Wherein, the Parking Entrance of grade crossing can also be referred to as entrance driveway.One Parking Entrance of grade crossing It may include one or more entrance lane, 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 can also claim For downstream track.In the relevant drawings of the embodiment of the present application mainly so that Parking Entrance is located on the right side of corresponding exit ramp 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 Parking Entrance X left-hand rotation entrance lane, and left-hand rotation entrance lane can abbreviation left turn lane.Assuming 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 Parking Entrance X straight trip Entrance lane, straight trip entrance lane can abbreviation Through Lane.Assuming that 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 Parking Entrance X right-hand rotation entrance lane, 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.Certain some grade crossings enter The quantity of mouth road and exit ramp may also be unequal, and for example certain cruciform plan intersection may also only include 3 Parking Entrances With 4 exit ramps.
In some cases, the guiding of some entrance lanes is probably 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 entrance lane of specific such as certain Parking Entrance rightmost 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. south 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, in the case where there is some scenes, and 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, i.e., by stop line and crossing safety line United two into one on locus.And in the embodiment of the present application, mainly with the travel direction relative to entrance lane, the entrance car The stop line in road is inquired into exemplified by being arranged on after the crossing safety line of the entrance lane, 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 entrance lane, it is audacious by entrance lane Stop line and crossing safety line are separated on locus, crossing safety of the stop line relative to the entrance lane of entrance lane Moved after line, and then form 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 of entrance lane and the stop line of the entrance lane can be relatively fixed, when So, it the factor such as can also 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 (to be permitted Perhaps row can referred to as be permitted by passing through) or no through traffic (no through traffic can be referred to as forbidden) or warning is passed through and (warns current 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 allows or alert row Or it is forbidden.Wherein, the current phase that the phase for controlling the vehicle on the entrance lane to let pass can be referred to as the entrance lane is (logical Line phase is alternatively referred to as clearance phase or fair line phase), by corresponding traffic lights send optical signal in conventional art Color is green during current phase, and therefore, in the conventional technology, current phase is also commonly referred to as green light phase, this Shen Please be in the technical scheme of embodiment, the color that corresponding traffic lights send optical signal during current phase is not limited to green Color, and can be can be used to indicate that any solid color or several colors that allow vehicle pass-through are combined by expanding, phase of passing through Period corresponding traffic lights send the color of optical signal to be implemented for one kind in green simply the embodiment of the present application is optional Mode.The phase of Pedestrian Zone At any time on control entrance lane can then be referred to as the forbidden phase of the entrance lane, in tradition In technology, by the color that corresponding traffic lights send optical signal is red, therefore conventional art during forbidden phase In forbidden phase be typically also referred to as in red light phase, the embodiment of the present application the corresponding traffic lights institute during forbidden phase The color for sending optical signal is not limited to red, and can be can be used to indicate that no thoroughfare for vehicles by expanding it is any single It is red simply this Shen that corresponding traffic lights, which send the color of optical signal, during color or the combination of several colors, forbidden phase A kind of optional embodiment that please be in embodiment.Similar, the phase of vehicle police's row on control entrance lane can be referred to as For police's line phase (alert line phase can also claim transition phase) of the entrance lane, by corresponding traffic lights institute in conventional art It is that alert line phase is typically also referred to as Huang in yellow, therefore conventional art during alert line phase to send the color of optical signal The color that corresponding traffic lights send optical signal during alert line phase in lamp phase, the embodiment of the present application is not limited to Huang Color, and any solid color or the color combination of warning vehicle pass-through can be can be used to indicate that by expanding, alert line phase It is a kind of optional embodiment party in the embodiment of the present application that period corresponding traffic lights, which send the color of optical signal for yellow, Formula.
Illustrate, " phase " mentioned in certain some traffic specification typically acquiescence is for phase (such as green light that passes through Phase), i.e., it is that current phase (such as green light phase) is referred to as phase in certain some traffic specification, in these traffic specifications even Forbidden phase and transition phase 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 comparatively become more meticulous, therefore especially these three different phases of current phase, forbidden phase and the transition phase of differentiation Concept.
In general, continuously current phase, transition phase and the forbidden phase of certain entrance lane can form the entrance The single phase cycling in track, the total duration of two neighboring phase cycling can fix (shown entrance lane of being illustrated in such as 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 illustrating Fig. 2-a The total duration of adjacent two phase cyclings).The phase cycling of two entrance lanes of the identical guiding of same Parking Entrance is set May be identical (phase cycling of two left turn lanes of the Parking Entrance Y as shown in illustrating Fig. 2-b is identical) or different.Same entrance The phase cycling of different two entrance lanes being oriented in road is set may be identical or different.Have under some scenes, transition phase It can even is that in this case, phase cycling does not only include current phase and forbidden phase, without including 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, represent wagon flow on this two entrance lanes exist by the driving trace at crossing and intersect (or In the presence of intertexture), i.e., the wagon flow on any two entrance lanes in the track of crossing conflict each other exists by the driving trace at crossing 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 Wagon flow on Through Lane exists by the driving trace at crossing intersects, such as shown in Fig. 1-c citings, head west Through Lane and south If the wagon flow on row Through Lane is simultaneously by 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.
It is set forth below the concept of " crossing conflict pass through phase ", conflict phase of passing through in crossing is also relative concept.It is simple next Say, the current phase of current phase 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 transition phase 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 can referred to as conflict current phase.Crossing conflict transition phase can referred to as conflict transition phase.
