Wherein, the Parking Entrance of grade crossing can also be referred to as entrance driveway.One Parking Entrance of grade crossing may include one or many Bar entrance lane, entrance lane is alternatively referred to as import track.The exit ramp of grade crossing can also be referred to as downstream road.Grade crossing An exit ramp may include one or more exit lane, exit lane is alternatively referred to as downstream track.It is main in the relevant drawings of the embodiment of the present application If by Parking Entrance be located at corresponding exit ramp right side as a example by, and some national Parking Entrances be 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 possible identical, part of the guiding of this plurality of entrance lane is identical or mutual Differ.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 includes 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 entrance lanes can be referred to as the left-hand rotation entrance of Parking Entrance X Track, left-hand rotation entrance lane can abbreviation left turn lane.That assumes other 3 entrance lanes in above-mentioned 6 entrance lanes is directed to straight trip, then This 3 entrance lanes can be referred to as the straight trip entrance lane of Parking Entrance X, and straight trip entrance lane can abbreviation Through Lane.Assume above-mentioned 6 entrance cars 1 entrance lane of residue in road be directed to turn right, then this 1 entrance lane can be referred to as the right-hand rotation entrance lane of Parking Entrance X, turn right into Mouthful track can abbreviation right-turn lane, by that analogy.
For example, cruciform plan intersection (such as shown in Fig. 1-a~Fig. 1-b citings) typically may include 4 Parking Entrances and 4 go out Mouth road, every Parking Entrance may include one or more entrance lane, and every exit ramp may include one or more exit lane.T-shaped plane is handed over Cross road mouth generally comprises 3 Parking Entrances and 3 exit ramps, and every Parking Entrance may include one or more entrance lane, and every exit ramp may include one Bar or a plurality of exit lane.Certainly the Parking Entrance of some grade crossings and the quantity of exit ramp are likely to unequal, such as certain cruciform plan Intersection is likely to only include 3 Parking Entrances and 4 exit ramps.
In some cases, the guiding of some entrance lanes possibly transformable (i.e. revocable), such as in some period entrance cars Road is left turn lane, and it may be Through Lane in other periods, and this track can referred to as be oriented to changeable driveway, other analogues By that analogy.
In some cases, the guiding of some entrance lanes is probably multiple, and for example certain entrance lane both can be Through Lane, while it is yet It can be right-turn lane.The concrete such as rightmost entrance lane of certain Parking Entrance may both be Through Lane, while be also right-turn lane, and this car Road can be referred to as multi-guide track or compound direction track, and other analogues can be by that analogy.
The travel direction in track is usually fixed, but in some cases, and the travel direction in some tracks is also likely to be variable (i.e. non-solid Fixed), such as tide track is exactly a kind of variable track of typical travel direction, and the transformable track of travel direction is also referred to as traveling side To changeable driveway.The travel direction in track for example can for east orientation (i.e. eastbound), west to (heading 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 the left turn lane in the Parking Entrance is also referred to as east orientation left turn lane, some East orientation left turn lane is also referred to as eastbound left turn lane under scene, and the Through Lane in the Parking Entrance is also referred to as east orientation Through Lane, is having Under scene, east orientation Through Lane is also referred to as eastbound Through Lane, and 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 refers to adjacent with crossing Or the lane line for crossing, or refer to lane line that is adjacent with crossing or crossing.Wherein, the stop line of entrance lane can set Put the safe line position in crossing in the entrance lane.Or relative to the travel direction of entrance lane, 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, the stop line of entrance lane is typically all the crossing peace for being arranged on the entrance lane Full line position, 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 entrance The travel direction in track, the stop line of the entrance lane be arranged on after the crossing safety line of the entrance lane as a example by inquiring into, that is to say, that this Shen Please embodiment 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, and the stop line of entrance lane is moved relative to after the crossing safety line of the entrance lane, and then Define brand-new stop line layout type.Wherein, the set location of the stop line of entrance lane can be relatively-stationary, i.e. entrance lane Crossing safety line and the stop line of the entrance lane between spacing can be relatively fixed, it is of course also possible to be based on environmental factorss and scene need Factor carries out the adjustment of adaptability to the set location of the stop line of entrance lane.
Vehicle on each track of grade crossing can be allowed to pass through under the control of traffic light (allow it is current can be referred to as Fair row) or no through traffic (no through traffic can be referred to as forbidden) or warning current (warning is current to be may be simply referred to as warning row), in general, certain enters The corresponding traffic light in mouth track can control the vehicle on the entrance lane and allow or alert row or forbidden.Wherein, the car on the entrance lane is controlled The phase place let pass can be referred to as the current phase place (current phase place be alternatively referred to as clearance phase place or fair line phase) of the entrance lane, conventional art In because corresponding traffic light send the color of optical signal during current phase place be green, therefore, in the conventional technology, phase place one of passing through As also referred to as green light phase place, in the technical scheme of the embodiment of the present application, corresponding traffic light send the face of optical signal during current phase place Color is not limited to green, 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 a kind of optional embodiment in green simply the embodiment of the present application that period corresponding traffic light send the color of optical signal.Control The phase place of the Pedestrian Zone At any time on entrance lane can then be referred to as the forbidden phase place of the entrance lane, in the conventional technology, due to corresponding traffic light The color of sent optical signal is red during forbidden phase place, therefore forbidden phase place is typically also referred to as red light phase place, this Shen in conventional art Please corresponding traffic light send optical signal during forbidden phase place in embodiment color be not limited to redness, and can be expanded to use Corresponding traffic light send the face of optical signal during any solid color or the combination of several colors that indicate that no thoroughfare for vehicles, forbidden phase place Color is a kind of optional embodiment in red simply the embodiment of the present application.Similar, the phase place for controlling the vehicle police's row on entrance lane can The referred to as alert line phase (alert line phase can also claim transition phase place) of the entrance lane, because corresponding traffic light send light in conventional art Police's line phase is typically also referred to as amber light phase place, the embodiment of the present application during the color of signal is yellow, therefore conventional art during alert line phase In corresponding traffic light send optical signal during alert line phase color be not limited to yellow, and can be expanded to can be used to indicate that police The color that corresponding traffic light send optical signal during showing any solid color or color combination of vehicle pass-through, alert line phase is yellow It is a kind of optional embodiment in the embodiment of the present application.
