length (L_{qk_xi}The corresponding crossing length of entrance guiding section length+entrance lane xi equal to entrance lane xi). V'_{lk_xi}For example equal to minimum speed limit V of the affiliated grade crossings of entrance lane xi_{lk_min}Or desired speed V_{lk_q}.Or V'_{lk_xi} V can be equal to_{lk_min}* μ 3 or V_{lk_q}* μ 3, the value of the 3rd safety coefficient μ 3 can be equal to 1 or more than 1 or less than 1.Specifically, μ 3 Value for example may be referred to the environmental factors such as weather, light intensity, the gradient and/or crossing complexity to determine, the concrete value side of μ 3 Formula refers to the concrete value mode of μ 1.

Based on T obtained from the mode of the example above_{qk_xi}Can not be fixed duration 2 seconds, T_{qk_xi}Can be according to concrete crossing Situation is different and adaptive change, is so conducive to more preferably guaranteeing that vehicle is not clashed at crossing, and then is conducive to into one The security that the raising crossing of step is passed through.

Optionally, in the application some possible embodiments, methods described also includes：In the control of the entrance lane xi System power phase place drives the Nxi horizontal ground traffic signal light group synchronously to send forbidden optical signal when terminating.Or away from institute The control phase place for stating entrance lane xi terminates also to remain when emptying phase place duration, drives described Nxi laterally traffic above-ground letter Signal lamp group synchronously sends forbidden optical signal.Or terminate also to remain in the control phase place away from the entrance lane xi and empty phase place duration When, drive described Nxi horizontal ground traffic signal light group to start to send out successively from the horizontal ground traffic signal light group qxi Go out forbidden optical signal, wherein, horizontal ground traffic signals described in the distance among the Nxi horizontal ground traffic signal light group The initial time that the nearer horizontal ground traffic signal light group of lamp group qxi sends forbidden optical signal is more early, and the horizontal ground is handed over Ventilating signal lamp group pxi sends the initial time of forbidden optical signal, is later than its in the Nxi horizontal ground traffic signal light group Its any one horizontal ground traffic signal light group sends the initial time of forbidden optical signal.

For example, the horizontal ground traffic signal light group pxi and horizontal ground traffic signal light group qxi sends forbidden Entrance boot section of the interval of the initial time of optical signal equal to the entrance lane xi empties duration.Wherein, the entrance car The entrance boot section of road xi empties duration and is expressed as T_{YD_qk_xi},Wherein, V'_{YD_qk_xi}Can Equal to V_{lk_max}Or V_{lk_min}Or V_{lk_q}, wherein, the V_{lk_max}Represent the Maximum speed limit of the grade crossing, V_{lk_min}Table Show the minimum speed limit of the grade crossing, V_{lk_q}Represent the desired speed of the grade crossing.Wherein, entrance guiding Area empties duration T_{YD_qk_xi}E.g., less than overlap duration T_{cd_xi}。V_{lk_min}Less than V_{lk_max}。V_{lk_q}Value space be greater than or wait In the V_{lk_min}And less than or equal to V_{lk_max}Any real number, i.e. V_{lk_q}More than or equal to the V_{lk_min}And be less than or equal to V_{lk_max}。

Concrete example, for powered Nxi horizontal ground traffic signal light group is by from horizontal ground traffic signals Lamp group qxi starts to send forbidden optical signal successively and presents the situation that at the uniform velocity guides speed, then, Nxi laterally ground hand over Horizontal ground traffic signal light group i in ventilating signal lamp group sends the initial time of forbidden optical signal, hands over relative to horizontal ground Ventilating signal lamp group qxi sends the interval duration of the initial time of forbidden optical signal and is expressed as T_{Δr_i_qxi}, wherein,L_{i_qxi}Represent the horizontal ground traffic signal light group i relative to institute The spacing of horizontal ground traffic signal light group qxi is stated, the horizontal ground traffic signal light group i is the Nxi laterally ground Any one horizontal ground traffic signal light group in traffic signal light group.

Optionally, in the application some possible embodiments, methods described also includes：

Terminate also to remain in the control phase place away from the entrance lane xi and empty when phase place duration adds excessive phase place duration, The Nxi horizontal ground traffic signal light group is driven synchronously to send alert traveling optical signal, in the control away from the entrance lane xi Power phase place terminates also to remain and empties when phase place duration adds excessive phase place duration, drives described Nxi laterally ground traffic signal light Group starts to send alert traveling optical signal successively from the horizontal ground traffic signal light group qxi, wherein, the Nxi horizontal ground Horizontal ground traffic signal light group qxi nearer horizontal ground traffic signal light group described in distance among traffic signal light group is sent out The initial time of responding traveling optical signal is more early, the horizontal ground traffic signal light group pxi send alert traveling optical signal it is initial when Carve, other any one the horizontal ground traffic signal light groups being later than in the Nxi horizontal ground traffic signal light group send The initial time of alert traveling optical signal.For example, the horizontal ground traffic signal light group pxi and the horizontal ground traffic signal light Group qxi sends entrance boot section of the interval of the initial time of alert traveling optical signal equal to the entrance lane xi and empties duration.