The concept of " control phase " and " non-controlling power phase " is set forth below, the control phase 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 (if present) or current phase, are led to Often need the regular hour to cross crossing, in order to avoid these vehicles from another crossing track that conflicts with driving into the vehicle at crossing In crossing conflict, therefore, being proposed in some traffic specifications generally need to be to time of 2 seconds or so to ensure in transition phase (if depositing ) or current phase end these vehicles of stop line for just crossing can safety cross crossing, in some traffic specifications By this section be used for time for emptying be referred to as to empty phase (wherein, empty phase be similar to it is alleged in some traffic specifications Crossing full red signal interval).In general, on a timeline, the control phase of certain entrance lane+non-controlling power phase=this enters Current phase+forbidden phase+transition phase the (if present) in mouth track.Forbidden phase may include to empty phase and non-clear phase Position.Certainly empty phase it is some in particular cases may also be not necessarily, when empty phase it is non-existent in the case of, it is forbidden Phase can be equal to non-controlling power phase, that is to say, that the non-controlling power phase of entrance lane is the forbidden of the entrance lane Phase it is part or all of.In the case of it there is transition phase and empty phase, control phase may include current phase, mistake Cross phase and empty phase.In the case of it there is transition phase without existing and emptying phase, control phase includes current phase Position and transition phase.When in the absence of transition phase but in the case of existing and emptying phase, control phase include current phase and Empty phase.When in the absence of transition phase and in the case of emptying phase, control phase can be equal to current phase.For example, The control phase of exemplified certain entrance lane of Fig. 2-c (such as entrance lane x05) includes current phase, transition phase and clear Kongxiang position；Or the control phase of certain entrance lane (such as entrance lane x07) may include current phase and empty phase；Or The control phase of certain entrance lane (such as entrance lane x06) includes current phase and transition phase；Or certain entrance car The control phase in road (such as entrance lane x08) can be equal to current phase.The phase mentioned in some traffic specifications also may be used Control phase can be defaulted as, i.e., is probably by control phase referred to as phase in these traffic specifications.
The concept of " crossing conflict control weighs phase " is set forth below, conflict control power phase in crossing is relative concept, simply For, crossing conflict control weighs phase to the control phase of two entrance lanes in the track of crossing conflict each other each other.Crossing is rushed Prominent control phase can abbreviation conflict control power phase.
What the description above for each conception of species (such as " phase " concept) was mainly carried out exemplified by for track.And pin Some concepts (such as some " phase " concepts) to 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 (entrance lane, the exit lane of such as grade crossing) etc..Wherein, the object passed through on walkway Referred to as passed through object (current object is probably pedestrian or vehicle etc.), and the object data stream passed through on walkway is referred to as to pass through 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..Such as the object passed through on track may include vehicle, the object data stream passed through on track includes car Stream etc..
For the scene of crossing, current phase, transition phase and forbidden phase of crossing etc. also may be present general Read, the concepts such as the control phase and non-controlling power phase of crossing also may be present.Between crossing and some tracks It 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 Seen in justice, when two walkways (the two walkways may all be track, or may also one of them be track, it is and another Individual is crossing) current stream travel track exist intersect, then the two walkways can mutually be referred to as conflict road, mutually Passed through for the current stream on two walkways in the road that conflicts within the identical period, 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 is alternatively referred to as conflict Track；If the conflict road of certain walkway is crossing, this conflict road is alternatively referred to as the crossing that conflicts.Track and track Between may conflict each other, and may also 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) in (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 are sent 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 vehicle pass-through in the row track during sending fair traveling optical signal, the traffic lights of certain crossing send fair row light letter 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 The vehicle pass-through in the track, the traffic lights of certain crossing is warned to be warned during sending 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 specific 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 red of flicker The red light signal of optical signal and/or nand flash.Wherein, the red light signal of nand flash 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 (such as vehicles or pedestrians Deng) current optical signal, therefore any one can be used to indicate that current object (such as vehicles or pedestrians for forbidding corresponding walkway 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 can also combine the optical signal of several colors according to certain rule forbid corresponding walkway with instruction current pair As current, then the optical signal of these forms of expression is also regarded as forbidden optical signal.
In another example, fair traveling optical signal can be green light signal, green light signal that green light signal concretely flashes and/ Or the green light signal of nand flash.The green light signal of nand flash 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, which can be used to indicate that, allows the current object (such as vehicles or pedestrians) of corresponding walkway Current optical signal is considered as permitting traveling optical signal, then permit the form of expression of traveling optical signal to be not limited to the example above, example As that 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.
In another example, alert traveling optical signal can be yellow optical signal, yellow optical signal that yellow optical signal concretely flashes and/ Or the yellow optical signal of nand flash.The yellow optical signal of nand flash 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 Passed through as also the optical signal of several colors can combine according to certain rule for the current object of instruction warning, then The optical signal of these forms of expression is also regarded as warning traveling optical signal.
Generally speaking, fair traveling optical signal may have one or more kinds of forms of expression, and forbidden optical signal can also be present One or more forms of expression may be present in one or more forms of expression, alert traveling optical signal.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 can also claim For excessive optical signal), indicate current object fair row and it is forbidden between transition.If in some cases without such transition, So may also be just without 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 can be sent but can not The signal lamp for sending A2 classes optical signal and A3 class optical signals can be described as " A1 classes signal lamp ".A2 classes optical signal can be sent but can not The signal lamp for enough sending A1 classes optical signal and A3 class optical signals is properly termed as " A2 classes signal lamp ".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 classes signal lamp ".A1 classes light letter can be sent Number and A2 classes optical signal but the signal lamps of A3 class optical signals can not be sent can be described as " A12 classes signal lamp ".A1 classes can be sent Optical signal and A3 classes optical signal but it the signal lamps of A2 class optical signals can not be sent can be described as " A13 classes signal lamp ".It can send A2 classes optical signal and A3 classes optical signal but the signal lamps of A1 class optical signals can not be sent it is properly termed as " A23 classes signal lamp ".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.