Illustrate, " phase place " mentioned in certain some traffic specification typically acquiescence be for phase place (such as green light phase place) of passing through, i.e., certain That current phase place (such as green light phase place) is referred to as into phase place in some traffic specifications, even do not pay special attention in these traffic specifications forbidden phase place and Transition phase place these concepts.The management comparatively become more meticulous to the enforcement of each track, therefore especially area are directed primarily in the scheme of the embodiment of the present application Divide current phase place, forbidden phase place and transition phase place these three different phase place concepts.
In general, continuous current phase place, transition phase place and the forbidden phase place of certain entrance lane can form the single phase place of the entrance lane Cycle, the total duration of two neighboring phase cycling can fix (the two neighboring phase cycling of the entrance lane 01 as shown in illustrating in Fig. 2-a it is total when Length is 60 seconds) or unfixed (total duration of the two neighboring phase cycling of the entrance lane 02 as shown in Fig. 2-a citings).Same entrance The phase cycling of two entrance lanes of the identical guiding in road arrange may it is identical (two left turn lanes of the Parking Entrance Y as shown in Fig. 2-b citings Phase cycling is identical) or it is different.The phase cycling of different two entrance lanes being oriented to of same Parking Entrance is arranged may be identical or different.Have one Under a little scenes, transition phase place can even is that in this case, phase cycling does not only include current phase place and forbidden phase place, and does not include Transition phase place.
" crossing conflict track " this conception of species is set forth below, crossing conflict track is relative concept, when the crossing punching each other of certain two entrance lane Prominent track, represents that driving trace of the wagon flow on this two entrance lanes through crossing is present and intersects (or claiming the presence of intertexture), i.e. crossing punching each other There is intersection in driving trace of the wagon flow on any two entrance lanes in prominent track through crossing.Such as East and West direction Through Lane and north-south straight traffic There is intersection in the road track of crossing conflict each other, driving trace of the wagon flow on East and West direction Through Lane and north-south Through Lane through crossing, for example Shown in Fig. 1-c citings, if the wagon flow headed west on Through Lane and southern row Through Lane is while through crossing, then, this two bursts of wagon flows will at crossing Clash.Fig. 1-c are also exemplified to head west the Through Lane and northern row Through Lane also track of crossing conflict each other, other cars of crossing conflict each other The situation in road 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.In simple terms, crossing each other The current phase place of current phase place crossing conflict each other of two entrance lanes in conflict track.Similar, two entrance cars in the track of crossing conflict each other The transition phase place in the road transition phase place of crossing conflict each other.In the embodiment of the present application, conflict current phase place in crossing 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 entrance car Wagon flow on road crosses crossing, can represent that the wagon flow on the entrance lane obtains the right for crossing crossing.Wherein, in transition phase place (if present) Or these vehicles of the stop line of certain entrance lane are just crossed in the end of current phase place, generally need the regular hour to cross crossing, in order to avoid These vehicles sail the vehicle at crossing in crossing conflict with from another crossing track that conflicts, therefore, proposing in some traffic specifications generally need to be to 2 The time of or so second safe can be sailed with these vehicles for guaranteeing the stop line just crossed in the end of transition phase place (if present) or current phase place Crossing is crossed, this section is used for into time for emptying in some traffic specifications and is referred to as to empty phase place and (wherein, is emptied phase place similar in some traffic rule Alleged crossing full red signal interval in model).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 place.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, 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 part or all of of the forbidden phase place of the entrance lane.When exist transition phase place and In the case of emptying phase place, control phase place may include current phase place, transition phase place and empty phase place.Do not exist and empty when there is transition phase place In the case of phase place, control phase place includes current phase place and transition phase place.When do not exist transition phase place but presence empty phase place in the case of, control System power phase place includes current phase place and empties 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) include current phase place, transition phase place and Empty phase place；Or the control phase place of certain entrance lane (such as entrance lane x07) may include current phase place and empty phase place；Or certain enter The control phase place of mouth track (such as entrance lane x06) includes current phase place and transition phase place；Or certain entrance lane (such as entrance lane X08 control phase place) can be equal to current phase place.The phase place mentioned in some traffic specifications is likely to be defaulted as control phase place, i.e., these It is probably that control phase place is referred to as into phase place in traffic specification.
The concept of " crossing conflict control weigh phase place " is set forth below, conflict control power phase place in crossing is relative concept, in simple terms, road each other Each other crossing conflict control weighs phase place to the control phase place of two entrance lanes in mouth conflict track.Conflict control power phase place in crossing can referred to as conflict control System 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 be directed to track certain A little concepts (such as some " phase place " concepts) are equally applicable in the scene for crossing.From the point of view of broadly, crossing and track Walkway can all be regarded as, walkway is that, for the current road of object that passes through, walkway includes crossing and track (such as grade crossing Entrance lane, exit lane etc.) etc..Wherein, the object for passing through on walkway referred to as current object (current object be probably pedestrian or Vehicle etc.), by the referred to as current object data stream (referred to as current stream) of the object data stream passed through on walkway.The object passed through on crossing can Including pedestrian etc., the object data stream passed through on crossing is including pedestrian stream etc..The object passed through for example on track may include vehicle etc., in car The object data stream passed through on road is including wagon flow etc..