In actual applications, the executive agent of said method can be that the signal lamps such as semaphore, array driver drive control Control equipment.The semaphore referred in the embodiment of the present application is likely to referred to as programme-controlled exchange, or traffic control signal machine, traffic letter Number machine, intersection annunciator, crossing traffic semaphore or crossing traffic control signal machine etc..The exemplified letter of Fig. 6 and Fig. 7 Some possible annexations of number machine, array driver and crossroad traffic signal lamp array.Specifically, semaphore or array drive Dynamic device can be by working to crossroad traffic signal lamp array output drive signal come drive control crossroad traffic signal lamp array. In practical application, each horizontal ground traffic signal light group can work under the control of semaphore.Or each horizontal ground Traffic signal light group can work under the control of the array driver being connected with semaphore.

For example, due to entrance lane control phase place start/stop time (for example pass through phase place start/stop time, excessive phase The start/stop time of position or the start/stop time of forbidden phase place etc.) determined by semaphore, the start/stop time of these phase places can record In the multiphase traffic time allocation table that semaphore is safeguarded, therefore, when semaphore can learn the start-stop of control phase place of each entrance lane Carve, that is to say, that semaphore can learn that what moment is the upper crossing punching of the control phase place away from the entrance lane xi Prominent control phase place terminates also to remain overlap duration T_{cd_xi}When.And array driver then can from semaphore or (or with semaphore connect The other equipment for connecing or being controlled by semaphore) what moment is the control away from the entrance lane xi for direct or indirect learning The upper crossing conflict control power phase place of phase place terminates also to remain overlap duration T_{cd_xi}When.For example, array driver can Based on from semaphore (or the other equipment for being connected with semaphore or being controlled by semaphore) for current phase place or forbidden phase The countdown signal of position, learns that what moment is a upper crossing conflict control of the control phase place away from the entrance lane xi Power phase place terminates also to remain overlap duration T_{cd_xi}When.

Therefore, in some technical schemes of the embodiment of the present application, by introducing entrance boot section and crossing conflict control The overlap mechanism of system power phase place, when terminating also to remain overlap duration away from current control phase place, just can control current control phase The next crossing conflict control power phase place of position starts to let pass.It is next at the end of being so achieved that current control phase place also not Crossing conflict control power phase place has begun to, and realizes that crossing conflict control weighs the overlap of phase place, and then causes next crossing punching The vehicle of the corresponding entrance lane of prominent control phase place can in advance accelerate in entrance boot section, thus, when it reaches crossing Speed may be of a relatively high, therefore just can be shortened by the time of the grade crossing, and this mechanism can be by a relatively large margin Raising grade crossing vehicle pass-through efficiency, and then can for alleviate traffic congestion lay the foundation.

Also, because the horizontal ground traffic signal light group pxi and the horizontal ground traffic signal light group qxi send The time at intervals for allowing the optical signal of vehicle pass-through is equal to overlap duration, thus, the vehicle on entrance lane xi is at the Nxi Laterally the safety guiding of ground traffic signal light group is descending when sailing to crossing, before with the road of the control phase place of entrance lane xi Mouthful conflict a upper control phase place be over, be thus advantageous to cause entrance lane xi on vehicle crossing not with its He collides with each other the current vehicle of crossing conflict, and then the vehicle advantageously allowed on entrance lane xi runs over the safety at crossing Property is ensured.