Simple introduction has been done to some related notions that the embodiment of the present application scheme may relate to above.
, can be on the part or all of entrance lane of grade crossing in some technical schemes of the embodiment of the present application 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 similar.More detailed citing introduction is carried out 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, described Nxi horizontal ground traffic signal light group includes being arranged at The horizontal ground traffic signal light group pxi of the entrance lane xi of the grade crossing safe line position in crossing.Described Nxi horizontal Earthward traffic signal light group also includes the horizontal ground traffic signal light for the parking line position for being arranged at the entrance lane xi Group qxi.
Wherein, the roadway segment formation entrance boot section delimited between the crossing safety line and stop line of entrance lane, entrance Also entrance boot section is regarded as in boot section.For example, between entrance lane xi crossing safety line and entrance lane xi stop line The roadway segment formation entrance lane xi of delimitation entrance boot section (entrance lane xi entrance boot section).
Wherein, any two ground traffic signal light group in described 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.Described 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 two signal lamp).
For example, Nxi can for example be equal to 2,3,5,7,8,10,11,29,36,50,100 or other values.
Wherein, at least one (such as 1 or at least two) in horizontal ground traffic signal light group i is driven with wireless type Dynamic signal input port and/or wired driving signal input mouthful.The horizontal ground traffic signal light group i is the Nxi One of 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 described 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. In another example, it is more remote apart from the horizontal ground traffic signal light group pxi in described Nxi horizontal ground traffic signal light group Spacing between two adjacent transverse ground traffic signal light groups it is smaller (i.e. in entrance lane xi travel direction, 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 horizontal ground traffic signal light group described in person, two phases more remote apart from the horizontal ground traffic signal light group pxi Spacing between the traffic signal light group of adjacent transverse direction ground it is smaller (i.e. in entrance lane xi travel direction, the Nxi transverse direction The spacing between two adjacent transverse ground traffic signal light groups in ground traffic signal light group is gradually reduced).Certainly, it is described Spacing between Nxi horizontal ground two adjacent transverse ground traffic signal light groups of traffic signal light group is also likely to be random change Changing rules change or other, and not necessarily show the change for being gradually reduced or gradually increasing along certain direction of the example above Rule.
For example, it is not only arranged at two neighboring in Nxi horizontal ground traffic signal light group of entrance boot section Spacing can be equal between horizontal ground traffic signal light group, and adjacent in described 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 ".In another example under some scenes, being arranged at entrance boot section Nxi horizontal ground traffic signal light group in two neighboring horizontal ground traffic signal light group between spacing can be equal, But the two neighboring horizontal ground traffic signal light group in described 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 not waiting equidistantly Formula ".In another example, have under some scenes, be arranged at adjacent two in Nxi horizontal ground traffic signal light group of entrance boot section Spacing between individual horizontal ground traffic signal light group is unequal, but the phase in described Nxi horizontal ground traffic signal light group Adjacent two horizontal ground traffic signal light group sends 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 " not equidistant pattern when waiting ", equidistantly isochronous mode can be not by that analogy.
Specifically for example, it is assumed that Nxi is equal to 11, entrance lane xi entrance guiding section length is 10 meters, then Nxi laterally Ground traffic signal light group can uniformly branch be between entrance lane xi crossing safety line and stop line, such as in entrance car One horizontal ground traffic signal light group, Nxi horizontal ground traffic signal light are set in road xi entrance boot section every 1 meter Entrance lane xi entrance boot section 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 groups of arbitrary neighborhood two send fair traveling optical signal (or forbidden light Signal or alert traveling optical signal) initial time interval can equal (such as 0.2 second, 1 second, 1.5 seconds or 2 seconds) or.And example Such as assume that Nxi is equal to 6, entrance lane xi entrance guiding section length is 10 meters, then Nxi horizontal ground traffic signal light group Can uniformly branch is between entrance lane xi crossing safety line and stop line, such as the entrance boot section in entrance lane xi In a horizontal ground traffic signal light group is set every 2 meters, Nxi transverse direction ground traffic signal light group can be by entrance lane xi The spacing that is divided between 5 entrance lanes section, two horizontal ground traffic signal light groups of arbitrary neighborhood of entrance boot section be 2 Two horizontal ground traffic signal light groups of rice arbitrary neighborhood send fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) The interval of initial time can be equal or different.Wherein, the two neighboring transverse direction in described Nxi horizontal ground traffic signal light group Other equal set-up modes of spacing can be by that analogy between ground traffic signal light group.
Wherein, when 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 among ventilating signal lamp group i share identical drive signal, 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 be lighted or be closed simultaneously simultaneously, because these are believed 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 understood that as above-mentioned Vj1_j2Equal to Vj2_j3, then horizontal ground traffic signal light group j1 can be represented, described The horizontal ground traffic signal light group j2 and horizontal ground traffic signal light group j3 by send successively fair traveling optical signal (or prohibit Traveling optical signal or alert traveling optical signal) the guiding speed that is showed is at the uniform velocity.And as above-mentioned Vj1_j2Less than above-mentioned Vj2_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 showed 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 show and at the uniform velocity guide speed, can also show even acceleration or non-even acceleration Speed change guiding speed, be so advantageous for vehicle entrance boot section travel speed safely guide.