For the scene of crossing, also there may be the concepts such as current phase place, transition phase place and the forbidden phase place of crossing, also there may be people The concept such as the control phase place of row lateral road and non-controlling power phase place.It is likely to conflict each other between crossing and some tracks, because people's row is horizontal The driving trace of the wagon flow on artificial abortion and certain track on road there may be intersection.Broadly see, when two walkways (the two walkways may All be track, or it is track to be likely to one of them, and another is crossing) the travel track of current stream exist and intersect, then this Two walkways can mutually be referred to as conflict road, and the current stream conflicted each other on two walkways in road passes through within the identical period, then two lead to Current stream on trade may be clashed just.If the conflict road of certain walkway (such as track or crossing) is track, this conflict road Can be described as the track that conflicts；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 crossing can unite Referred to as conflict.
For ease of simplifying description, in application scheme description, no through traffic optical signal can referred to as forbidden optical signal or A1 class optical signals, it is allowed to Current optical signal can referred to as permit traveling optical signal or current optical signal or A2 class optical signals, and the current optical signal of warning can abbreviation or alert traveling optical signal or A3 Class optical signal.Specifically, forbidden optical signal is indicated for forbidding the current object of corresponding walkway (such as track or crossing) (such as Vehicles or pedestrians etc.) current optical signal, for example, the traffic light in certain track forbid the car in the track during sending forbidden optical signal Current, the vehicle pass-through of the traffic light of certain crossing forbidden crossing during sending forbidden optical signal.Fair traveling optical signal be for Indicate the optical signal for allowing the current object (such as vehicles or pedestrians) of corresponding walkway (such as track or crossing) current, for example certain The traffic light in track permit the traffic light 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 the logical of corresponding walkway (such as track or crossing) The current optical signal of row object (such as vehicle or pedestrian), the traffic light in such as certain track warn the track during sending alert traveling optical signal Vehicle pass-through, the traffic light of certain crossing warn the vehicle pass-through of the crossing during sending alert traveling optical signal.Other situations can be with 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 be according to concrete scene needs To set.
For example, forbidden optical signal can be red light signal, wherein, red light signal is specifically as follows the red light signal of flicker and/or non- The red light signal of flicker.Wherein, nonflickering red light signal may be simply referred to as normal red signal light, and the red light signal of flicker may be simply referred to as red sudden strain of a muscle Optical signal.Forbidden optical signal is indicated for that no through traffic the current optical signal of object (such as vehicles or pedestrians), therefore any one can use Forbidden optical signal is considered as in the optical signal for indicating to forbid the current object (such as vehicles or pedestrians) of corresponding walkway current, then forbidden The form of expression of optical signal is not limited to the example above, for example, also the optical signal of several colors can combine according to certain rule to indicate to prohibit Only the current object of corresponding walkway passes through, 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, green light signal and/or nonflickering green that green light signal concretely flashes Optical signal.Nonflickering green light signal can referred to as evergreen optical signal, the green light signal of flicker may be simply referred to as blue flash optical signal.Fair traveling optical signal The optical signal for allowing the current object (such as vehicles or pedestrians) of corresponding walkway current is indicated for, therefore, any one can be used in referring to The optical signal that showing allows the current object (such as vehicles or pedestrians) of corresponding walkway current is considered as permitting traveling optical signal, then permit row light letter Number the form of expression be not limited to the example above, for example also the optical signal of several colors can be combined according to certain rule logical to indicate to allow Row object passes through, then the optical signal of these forms of expression is also regarded as permitting traveling optical signal.
Again for example, alert traveling optical signal can be yellow optical signal, yellow optical signal and/or nonflickering yellow that yellow optical signal concretely flashes Optical signal.Nonflickering yellow optical signal can abbreviation Chang Huangguang signals, the yellow optical signal of flicker may be simply referred to as yellow flash signal.Alert traveling optical signal The optical signal for warning the current object (such as vehicles or pedestrians) of corresponding walkway current is indicated for, therefore, any one can be used in referring to The current optical signal of current object (such as vehicles or pedestrians) of corresponding walkway of warning is considered as warning traveling optical signal, then alert row light letter Number the form of expression be not limited to the example above, for example can also by the optical signal of several colors according to certain rule combine for indicate police Show that current object passes through, 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 have one or more performance Form, alert traveling optical signal there may be one or more form of expression.But due to permitting traveling optical signal, forbidden optical signal and alert traveling optical signal indicative function It is different, then to permit the form of expression of traveling optical signal, forbidden optical signal and alert traveling optical signal also different, in other words, the table of forbidden optical signal Do not occur simultaneously between existing form set, the form of expression set of alert traveling optical signal and the form of expression set of forbidden optical signal.
Wherein, alert traveling optical signal is indicated for warning the optical signal of the current object (such as vehicles or pedestrians) of corresponding walkway, therefore From in certain angle, alert traveling optical signal is considered as a kind of transition signal (therefore alert traveling optical signal is alternatively referred to as excessive optical signal), indicates logical Row object fair row and it is forbidden between transition.If in some cases without the need for such transition, then be likely to just without the need for this mistake of alert traveling optical signal Cross signal.
For ease of simplifying describing mode, in some scheme descriptions of the application, A1 classes optical signal can be sent but A2 class optical signals can not be sent Can be described as " A1 class signal lighties " with the signal lighties of A3 class optical signals.A2 classes optical signal can be sent but A1 classes optical signal and A3 can not be sent The signal lighties of class optical signal are properly termed as " A2 class signal lighties ".A3 classes optical signal can be sent but A1 classes optical signal and A2 class light can not be sent The signal lighties of signal are properly termed as " A3 class signal lighties ".A1 classes optical signal and A2 classes optical signal can be sent but A3 class optical signals can not be sent Signal lighties can be described as " A12 class signal lighties ".A1 classes optical signal and A3 classes optical signal can be sent but the letter of A2 class optical signals can not be sent Signal lamp can be described as " A13 class signal lighties ".A2 classes optical signal and A3 classes optical signal can be sent but the signal lighties of A1 class optical signals can not be sent It is properly termed as " A23 class signal lighties ".Particularly, A1 classes optical signal can be sent and the letter of A2 classes optical signal and A3 class optical signals can be sent Signal lamp can be described as " AA class signal lighties ", 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, crossing traffic letter can be set on the part or all of entrance lane of grade crossing Signal lamp array.Wherein, the mode that crossroad traffic signal lamp array is arranged on part or all of entrance lane may be same or like.Satisfy the need below Oral sex ventilating signal lamp array carries out citing introduction in greater detail.