Illustrate below by an instantiation.Assume that there is a north-south intersects with the plane cross that East and West direction is intersected Crossing, it is assumed that the total duration of the phase cycling of whole plane cross intersection is fixed as 120 seconds.Whole plane cross crossroad Mouthful a phase cycling for plane cross intersection all crossings conflict track control phase place (for example north-south is straight The control phase place of runway, north-south left turn lane, East and West direction Through Lane and East and West direction left turn lane) circulate one week. The set-up mode of the control phase place in each group crossing conflict track in traditional scheme can be as shown in Fig. 5-b citings, each group crossing Without temporal overlap between the control phase place in conflict track, when whole plane cross intersection phase cycling it is total Duration is assumed to be fixed as 120 seconds, then north-south Through Lane, north-south left turn lane, East and West direction Through Lane and thing be to the left The control phase place in this 4 groups of crossings conflict track of changing trains or buses typically is respectively 30 seconds.Assume the control of north-south left turn lane Phase place when a length of 30 seconds, in Fig. 5-b exemplified north-south left turn lane non-controlling power phase place be 0~90 second, in Fig. 5-b The control phase place of exemplified north-south left turn lane is 90~120 seconds.Wherein, the control phase place of north-south left turn lane Including current phase place (such as green light phase place) 25 seconds, transition phase place (such as amber light phase place) 3 seconds, empty phase place (the full red light in crossing Period) about 2 seconds.In the case, corresponding effectively current duration can be equal to current -2 seconds 25 seconds (2 seconds for deducting herein of phase place Driver's reaction time+vehicle launch time etc. is regarded as, current phase loss duration is can be described as)+available transition phase place Shi Changyue (assumes that transition phase place duration includes for 3 seconds in 1 second：About 1 second+not available transitional face of available transition phase place duration 2 seconds are about during position), about 24 seconds altogether.The total losses time of single control phase place is (when can claim the transition loss of control phase place It is long) 2 seconds are about when being equal to not available transition phase place duration about 2 seconds+empty phase place 2 seconds+current phase loss, that is to say, that The total losses time reaches about 6 seconds altogether.

After implementing application scheme, it is assumed that the overlap duration (i.e. preaceleration duration) of crossing conflict control power phase place is 8 seconds. Spacing between stop line and crossing safety line is adapted with Chong Die duration, and then is capable of achieving crossing conflict track (for example, north and south To Through Lane and East and West direction Through Lane) control phase place between Chong Die 8 seconds.The each group road arranged according to overlap mode The various phase places in mouth conflict track can be as shown in Fig. 5-c and Fig. 5-d citings.

In citing shown in Fig. 5-c, remained fixed at 120 seconds with the phase cycling total duration of whole plane cross intersection and be Example.

Wherein, in scene shown in Fig. 5-c citings, start because the control phase place of north-south left turn lane shifts to an earlier date 8 seconds, If its end time is constant, then the duration of its control phase place can (Fig. 5-c pass the imperial examinations at the provincial level illustration by extending within original 30 seconds 38 seconds The control phase place for going out north-south left turn lane is 0~82 second, the control phase of exemplified north-south left turn lane in Fig. 5-c Position is 82~120 seconds), therefore effectively current duration is equal to transition loss duration (the not available mistake of 38 seconds-control phase place 2 seconds+(crossing empties about 2 seconds+entrance boot section and empties about 1 second)+current phase loss that empties phase place about 3 seconds is about when crossing phase place Shi Changyue 2 seconds, about 7 seconds altogether), about 31 seconds altogether.North-south Through Lane, East and West direction Through Lane and East and West direction left turn lane Situation be similar to.

It can be seen that, in scene shown in Fig. 5-c citings, in the total duration of the phase cycling of whole plane cross intersection Under conditions of (120 seconds) are constant, the effectively current duration of the single control phase place of north-south left turn lane is relative to lift ((31- 24)/24) ≈ 29%, the increase of effectively current duration inevitably facilitates raising vehicle pass-through efficiency.

In illustrating shown in Fig. 5-d, with north-south Through Lane, north-south left turn lane, East and West direction Through Lane and east West turn left this 4 groups of crossings conflict track of track control phase place duration be fixed to 30 seconds as a example by, in such case Under, the overlap of phase place is weighed through crossing conflict control, as shown in Fig. 5-d citings, the lane of whole plane cross intersection Phase total duration shorten to 96 seconds by 120 seconds.

In scene shown in Fig. 5-d citings, in the total duration larger amplitude of the phase cycling of whole plane cross intersection Degree shorten (shortening to 96 seconds by 120 seconds) in the case of, due to north-south Through Lane, north-south left turn lane, East and West direction it is straight The duration of the control phase place in runway and this 4 groups of crossings conflict track of East and West direction left turn lane does not all shorten, therefore accordingly The effectively current duration of control phase place does not shorten.Because the total duration of the phase cycling of whole plane cross intersection shortens , then the lane of the whole plane cross intersection that can be arranged in same duration scope (such as within an hour) Issue amount can be with a larger increase, and the corresponding effectively current duration of so same duration scope also will necessarily increase, when effectively passing through Long increase inevitably facilitates raising vehicle pass-through efficiency.It can be seen that, some technical schemes of the embodiment of the present application are not shortening list On the basis of the effectively current duration of individual control phase place, plane cross intersection phase cycling can be using total duration relatively more The short minor cycle, so advantageously account for people and plane cross intersection large period is denounced, because in traditional scheme, being The transition loss duration for reducing control phase place accounts for the proportion of control phase place duration, and the means for generally adopting are by plane ten The total duration of the phase cycling of word intersection arranges very long, the single lane of such as some plane cross intersections The total duration of phase is even up to 240 seconds, and this causes the time of the red lights such as pedestrian and vehicle all very long, this to wait red light duration to have When challenged people's tolerance limit, cause extensively to be denounced by people.