For example, when horizontal ground traffic signal light group qxi sends fair traveling optical signal, representing current allows entrance lane Vehicle on xi, which crosses horizontal ground traffic signal light group qxi, (allows the vehicle on entrance lane xi to cross entrance lane xi Stop line), vehicle (being for example stopped at the head car after horizontal ground traffic signal light group qxi) drive into entrance boot section it Afterwards, other horizontal ground in Nxi horizontal ground traffic signal light group in addition to horizontal ground traffic signal light group pxi are handed over Under the guiding for the fair traveling optical signal that ventilating signal lamp group is sent 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, vehicle in horizontal ground traffic signal light group pxi afterwards Horizontal ground traffic signal light group pxi (that is, the crossing safety line for crossing entrance lane xi) is crossed, vehicle is crossing horizontal ground Just enter crossing after traffic signal light group pxi or enter crossing 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 showed (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 more than respective guide speed travel speed in entrance to draw Lead area's traveling, then, vehicle is just likely to " making a dash across the red light " phenomenon occur, that is, is likely to vehicle occur on some horizontal ground (wherein, this horizontal ground traffic signal light group is sending fair traveling optical signal before traffic signal light group sends 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 using Nxi horizontal ground traffic signal light group to car Travel speed in entrance boot section is guided safely, and then is advantageously allowed vehicle and driven into crossing with 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 Apply for the scheme of embodiment, be 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 Any one crossroad traffic signal lamp array that array can for example be provided such as above-mentioned embodiment.Specific such as crossroad traffic signal lamp Array includes Nxi horizontal ground traffic signal light group；Described Nxi horizontal ground traffic signal light group includes being arranged at plane The horizontal ground traffic signal light group pxi of the entrance lane xi of the intersection safe line position in crossing, the Nxi laterally Face traffic signal light group also includes the horizontal ground traffic signal light group for the parking line position for being arranged at the entrance lane xi qxi.Each horizontal ground traffic signal light group in described Nxi horizontal ground traffic signal light group includes at least one (for example 1 or at least two) signal lamp.Part or all of signal lamp among horizontal ground traffic signal light group i has wireless type drive Dynamic signal input port and/or wired driving signal input mouthful.The horizontal ground traffic signal light group i is the Nxi One of horizontal ground traffic signal light group or any one horizontal ground among individual horizontal ground traffic signal light group are 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 of system power phase terminates also to remain overlapping duration Tcd_xiWhen, drive described Nxi laterally Face traffic signal light group sends fair traveling optical signal successively since the horizontal ground traffic signal light group qxi.Described Nxi horizontal Earthward transverse direction horizontal ground traffic signals nearer ground traffic signal light group qxi described in the distance among traffic signal light group Lamp group is driven the initial time for sending fair traveling optical signal more early, and the horizontal ground traffic signal light group pxi, which is driven, to be sent Permit the initial time of traveling optical signal, be later than in the Nxi transverse direction ground traffic signal light group it is other any one laterally Face traffic signal light group is sent the initial time of fair traveling optical signal by driving.Can for example detection (directly or indirectly detection) be passed through The upper crossing conflict control of the control phase of the entrance lane xi weighs the progress of phase, when is entrance car to learn The upper crossing conflict control power phase of road xi control phase terminates also to remain overlapping duration Tcd_xiWhen.
It is to be appreciated that the corresponding overlapping duration 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 travel direction of approximately the same plane intersection is identical but is oriented to different entrance lanes The corresponding possible equal or part of overlapping duration is equal or is not mutually equal.The travel direction and guiding of approximately the same plane intersection The possible equal or part of the corresponding overlapping duration of entrance lane of all same is equal or is not mutually equal.It is appreciated that overlapping duration Tcd_xiFor the corresponding overlapping durations of entrance lane xi, entrance lane xi is one of entrance lane of grade crossing or appointed One entrance lane of meaning.
It is the upper crossing punching that the horizontal ground traffic signal light group pxi, which sends the initial time of fair traveling optical signal, Prominent control phase finish time.That is, described horizontal ground traffic signal light group pxi and transverse direction ground traffic signal light group qxi Send the interval T of the initial time of fair traveling optical signalΔ_pxi_qxiEqual to overlapping duration Tcd_xi.Overlapping duration Tcd_xiCan be storage Preset value (can update currently stored T according to the overlapping duration more new command from upper equipment or Man Machine Interfacecd_xi) Or overlapping duration Tcd_xiIt can in real time be calculated and obtained based on preset algorithm.Such as overlapping duration Tcd_xiCan 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 of phase for example may be the southern row Through Lane or northern row of the grade crossing The control phase of Through Lane or head west left turn lane or northern row left turn lane because, grade crossing it is eastbound straight Runway, southern row Through Lane or northern row Through Lane or head west left turn lane or a northern row left side with the grade crossing Conflict track each other 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 upper crossing conflict control power phase for example may be the grade crossing southern row straight traffic The control phase 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 or northern row Through Lane of the grade crossing or eastbound left turn lane or southern row Conflict track each other 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 of East and West direction Through Lane are circulated.Wherein, upper one of the control phase of north-south left turn lane Conflict control power phase in crossing is the control phase of East and West direction left turn lane, the control phase of East and West direction left turn lane it is upper One crossing conflict control power phase is the control phase of north-south Through Lane, the control phase of north-south Through Lane Upper crossing conflict control power phase be East and West direction Through Lane control phase.In scene shown in Fig. 5-a citings, Assuming that the entrance lane xi is some 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 of phase is the control phase of East and West direction left turn lane, and the entrance lane is assumed again Xi is some entrance lane in East and West direction left turn lane, then a upper crossing for the control phase of the entrance lane xi Conflict control power phase is the control phase of north-south Through Lane, by that analogy.