The embodiment of the present application provides a kind of crossroad traffic signal lamp array, wherein, the crossroad traffic signal lamp array can include Nxi laterally Ground traffic signal light group.Wherein, road of the Nxi horizontal ground traffic signal light group including the entrance lane xi for being arranged at grade crossing The horizontal ground traffic signal light group pxi of the safe line position of mouth.The Nxi horizontal ground traffic signal light group also includes being arranged at the entrance car The horizontal ground traffic signal light group qxi of the parking line position of road xi.
Wherein, the roadway segment delimited between the crossing safety line and stop line of entrance lane forms entrance boot section, and entrance boot section is also regarded as Entrance boot section.For example, the roadway segment delimited between the crossing safety line of entrance lane xi and the stop line of entrance lane xi forms entrance lane xi Entrance boot section (the entrance boot section of entrance lane xi).
Wherein, the signal lighties quantity that any two ground traffic signal light group in the Nxi horizontal ground traffic signal light group includes can be identical Or it is different.Wherein, the Nxi is the integer more than 1.Each horizontal ground traffic signal in the Nxi horizontal ground traffic signal light group Lamp group includes at least one signal lighties (such as 1 or at least 2 signal lighties).
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 with wireless type driving signal input mouth And/or wired driving signal input mouth.The horizontal ground traffic signal light group i is its in the Nxi horizontal ground traffic signal light group In a horizontal ground traffic signal light group or any one horizontal ground traffic signal light group.
Wherein, the spacing between any two adjacent transverse ground traffic signal light group in the Nxi horizontal ground traffic signal light group is equal Or part is equal or is not mutually equal.For example, any two adjacent transverse ground traffic signal light group in Nxi horizontal ground traffic signal light group Between spacing can be 1 meter, 1.5 meters, 2 meters, 2.5 meters, 3 meters or other values.Again for example, the Nxi horizontal ground traffic signal light In group, spacing between two more remote adjacent transverse ground traffic signal light groups of the horizontal ground traffic signal light group pxi is less (to exist In the travel direction of entrance lane xi, between two adjacent transverse ground traffic signal light groups in the Nxi horizontal ground traffic signal light group Spacing gradually increases), or in the Nxi horizontal ground traffic signal light group, it is more remote apart from the horizontal ground traffic signal light group pxi 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 laterally ground hand over The spacing between two adjacent transverse ground traffic signal light groups in ventilating signal lamp group is gradually reduced).Certainly, the Nxi laterally ground friendship Spacing between two adjacent transverse ground traffic signal light groups of ventilating signal lamp group is also likely to be random change or other Changing Patterns, and is differed Surely the Changing Pattern for being gradually reduced along certain direction or gradually increasing of the example above is presented.
For example, the two neighboring horizontal ground traffic signal not being only arranged in the Nxi of entrance boot section horizontal ground traffic signal light group Spacing can be equal between lamp group, and the two neighboring horizontal ground traffic signal light group in the Nxi horizontal ground traffic signal light group sends The interval of the initial time of fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) also can be equal, and this pattern can claim " when equidistantly waiting Pattern ".Again under such as some scenes, the two neighboring horizontal ground being arranged in the Nxi of entrance boot section horizontal ground traffic signal light group Spacing between traffic signal light group can be equal, but the two neighboring horizontal traffic above-ground letter in the Nxi horizontal ground traffic signal light group Signal lamp group sends the interval of the initial time of fair traveling optical signal (or forbidden optical signal or alert traveling optical signal), and this pattern can claim " equidistantly Not isochronous mode ".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 Nxi laterally in the traffic signal light group of ground it is two neighboring laterally The interval that face traffic signal light group sends the initial time of fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) is equal, and this pattern can claim " unequal-interval pattern when waiting ", 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 Lamp group can uniformly branch between the crossing safety line and stop line of entrance lane xi, such as every 1 meter in the entrance boot section of entrance lane xi One horizontal ground traffic signal light group is set, and the entrance boot section of entrance lane xi is divided into 10 and is entered by Nxi horizontal ground traffic signal light group Mouth roadway segment, the spacing between the horizontal ground traffic signal light group of arbitrary neighborhood two is 1 meter, the horizontal ground traffic signal of arbitrary neighborhood two Lamp group send the initial time of fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) interval can it is equal (such as 0.2 second, 1 second, 1.5 seconds or 2 seconds etc.) or.For example assume that Nxi is equal to 6 again, the entrance guiding section length of entrance lane xi is 10 meters, then Nxi laterally traffic above-ground Signal lighties group can uniformly branch it is between the crossing safety line and stop line of entrance lane xi, such as every 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 the entrance boot section decile of entrance lane xi For 5 entrance lane sections, the spacing between the horizontal ground traffic signal light group of arbitrary neighborhood two is that the horizontal traffic above-ground of 2 meters of arbitrary neighborhoods two is believed Signal lamp group sends the interval of the initial time of fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) can be equal or different.Wherein, the Nxi Other equal set-up modes of spacing can be with this between two neighboring horizontal ground traffic signal light group in individual horizontal ground traffic signal light group Analogize.
Wherein, when the horizontal ground traffic signal light group i includes at least two signal lighties, then among the horizontal ground traffic signal light group i The shared identical drive signal of at least two signal lighties, or any two signal lighties among the horizontal ground traffic signal light group i use it is different Drive signal.