It is (i.e. pre- with the overlap duration of time upper adjacent crossing conflict control power phase place in citing shown in Fig. 5-c and Fig. 5-d Accelerate duration) to illustrate as a example by 8 seconds, overlap duration and be alternatively other durations certainly, for example can be 1 second, 2 seconds, 3.5 seconds, 5 seconds Or 6 seconds, 8 seconds, 9 seconds, 10 seconds or less than other durations of corresponding control phase place duration, corresponding embodiment can be by that analogy. Illustrate so that control phase place includes current phase place, transition phase place and empties phase place as an example in citing shown in Fig. 5-c and Fig. 5-d, Certainly, control phase place is also likely to be other composition forms illustrated in Fig. 2-c, and such as control phase place may include current phase Position and empty phase place, but do not include transition phase place.Control phase place is that the corresponding embodiment of other composition forms can be with such Push away.

As a whole, the scheme of the embodiment of the present application is implemented, can be in the phase cycling of whole plane cross intersection Total duration is relative on the premise of immobilizing to lift effectively current duration, or can also be constant in single control phase place duration On the premise of shorten the phase cycling total duration of whole plane cross intersection.Phase place is weighed by introducing crossing conflict control Overlap mechanism and entrance boot section, not only contribute to offset the transition loss duration of control phase place, and are conducive to significantly carrying The speed that high vehicle passes through crossing.It can be seen from time=distance/speed, speed is faster within the identical time, then pass through Vehicle is also more, and traffic efficiency is also higher.The technical scheme of the embodiment of the present application with by take prolongation phase cycling it is total Duration is compared come some traditional schemes for reducing the transition loss duration proportion of control phase place, not only can significantly reduce whole flat The phase cycling total duration of face right-angled intersection, and relatively the red light stand-by period is shortened, advantageously reduce fuel oil and disappear Consumption and discharge amount of exhaust gas.

As an example it is assumed that daily will be through 5 plane cross intersections by each car, it is assumed that each plane cross is handed over Cross road mouth waits less 30 seconds red lights, and the average 1 liter of gasoline per hour of fuel consumption is calculating during idling, then with 1,000,000, certain city Car is calculated, and the fuel oil of more than one hundred million units can be saved every year.For example, (5*0.5 minutes * 1 liter/60 minutes) * 360 days * 100 ten thousand= 15000000 liters.Assume that per liter of oil, by 7 yuan of calculating, can save every year 15000000 liters of * 7 yuan=105,000,000 yuan of oil.This is just improving logical Social resources have been saved while line efficiency.

Further, implement the engineered of the embodiment of the present application scheme to be easier, original means of transportation also can be basic Retain, such as original facilities such as sensing of taking pictures can be continuing with substantially.Mainly adjust each group crossing conflict control power phase place Start/stop time, the safe line position in crossing will be arranged in prior art, and (such as horizontal ground traffic signal light group pxi's sets Seated position) stop line carry out after move so that crossing safety line and stop line be (such as horizontal ground traffic signal light group qxi's Set location) separate on locus, the region between stop line and crossing safety line forms entrance boot section.Further , because stop line is relatively distant from crossing, then just basic without worrying to have pedestrian from people's row horizontal stroke again during vehicle start Road is popped out and, and also need not again worry that having the vehicle for making a dash across the red light to knock comes when pedestrian goes across the road substantially, so to a certain degree On realize people's car separation without mutual interference.

Further, because in the conventional technology, the phase cycling total duration of grade crossing is generally all very long, leads Cause the stand-by period also very long, and the duration of single control phase place is also longer.When the distance between two grade crossings When closer, easily cause vehicle to be detained in crossing, can thus affect corresponding next one control phase place to be let pass Vehicle, so as to cause congestion to occur, is commonly called as rushing green light by crossing.It is former that the big traffic congestion of traffic in misty rain day is also due to this mostly Because caused.After implementing some technical schemes of the application, due to being conducive to the phase cycling for shortening grade crossing total Duration, thus advantageously reduces and rushes green light phenomenon.Meanwhile, grade crossing phase cycling total duration significantly shortens, and can make The relative reduction of public transit vehicle that single phase cycling is let pass, advantageously reduces the public train phenomenon of bus platform.