In scene shown in Fig. 5-a citings, north-south left turn lane is overlapping with the control phase of East and West direction left turn lane Shi Changwei Tcd_3.A length of T when East and West direction left turn lane is overlapping with the control phase of north-south Through Lanecd_2.North-south is straight A length of T when runway is overlapping with the control phase of East and West direction Through Lanecd_1.The control phase of East and West direction Through Lane A length of T when overlapping with the control phase of north-south left turn lanecd_4.Wherein, Tcd_1、Tcd_2、Tcd_2And Tcd_4Can whole phases Deng or part it is equal or be not mutually equal.
As can be seen that because the roadway segment delimited between entrance lane xi crossing safety line and stop line can form entrance Boot section, this just provides certain space basis for vehicle by the advance acceleration at crossing, and drives into crossing for 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 to have had certain space basis.Hand on such as Nxi horizontal ground 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 gone out so that the speed that transport condition and vehicle to vehicle in entrance boot section roll entrance boot section away from is carried out more Accurate control becomes had possible, therefore, is so conducive to improving the safely controllable property of the vehicle pass-through of 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 controlling Nxi horizontal ground traffic signals When each horizontal ground traffic signal light group in lamp group sends the starting of fair traveling optical signal or alert traveling optical signal or forbidden optical signal Carve, be advantageously implemented the relatively accurate control by time during crossing and speed to vehicle, and then be conducive to further improving flat The vehicle pass-through safely controllable property of face intersection.For example when a upper crossing for the control phase of the entrance lane xi is rushed When prominent control phase terminates also to remain corresponding overlapping 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 horizontal ground traffic signal light group it In the nearer ground traffic signal light group qxi horizontal ground traffic signal light group of distance transverse direction, 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 laid 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 for the guiding speed that the optical signal sent is showed Crossing is crossed beneficial to vehicle is made in safely controllable efficient mode.
It is understood that in actual applications, powered described Nxi horizontal ground traffic signal light group is from described Horizontal ground traffic signal light group qxi starts to send fair traveling optical signal successively, can show at the uniform velocity guiding 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 by from horizontal ground traffic signals Lamp group qxi starts to send fair traveling optical signal successively and shows the situation that at the uniform velocity guides speed, then, Nxi horizontal ground friendship Horizontal ground traffic signal light group i in ventilating signal lamp group sends the initial time of fair traveling optical signal, is handed over relative to horizontal ground The interval duration that ventilating signal lamp group qxi sends the initial time of fair traveling optical signal is expressed as TΔg_i_qxi, wherein,
In another example, for powered Nxi horizontal ground traffic signal light group by from horizontal ground traffic signal light Group qxi starts to send fair traveling optical signal successively and show 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 transverse direction The interval duration that ground traffic signal light group qxi sends the initial time of fair traveling optical signal is expressed as TΔg_i_qxi, wherein,As the even initial velocity v for accelerating to guide speed0Universal expression during more than 0 Formula can be：
Wherein, the Tcd_xiRepresent the corresponding overlapping durations of entrance lane xi, Tcd_xiIt 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 transverse direction ground traffic signal light group qxi.It is described LYD_xiRepresent spacing (the i.e. entrance guiding head of district of entrance lane xi between entrance lane xi stop line and crossing safety line Degree), the LYD_xiIt is also equal to the spacing between horizontal ground traffic signal light group pxi and transverse direction ground traffic signal light group qxi. The Li_qxiThe spacing between transverse direction ground traffic signal light group i and transverse direction ground traffic signal light group qxi is represented, it is described Li_qxiIt is also equal to the spacing between horizontal ground traffic signal light group i and entrance lane xi stop line.Wherein, horizontal ground is handed over Ventilating signal lamp group i is any one horizontal ground traffic signal light group in Nxi horizontal ground traffic signal light group.
Wherein, LYD_xiAnd/or Tcd_xiValue can immobilize, can be also varied from environmental change.Generally come Say, for the consideration of secure context, the first car after entrance lane xi stop line drives into the speed most benefit at crossing 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, which is advantageously reduced, road occurs The probability of mouth accident.For the consideration of these secure contexts, permitting that described Nxi horizontal ground traffic signal light group is sent is utilized The guiding speed that traveling optical signal is showed, the travel speed that first car is driven into crossing is guided to safe range, then Crossing security is just more secure.
Such as common vehicle from the duration started to needed for accelerating to safe speed be exactly to obtainReference basis, Common vehicle from the distance started to needed for accelerating to safe speed be exactly to obtainReference basis.Represent into The plan initial value of the corresponding overlapping durations of mouth track xi,Represent that the plan of entrance lane xi entrance guiding section length is used Initial value.
Wherein, LYD_xiValue is equal toTcd_xiValue is equal toOr for LYD_xiAnd/or Tcd_xiValue 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 Corresponding safety coefficient is selected in the change of border factor, and then is based onWith currently selected peace Overall coefficient obtains currently used Tcd_xi(or LYD_xi) value.