It is understood that as a rule, the working condition of several signal lighties of shared identical drive signals is synchronous change, for example, share Several signal lighties of identical drive signal will simultaneously be lighted or will be closed simultaneously, because these signal lighties are come in the lump by identical drive signals Drive control.The use of the working condition of different two signal lighties of drive signal may not be synchronous change, certainly it could also be possible that synchronous become Change.In general, using from same drive signal output port, (drive signal output port can refer to array driver or traffic signaling equipment etc. Drive signal output port) working condition of the signal lighties of drive signal that exported is synchronous change, if actual conditions is that drive signal is defeated The drive signal that exit port is exported sequential etc. during from drive signal output port arriving signal lamp is not changed.In general, use The working condition of the signal lighties of the drive signal exported from different driving signal output port may not be synchronous change, be also possible to certainly It is synchronous change.
Wherein, entrance lane xi can be grade crossing wherein one entrance lane, or entrance lane xi with can be intersection it is any One entrance lane.That is, the part or all of entrance lane of grade crossing can be according to the portion equivalent or similar to entrance lane xi Management side formula is disposing horizontal ground traffic signal light group etc..
It is appreciated that because the signal lighties in horizontal ground traffic signal light group are arranged at ground, therefore these signal lighties are also referred to as Face traffic light (can also referred to as " ground signal lamp ").If without special explanation, the horizontal ground referred among the embodiment of the present application is handed over Signal lighties in ventilating signal lamp group are ground traffic signal light.It is appreciated that because ground traffic signal light is arranged at ground, therefore setting Put in mode and product form, ground traffic signal light is different from high altitude traffic signal lighties, high altitude traffic signal lighties for example may include column Traffic light or cantilevered traffic light etc..
It is appreciated that laterally " horizontal " in the traffic signal light group of ground is intended to mean that the length direction and phase of horizontal ground traffic signal light group The travel direction for answering track is perpendicular or generally perpendicular, the length direction of at least horizontal ground traffic signal light group and the travel direction in corresponding track Between be it is uneven, the angular range between the length direction of horizontal ground traffic signal light group and the travel direction in corresponding track can be more than or wait In 45 ° and less than or equal to 90 °, above-mentioned angle for example can be equal to 90 °, 89 °, 85 °, 80 °, 78 °, 75 °, 60 °, 53 ° or 40 ° of person.Certainly, the angular range between the length direction of horizontal ground traffic signal light group and the travel direction in corresponding track is not limited to above-mentioned Citing scope.
Optionally, in some possible embodiments of the application, when the Nxi is the integer more than 2, the Nxi horizontal traffic above-ground is believed Signal lamp group also includes Nxi-2 horizontal traffic above-ground letter being arranged between the crossing safety line and the stop line on the entrance lane xi Signal lamp group.It is understood that the individual horizontal traffic above-ground letter of the Nxi-2 (such as Nxi=6, then Nxi-2=6-2=4, by that analogy) Signal lamp group potentially includes some or all of horizontal traffic above-ground between the crossing safety line and the stop line being arranged on the entrance lane xi Signal lighties group.
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；Described Nxi horizontal Earthward traffic signal light group includes：It is arranged on the horizontal ground traffic signal light of the safe line position in crossing of the entrance lane xi of grade crossing Group pxi, be arranged on entrance lane xi parking line position horizontal ground traffic signal light group qxi.Crossing safety line due to entrance lane xi with stop The roadway segment delimited between fare can form entrance boot section, and this just provides certain space basis for vehicle by the advance acceleration at crossing, and is Control vehicle sails the transport condition of the speed (i.e. vehicle rolls the speed of entrance boot section away from) and vehicle at crossing in entrance boot section into and provides necessarily Basis, and then cause the vehicle pass-through efficiency for improving grade crossing to become had certain space basis.Such as Nxi horizontal traffic above-ground letter Entrance boot section can be divided into several roadway segments by signal lamp group, using the Nxi optical signal that laterally ground traffic signal light group is sent so that More precise control is carried out to the speed that transport condition and vehicle of the vehicle in entrance boot section rolls entrance boot section away from becomes had possible, therefore this Sample is conducive to the safely controllable property of the vehicle pass-through for improving grade crossing.Also, the traffic signal light group of ground type be more convenient for driver identification Go out corresponding traffic control signal, and then be conducive to further improving the vehicle pass-through safely controllable property of grade crossing.
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 arranging horizontal ground traffic signal light group Road conditions before.The Parking Entrance (Parking Entrance X) of the left-hand component citing of Fig. 3 and the Parking Entrance (Parking Entrance Y) of right-hand component citing are respectively Including 3 entrance lanes.Parking Entrance includes the situation of the entrance lane of other quantity by that analogy.Parking Entrance Y shown in the citing of Fig. 3 right-hand components Front also has crossing, and the Parking Entrance X fronts shown in the left-hand component citing of Fig. 3 do not have crossing.
Referring to Fig. 4-a~Fig. 4-c, Fig. 4-a~Fig. 4-c are exemplified to arrange horizontal traffic above-ground on the front entrance lane with crossing Several possible road conditions after signal lighties group.The relevant position arranged on each entrance lane of the Parking Entrance in scene shown in Fig. 4-a citings Laterally ground traffic signal light group is generally within same straight line.In scene shown in Fig. 4-b citings, set on the partial inlet track of same Parking Entrance The horizontal ground traffic signal light group of the relevant position put generally within same straight line, the horizontal stroke of the relevant position arranged on another part entrance lane Earthward traffic signal light group is generally within same straight line, or even the stop line and other entrance cars that have some entrance lanes of same Parking Entrance The stop line in road may not be on the same line.
Wherein, in the left-hand component example and Fig. 4-b of Fig. 4-a for every entrance lane, main (the i.e. every entrance lane so that Nxi is equal to 4 as an example At least 4 horizontal ground traffic signal light groups of upper setting).Wherein, for every in the right-hand component example of Fig. 4-a and the right-hand component example of Fig. 4-c Bar entrance lane, is mainly 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 be equal or different.It is different The quantity of the horizontal ground traffic signal light group arranged on the entrance lane of Parking Entrance can be equal or different.
In the application some possible embodiments, the signal lighties ia among the horizontal ground traffic signal light group i can be in the first drive signal Driving under send forbidden optical signal, and the signal lighties ia can also send fair traveling optical signal, the signal under the driving of the second drive signal Lamp ia for example can be A12 class signal lighties.Or the signal lighties ia among the horizontal ground traffic signal light group i can be in the drive of the first drive signal Forbidden optical signal is sent under dynamic, and the signal lighties ia can also send fair traveling optical signal, and the signal lighties under the driving of the second drive signal Ia can also issue responding traveling optical signal in the driving of the 3rd drive signal, and the signal lighties ia for example can be AA class signal lighties.Wherein, the letter Signal lamp ia can be the one of signal lighties or any one signal lights among the horizontal ground traffic signal light group i.That is, in the application In some possible embodiments, individual signals lamp can send different optical signals under the driving of different driving signal.Specifically for example, traffic above-ground Part or all of signal lighties among signal lighties group i can send red light signal, and ground traffic signal light group under the driving of the first drive signal Part or all of signal lighties among i can second drive signal driving under send green light signal, and ground traffic signal light group i among portion Divide or whole signal lighties can send sodium yellow signal under the driving of the 3rd drive signal.
Optionally, in some possible embodiments of the application, i1 signal lighties among the horizontal ground traffic signal light group i are energy I2 signal lighties among the signal lighties of forbidden optical signal, and the horizontal ground traffic signal light group i are enough sent for fair traveling optical signal can be sent Signal lighties.It is or i1 signal lighties among the horizontal ground traffic signal light group i are the signal lighties that can send forbidden optical signal and described Laterally i2 signal lighties among the traffic signal light group i of ground can be the signal lighties that can send fair traveling optical signal, and the horizontal traffic above-ground is believed I3 signal lighties among signal lamp group i are the signal lighties that can send alert traveling optical signal.
Wherein, the i1, the i2 and the i3 are the integer more than 1.

Optionally, in the application some possible embodiments, horizontal ground described in the Nxi distance laterally in the traffic signal light group of ground Traffic signal light group qxi nearer horizontal ground traffic signal light group sends the starting of forbidden optical signal (or fair traveling optical signal or alert traveling optical signal) Moment is more early.The horizontal ground traffic signal light group pxi sends the initial time of forbidden optical signal, is later than the Nxi laterally traffic above-ground letter Other in signal lamp group any one horizontal ground traffic signal light groups sends the starting of forbidden optical signal (or fair traveling optical signal or alert traveling optical signal) Moment.As an example it is assumed that the Nxi horizontal ground traffic signal light group includes that horizontal ground traffic signal light group j1, horizontal traffic above-ground believe Signal lamp group j2 and horizontal ground traffic signal light group j3.The horizontal ground traffic signal light group j1, the horizontal ground traffic signal light group j2 and institute State horizontal ground traffic signal light group j3 be the position of the Nxi laterally among the traffic signal light group of ground it is adjacent 3 (such as wherein 3 or Any 3) horizontal ground traffic signal light group.Wherein, between the horizontal ground traffic signal light group j2 and the stop line of the entrance lane xi Spacing be more than, the spacing between the horizontal ground traffic signal light group j1 and the stop line of the entrance lane xi.Wherein, it is described laterally Spacing between the stop line of face traffic signal light group j2 and the entrance lane xi, less than the horizontal ground traffic signal light group j3 with it is described enter Spacing between the stop line of mouth track xi.
It is appreciated that the horizontal ground traffic signal light group j1 may be exactly horizontal ground traffic signal light group qxi, 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.Horizontal ground traffic signal light group J3 may be exactly horizontal ground traffic signal light group pxi, it is also possible to the crossing safety line and the parking being disposed on the entrance lane xi Horizontal ground traffic signal light group between line.
Optionally, in some possible embodiments of the application, the horizontal ground traffic signal light group j2 and the horizontal traffic above-ground Spacing between signal lighties group j1, fair row light is sent divided by the horizontal ground traffic signal light group j2 with the horizontal ground traffic signal light group j1 Business V obtained from the time difference of the initial time of signal (or forbidden optical signal or alert traveling optical signal)j1_j2, for example, it is smaller than or equal to the horizontal stroke The earthward spacing between traffic signal light group j2 and the horizontal ground traffic signal light group j3, divided by the horizontal ground traffic signal light group j2 With the time difference of the initial time that the horizontal ground traffic signal light group j3 sends fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) and The business V for obtainingj2_j3。
It is understood that working as above-mentioned Vj1_j2Equal to Vj2_j3, then horizontal ground traffic signal light group j1, the horizontal traffic above-ground letter can be represented Signal lamp group j2 and the horizontal ground traffic signal light group j3 are in by sending fair traveling optical signal (or forbidden optical signal or alert traveling optical signal) successively The guiding speed for revealing is at the uniform velocity.And work as above-mentioned Vj1_j2Less than above-mentioned Vj2_j3, then can represent horizontal ground traffic signal light group j1, it is described laterally Ground traffic signal light group j2 and the horizontal ground traffic signal light group j3 are by sending successively fair traveling optical signal (or forbidden optical signal or alert row light Signal) the guiding speed that presented is even acceleration or non-even acceleration.
It is appreciated that the powered Nxi horizontal ground traffic signal light group starts successively from the horizontal ground traffic signal light group qxi Fair traveling optical signal is sent, can be presented and at the uniform velocity be guided speed, can also present the speed change guiding speed of even acceleration or non-even acceleration, thus favorably Guide safely in the travel speed to vehicle in entrance boot section.