The value that μ 1 (or μ 2) value can be equal to 1, μ 1 (or μ 2) is also greater than 1 or less than 1.μ 1 (or μ 2) value example Weather, light intensity, the gradient and/or crossing complexity environmental factor is such as may be referred 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 value), when the rainy day μ 1 (or μ 2) value (such as 1.2, 1.3rd, 1.5,2 or other values) be more than when fine day μ 1 (or μ 2) value.In another example when light intensity is preferable μ 1 (or μ 2) value 1 can be equal to or close to 1 (such as 1.1 or 1.05 or other value), when light intensity is poor μ 1 (or μ 2) value (such as 1.2, 1.3rd, 1.5,2 or other values) be more than when light intensity is preferable μ 1 value.In another example, μ 1 (or μ 2) value when the gradient is smaller 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 smaller is (for example 1.2nd, 1.3,1.5,1.8,2 or other values) be more than the value of μ 1 when the gradient is larger.The μ 1 for example when crossing complexity is smaller The value of (or μ 2) is equal to 1 or close to 1 (such as 1.1,1.04,1.08 or other value), 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) be more than μ 1 (or μ 2) when the gradient is smaller Value.
It is appreciated that the first purpose for setting μ 1 (or μ 2) is to improve security, therefore μ 1 (or μ 2) value is also possible to Determined with reference to the factor of other one or more influence safety.With specific reference to the factor of which influence safety, how with reference to shadow Ring each factor of safety to determine μ 1 (or μ 2) value, can be selected according to concrete scene needs, is 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 LYD_xiBetween can have corresponding relation.For example, the corresponding parking line position of peak hours/period can be pre-set (for example This period LYD_xiFor 10 meters or other values), corresponding parking line position (the such period L of half peak hours/periodYD_xiFor 8 meters), it is idle Period corresponding parking line position (such as this period LYD_xiFor 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 delimit be idle period, by other periods delimit be half peak hours/period, certainly correspondence not May also there are other Time segments division modes with application scenarios, no longer illustrate one by one herein.
Again for example, corresponding relation, i.e. different periods can are guided with entrance between vehicle flowrate and parking line position Section length LYD_xiBetween can have corresponding relation.The L for example when the vehicle flowrate at crossing is more than 100 per minuteYD_xiFor 10 meters or Other values, the entrance guiding section length L when the vehicle flowrate at crossing is 60~100 per minuteYD_xiFor 8 meters or other values.Work as road Entrance guiding section length L when the vehicle flowrate of mouth is less than 30 per minuteYD_xiFor 6 meters or other values, other situations are by that analogy.
In addition, the size of grade crossing, can also have between corresponding overlapping time and entrance guiding section length pair It should be related to, such as relatively large grade crossing, overlapping time and entrance guiding section length can be relatively large.And relatively Small grade crossing, overlapping time and entrance guiding section length can be relatively small.
When control phase includes emptying phase, current some traffic specifications regulation empties phase, 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 different tracks of approximately the same plane intersection empty length and may also be not quite similar, and empty a length of particular value during phase Might not be most scientific.It therefore, it can consider to obtain corresponding emptying phase duration T according to the length that empties in trackqk.Example Such asOr work asDuring more than or equal to 2 secondsAnd work as T during less than 2 secondsqk_xiValue is 2 seconds.Tqk_xiRepresent that entrance lane xi's empties phase duration.Lqk_xiRepresent xi pairs of entrance lane That answers empties length (Lqk_xiThe corresponding crossing length of entrance guiding section length+entrance lane xi equal to entrance lane xi). V'lk_xiFor example equal to the minimum speed limit V of the affiliated grade crossings of entrance lane xilk_minOr desired speed Vlk_q.Or V'lk_xi V can be equal tolk_min* μ 3 or Vlk_q* μ 3, the 3rd safety coefficient μ 3 value can be equal to 1 or more than 1 or less than 1.Specifically, μ 3 Value environmental factor such as may be referred to weather, light intensity, the gradient and/or crossing complexity determines, μ 3 specific value side Formula refers to μ 1 specific value mode.
Based on T obtained from the mode of the example aboveqk_xiIt can not be fixed duration 2 seconds, Tqk_xiCan be according to specific crossing Situation is different and the change of adaptability, is so conducive to more preferably ensuring that vehicle is not clashed at crossing, and then be conducive 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 drives described Nxi horizontal ground traffic signal light group synchronously to send forbidden optical signal when terminating.Or away from institute The control phase for stating entrance lane xi terminates also to remain when emptying phase duration, drives described Nxi horizontal traffic above-ground letter Signal lamp group synchronously sends forbidden optical signal.Or terminate also to remain in the control phase away from the entrance lane xi and empty phase duration When, drive described Nxi horizontal ground traffic signal light group to be sent out successively since the horizontal ground traffic signal light group qxi Go out forbidden optical signal, wherein, horizontal ground traffic signals described in the distance among described Nxi horizontal ground traffic signal light group The initial time that horizontal ground traffic signal light group nearer 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 described 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 sends forbidden with the horizontal ground traffic signal light group qxi Entrance boot section of the interval equal to the entrance lane xi of the initial time of optical signal empties duration.Wherein, the entrance car Road xi entrance boot section empties duration and is expressed as TYD_qk_xi,Wherein, V'YD_qk_xiCan Equal to Vlk_maxOr Vlk_minOr Vlk_q, wherein, the Vlk_maxRepresent the Maximum speed limit of the grade crossing, Vlk_minTable Show the minimum speed limit of the grade crossing, Vlk_qRepresent the desired speed of the grade crossing.Wherein, entrance is guided Area empties duration TYD_qk_xiIt is, for example, less than overlapping duration Tcd_xi。Vlk_minLess than Vlk_max。Vlk_qValue space be greater than or wait In the Vlk_minAnd less than or equal to Vlk_maxAny real number, i.e. Vlk_qMore than or equal to the Vlk_minAnd be less than or equal to Vlk_max。