For example, when horizontal ground traffic signal light group qxi sends fair traveling optical signal, represent that the current vehicle allowed on entrance lane xi is crossed Laterally ground traffic signal light group qxi (allowing the vehicle on entrance lane xi to cross the stop line of entrance lane xi), (is for example stopped in vehicle Head car after horizontal ground traffic signal light group qxi) sail into after entrance boot section, except horizontal stroke in Nxi laterally ground traffic signal light group Under the guiding of the fair traveling optical signal that other horizontal ground traffic signal light groups earthward outside traffic signal light group pxi send successively, vehicle is progressively Cross these horizontal ground traffic signal light groups for sending fair traveling optical signal, send fair row light letter in horizontal ground traffic signal light group pxi afterwards Number guiding under, vehicle crosses horizontal ground traffic signal light group pxi (that is, crossing the crossing safety line of entrance lane xi), and vehicle is crossing horizontal stroke Earthward just enter crossing into crossing or after crossing is passed through after traffic signal light group pxi, finally cross crossing and enter respective downstream Track.Generally speaking, start to send fair row light successively from the horizontal ground traffic signal light group qxi in Nxi horizontal ground traffic signal light group Signal and present guiding speed (guiding speed be probably at the uniform velocity or it is non-at the uniform velocity) guiding under, vehicle will with less than or equal to this guiding speed The travel speed of degree crosses entrance boot section.It is appreciated that before horizontal ground traffic signal light group pxi sends fair traveling optical signal, if vehicle To travel in entrance boot section more than respective guide speed travel speed, then, vehicle is just likely to " making a dash across the red light " phenomenon occur, i.e., very may be used Vehicle can occurs, and (wherein, this horizontal ground traffic signal light group exists before certain horizontal ground traffic signal light group sends fair traveling optical signal Send and may be at OFF state before fair traveling optical signal or send 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 vehicle in entrance using Nxi horizontal ground traffic signal light group The travel speed of boot section is guided safely, and then is advantageously allowed vehicle and sailed crossing into safer speed, so not only improves lifting vehicle Crossing efficiency is crossed, is also beneficial to ensure the safety that vehicle crosses crossing.That is, the scheme of the embodiment of the present application, is conducive in vehicle The efficiency and safety aspect for crossing crossing accomplishes to take into account substantially.
The embodiment of the present application also provides the drive control method of crossroad traffic signal lamp array, and the crossroad traffic signal lamp array for example can be as above Any one crossroad traffic signal lamp array of embodiment offer is provided.Concrete such as crossroad traffic signal lamp array includes Nxi laterally traffic above-ground Signal lighties group；The Nxi horizontal ground traffic signal light group includes the safe line position in crossing of the entrance lane xi for being arranged at grade crossing Horizontal ground traffic signal light group pxi, the Nxi horizontal ground traffic signal light group also includes being arranged at the stop line position of the entrance lane xi The horizontal ground traffic signal light group qxi for putting.Each horizontal ground traffic signal light group in the Nxi horizontal ground traffic signal light group includes At least one (such as 1 or at least two) signal lighties.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 laterally traffic above-ground One of them horizontal ground traffic signal light group or any one horizontal ground traffic signal light group among signal lighties group.
Wherein, if the horizontal ground traffic signal light group i includes at least two signal lighties, then in the horizontal ground traffic signal light group i At least two signal lighties can share identical drive signal, or, any two signal lighties in the horizontal ground traffic signal light group i are not using Same drive signal.
Wherein, a kind of drive control method of crossroad traffic signal lamp array may include：When upper the one of the control phase place of the entrance lane xi Individual crossing conflict control power phase place terminates also to remain overlap duration Tcd_xiWhen, drive the Nxi laterally ground traffic signal light group from it is described laterally Face traffic signal light group qxi starts to send fair traveling optical signal successively.Described in distance among the Nxi horizontal ground traffic signal light group laterally The initial time that face traffic signal light group qxi nearer horizontal ground traffic signal light group sends fair traveling optical signal by driving is more early, the horizontal ground Traffic signal light group pxi is sent the initial time of fair traveling optical signal by driving, and other being later than in the Nxi horizontal ground traffic signal light group are appointed One horizontal ground traffic signal light group of meaning is sent the initial time of fair traveling optical signal by driving.For example can be by detection (directly or indirectly detection) The progress of the upper crossing conflict control power phase place of the control phase place of the entrance lane xi come learn be when entrance lane xi control The upper crossing conflict control power phase place of phase place terminates also to remain overlap duration Tcd_xiWhen.
It is to be appreciated that the possible equal or part of the corresponding overlap duration of the different entrance lane of the travel direction of approximately the same plane intersection is equal Or be not mutually equal.The corresponding duration that overlaps of the entrance lanes that travel direction is identical but guiding is different of approximately the same plane intersection may equal or portion Split-phase etc. is not mutually equal.The travel direction of approximately the same plane intersection and the corresponding duration that overlaps of the entrance lane of guiding all same may be equal Or part is equal or is not mutually equal.It is appreciated that overlapping duration Tcd_xiFor the corresponding overlap durations of entrance lane xi, entrance lane xi is that plane is handed over One of entrance lane or any one entrance lane of cross road mouth.
It is upper crossing conflict control power phase place knot that the horizontal ground traffic signal light group pxi sends the initial time of fair traveling optical signal The beam moment.That is, described horizontal ground traffic signal light group pxi and horizontal ground traffic signal light group qxi sends the initial time of fair traveling optical signal Interval TΔ_pxi_qxiEqual to overlap duration Tcd_xi.Overlap duration Tcd_xiThe preset value that can be storage (can be according to connecing from upper equipment or man-machine interaction The duration more new command that overlaps of mouth updates currently stored Tcd_xi) or overlap duration Tcd_xiCan be in real time calculated based on preset algorithm.For example overlap Duration Tcd_xi2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8.1 seconds, 10 seconds or other durations can be equal to.