Concrete example, for powered Nxi horizontal ground traffic signal light group by from horizontal ground traffic signals Lamp group qxi starts to send forbidden optical signal successively and shows the situation that at the uniform velocity guides speed, then, Nxi horizontal ground friendship Horizontal ground traffic signal light group i in ventilating signal lamp group sends the initial time of forbidden optical signal, is handed over relative to horizontal ground The interval duration that ventilating signal lamp group qxi sends the initial time of forbidden optical signal is expressed as TΔr_i_qxi, wherein,Li_qxiRepresent the horizontal ground traffic signal light group i relative to institute Horizontal ground traffic signal light group qxi spacing is stated, the horizontal ground traffic signal light group i is described Nxi horizontal 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 away from the entrance lane xi and empty when phase duration adds excessive phase duration, Described 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, which terminates also to remain, to be emptied when phase duration adds excessive phase duration, drives the Nxi transverse direction ground traffic signal light Group sends alert traveling optical signal successively since the horizontal ground traffic signal light group qxi, wherein, described Nxi horizontal ground Horizontal ground traffic signal light group hair nearer transverse direction ground traffic signal light group qxi described in distance among traffic signal light group The initial time of responding traveling optical signal is more early, when the horizontal ground traffic signal light group pxi sends the starting of alert traveling optical signal Carve, any one the other horizontal ground traffic signal light group being later than in described Nxi horizontal ground traffic signal light group are sent 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 Entrance boot section of the interval equal to the entrance lane xi that group qxi sends the initial time of alert traveling optical signal empties duration.
In actual applications, the executive agent of the above method can be the driving control of the signal lamps such as semaphore, array driver Control equipment.The semaphore referred in the embodiment of the present application may also be 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 transverse direction 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 for the array driver being connected with semaphore.
For example, start/stop time (such as start/stop time for phase of passing through, the excessive phase of the control phase due to entrance lane The start/stop time of position or the start/stop time of forbidden phase etc.) determined by semaphore, the start/stop time of these phases can record In the multiphase traffic time allocation table that semaphore is safeguarded, therefore, when semaphore can learn the start-stop of control phase 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 away from the entrance lane xi Prominent control phase terminates also to remain overlapping duration Tcd_xiWhen.And array driver then can from semaphore or (or with semaphore connect The other equipment for connecing or being controlled by semaphore) direct or indirect learn that what moment is the control away from the entrance lane xi The upper crossing conflict control power phase of phase terminates also to remain overlapping duration Tcd_xiWhen.For example, array driver can Based on from semaphore (or the other equipment for being connected or being controlled by semaphore with semaphore) for current phase or forbidden phase The countdown signal of position, it is a upper crossing conflict control for the control phase away from the entrance lane xi to learn what moment Power phase terminates also to remain overlapping duration Tcd_xiWhen.
Therefore, in some technical schemes of the embodiment of the present application, by introducing entrance boot section and crossing conflict control The overlapping mechanism of system power phase, when terminating also to remain overlapping duration away from current control phase, just can control current control phase Next crossing conflict control power phase of position starts to let pass.It is next at the end of being so achieved that current control phase also not Crossing conflict control power phase has begun to, and realizes the overlapping of crossing conflict control power phase, and then cause next crossing punching The vehicle of the corresponding entrance lane of control of dashing forward phase can in advance accelerate in entrance boot section, in this way, during its arrival crossing Speed may be of a relatively high, therefore can just 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 are sent The interval at the time of optical signal of vehicle pass-through is allowed to be equal to overlapping duration, in this way, the vehicle on entrance lane xi is in the Nxi The safety guiding of individual horizontal ground traffic signal light group is descending when sailing to crossing, before with entrance lane xi control phase A upper control phase for crossing conflict is over, thus advantageously allow the vehicle on entrance lane xi crossing not with The current vehicle of other crossing conflicts is collided with each other, and then the vehicle advantageously allowed on entrance lane xi runs over the peace at crossing Full property is ensured.
Illustrate below by an instantiation.Assuming that the plane cross intersected in the presence of a north-south and East and West direction intersects 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 (for example north-south is straight Runway, north-south left turn lane, the control phase of East and West direction Through Lane and East and West direction left turn lane) circulation one week. The set-up mode of the control phase in each group crossing conflict track in traditional scheme can be as shown in Fig. 5-b citings, each group crossing Conflict track control phase between there is no temporal overlapping, when whole plane cross intersection phase cycling it is total Duration assumes 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 in this 4 groups of crossings conflict track of changing trains or buses typically is respectively 30 seconds.Assuming that the control of north-south left turn lane Phase when a length of 30 seconds, during the non-controlling power phase of exemplified north-south left turn lane is 0~90 second, Fig. 5-b in Fig. 5-b The control phase of exemplified north-south left turn lane is 90~120 seconds.Wherein, the control phase of north-south left turn lane Including current phase (such as green light phase) 25 seconds, transition phase (such as amber light phase) 3 seconds, empty phase (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 subtracted herein of phase Driver's reaction time+vehicle launch time etc. is regarded as, current phase loss duration is can be described as)+available transition phase Shi Changyue 1 second is (assuming that transition phase duration includes for 3 seconds：Available transition phase duration about 1 second+not available transitional face It is about 2 seconds during position), amount to about 24 seconds.The total losses time of single control phase is (when can claim the transition loss of control phase It is long) it is about 2 seconds when being equal to not available transition phase duration about 2 seconds+emptying phase 2 seconds+current phase loss, that is to say, that The total losses time, which amounts to, to be reached about 6 seconds.
Implement after application scheme, it is assumed that the overlapping duration (i.e. preaceleration duration) of crossing conflict control power phase is 8 seconds. Spacing between stop line and crossing safety line is adapted with overlapping duration, and then can realize that crossing conflicts track (for example, north and south To Through Lane and East and West direction Through Lane) control phase between overlapping 8 seconds.The each group road set according to overlap mode The various phases in mouth conflict track can be as shown in Fig. 5-c and Fig. 5-d citings.
In illustrating 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 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 can extend to 38 seconds by original 30 seconds, and (Fig. 5-c pass the imperial examinations at the provincial level illustration The control phase for going out north-south left turn lane is the control phase of exemplified north-south left turn lane in 0~82 second, 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 Being about+emptying phase about 3 seconds (crossing empties about 2 seconds+entrance boot section and emptied about 1 second)+when crossing phase 2 seconds, pass through phase loss Shi Changyue 2 seconds, amounts to about 7 seconds), amount to about 31 seconds.North-south Through Lane, East and West direction Through Lane and East and West direction left turn lane Situation it is similar.
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, relative the lifting ((31- of effectively current duration of the single control phase of north-south left turn lane 24)/24) ≈ 29%, the increase of effectively current duration inevitably facilitates raising vehicle pass-through efficiency.
In being illustrated shown in Fig. 5-d, with north-south Through Lane, north-south left turn lane, East and West direction Through Lane and east The turn left duration of control phase in this 4 groups of crossings conflict track of track of west was fixed to exemplified by 30 seconds, in such case Under, the overlapping of phase is weighed by crossing conflict control, as shown in Fig. 5-d citings, the lane of whole plane cross intersection Phase total duration was 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 In the case that degree shortens (being shorten to 96 seconds by 120 seconds), because north-south Through Lane, north-south left turn lane, East and West direction are straight The duration of the control phase in this 4 groups of crossings conflict track of runway and East and West direction left turn lane does not all shorten, therefore accordingly The effectively current duration of control phase does not shorten.Because the total duration of the phase cycling of whole plane cross intersection shortens , then the lane for 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 will necessarily also 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, total duration can be used relatively more in plane cross intersection phase cycling 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 of reduction control phase accounts for the proportion of control phase duration, and the means generally used are by plane ten The total duration of the phase cycling of word intersection sets 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 make it that the time of the red lights such as pedestrian and vehicle is all very long, it is this wait red light when with When challenged people's tolerance limit, cause extensively to be denounced by people.
The overlapping duration of phase is weighed (i.e. in advance with time upper adjacent crossing conflict control in being illustrated shown in Fig. 5-c and Fig. 5-d Accelerate duration) to illustrate exemplified by 8 seconds, overlapping duration is 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 other durations less than corresponding control phase duration, corresponding embodiment can be by that analogy. Illustrate in being illustrated shown in Fig. 5-c and Fig. 5-d so that control phase includes current phase, transition phase and empties phase as an example, Certainly, control phase is also likely to be other composition forms illustrated in Fig. 2-c, and such as control phase may include current phase Position and empty phase, but do not include transition phase.Control phase can be with such for the corresponding embodiment of other composition forms 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 effectively current duration of relative lifting on the premise of immobilizing, or can also be constant in single control phase duration On the premise of shorten the phase cycling total duration of whole plane cross intersection.Phase is weighed by introducing crossing conflict control Overlapping mechanism and entrance boot section, not only contribute to offset the transition loss duration of control phase, 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 passes through Vehicle is also more, and traffic efficiency is also higher.The technical scheme of the embodiment of the present application with by take extension phase cycling it is total Duration is compared to reduce some traditional schemes of the transition loss duration proportion of control phase, not only can significantly reduce whole flat The phase cycling total duration of face right-angled intersection, and the red light stand-by period is shortened relatively, advantageously reduce fuel oil and disappear Consumption and discharge amount of exhaust gas.
As an example it is assumed that daily will be by 5 plane cross intersections by each car, it is assumed that each plane cross is handed over Cross road mouth waits 30 seconds red lights less, and averagely 1 liter of gasoline is calculated fuel consumption per hour during idling, then with 1,000,000, certain city Car is calculated, and the fuel oil of more than one hundred million members can be saved every year.For example, (* 1 liter/60 minutes 5*0.5 minutes) * 360 days * 100 ten thousand= 15000000 liters.Assuming that every liter of oil is by 7 yuan of calculating, 15,000,000 liters of * 7 yuan=105,000,000 yuan of oil can be saved every year.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, the facility such as original sensing of taking pictures can be continuing with substantially.Mainly adjustment each group crossing conflict control weighs phase Start/stop time, the safe line position in crossing will be arranged in the prior art, and (such as transverse direction 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 transverse direction ground traffic signal light group qxi's Set location) separated 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 again from people's row horizontal stroke during vehicle start Road, which is popped out, to be come, and need not also worry that having the vehicle made a dash across the red light to knock comes when pedestrian goes across the road again 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 is also longer.When the distance between two grade crossings When closer, easily cause vehicle to be detained in crossing, can thus influence corresponding next control phase to be let pass Vehicle is by crossing, so as to cause congestion to occur, is commonly called as rushing green light.It is former that the big traffic congestion of traffic of misty rain day is also due to this mostly Caused by.After some technical schemes for implementing 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.