As an example it is assumed that the entrance lane xi is eastbound Through Lane, then a upper crossing of the control phase place of the entrance lane xi Conflict control power phase place for example may be the southern row Through Lane of the grade crossing or northern row Through Lane or head west left turn lane or north The control phase place of row left turn lane, because, the eastbound Through Lane of grade crossing, the southern row Through Lane with the grade crossing Or northern row Through Lane or the track that conflicts each other between left turn lane or northern row left turn lane that heads west.Again it is assumed that the entrance lane xi is to head west Through Lane, then the upper crossing conflict control power phase place of the control phase place of the entrance lane xi for example may be the level-crossing road The control phase place of the southern row Through Lane of mouth or northern row Through Lane or eastbound left turn lane or southern row left turn lane, because grade crossing Head west 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 left turn lane Between conflict each other track, 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 Through Lane, East and West direction straight trip The control phase place in track is circulated.Wherein, the upper crossing conflict control power phase place of the control phase place of north-south left turn lane is thing Turn left the control phase place in track, the upper crossing conflict control power phase place of the control phase place of East and West direction left turn lane is north-south straight traffic The control phase place in road, the upper crossing conflict control power phase place of the control phase place of north-south Through Lane is the control of East and West direction Through Lane Power phase place.In scene shown in Fig. 5-a citings, it is assumed that the entrance lane xi is certain entrance lane in the left turn lane of north-south, then described The upper crossing conflict control power phase place of the control phase place of entrance lane xi is the control phase place of East and West direction left turn lane, is entered described in hypothesis again Mouth track xi is certain entrance lane in East and West direction left turn lane, then the upper crossing conflict control of the control phase place of the entrance lane xi System power phase place is the control phase place of north-south Through Lane, by that analogy.
In scene shown in Fig. 5-a citings, a length of T when north-south left turn lane is overlap with the control phase place of East and West direction left turn lanecd_3.Thing Turn left track it is overlap with the control phase place of north-south Through Lane when a length of Tcd_2.The control of north-south Through Lane and East and West direction Through Lane A length of T during the overlap of system power phase placecd_1.The overlap duration of the control phase place of East and West direction Through Lane and the control phase place of north-south left turn lane For Tcd_4.Wherein, Tcd_1、Tcd_2、Tcd_2And Tcd_4Can all equal 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 is just Vehicle provides certain space basis by the advance acceleration at crossing, and sails the speed at crossing into (i.e. vehicle rolls entrance boot section away to control vehicle Speed) and transport condition of the vehicle in entrance boot section provide certain basis, and then cause to improve the vehicle pass-through efficiency of grade crossing Become had certain space basis.Entrance boot section can be divided into several roadway segments by such as Nxi horizontal ground traffic signal light group, be utilized The Nxi optical signal that laterally ground traffic signal light group is sent so that entrance is rolled away to transport condition and vehicle of the vehicle in entrance boot section and is drawn Lead the speed in area carry out more precise control become to have had may, therefore, be so conducive to the safety of the vehicle pass-through for improving grade crossing can Control property.Also, 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 raising The vehicle pass-through safely controllable property of grade crossing.Specifically, by flexibly control Nxi laterally ground traffic signal light group in it is each laterally Ground traffic signal light group sends the initial time of fair traveling optical signal or alert traveling optical signal or forbidden optical signal, is advantageously implemented and passes through crossing to vehicle When time and speed relatively precise control, and then be conducive to further improving the vehicle pass-through safely controllable property of grade crossing.For example work as institute When the upper crossing conflict control power phase place for stating the control phase place of entrance lane xi terminates also to remain corresponding overlap duration, described Nxi is driven laterally Ground traffic signal light group starts to send fair traveling optical signal successively from the horizontal ground traffic signal light group qxi, wherein, Nxi laterally ground friendship The horizontal ground traffic signal light group qxi of distance among ventilating signal lamp group nearer horizontal ground traffic signal light group, sends the starting of fair traveling optical signal 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 come according to certain order Fair traveling optical signal is begun to send out successively, and this is just to carry out rationally suitable guiding by time of entrance boot section and speed to vehicle to establish Basis, for example, advantageously allow the guiding of the guiding speed that vehicle is presented in the Nxi optical signal that laterally ground traffic signal light group is sent Under, it is safely controllable efficiently to roll entrance boot section away from, and then be conducive to making vehicle cross crossing in safely controllable efficient mode.
It is understood that in actual applications, the powered Nxi horizontal ground traffic signal light group is believed from the horizontal traffic above-ground Signal lamp group qxi starts to send fair traveling optical signal successively, and can present at the uniform velocity guide speed or speed change guiding speed, and speed change guiding speed can be even adding (wherein, even acceleration guiding speed can be divided into the even acceleration guiding speed that initial velocity is zero to speed guiding speed and the even acceleration that initial velocity is not zero is drawn Lead speed) or non-even acceleration guiding speed.
Concrete example, for powered Nxi horizontal ground traffic signal light group from horizontal ground traffic signal light group qxi by starting successively Send fair traveling optical signal and present the situation of at the uniform velocity guiding speed, then, the horizontal traffic above-ground in Nxi horizontal ground traffic signal light group Signal lighties group i sends the initial time of fair traveling optical signal, and the initial time of fair traveling optical signal is sent relative to horizontal ground traffic signal light group qxi Interval duration is expressed as TΔg_i_qxi, wherein,
Again for example, for powered Nxi horizontal ground traffic signal light group from horizontal ground traffic signal light group qxi by starting to send out successively Go out fair traveling optical signal and present the situation that the even acceleration that initial velocity is 0 guides speed, the horizontal ground in Nxi horizontal ground traffic signal light group Traffic signal light group i sends the initial time of fair traveling optical signal, relative to horizontal ground traffic signal light group qxi send fair traveling optical signal it is initial when The interval duration at quarter is expressed as TΔg_i_qxi, wherein,When even acceleration The initial velocity v of guiding speed0Universal expression formula during more than 0 can be：
Wherein, the Tcd_xiRepresent the corresponding overlap durations of entrance lane xi, Tcd_xiBe also equal to horizontal ground traffic signal light group pxi with The interval duration of the initial time of fair traveling optical signal is laterally sent between the traffic signal light group qxi of ground.The LYD_xiRepresent entrance lane xi's Spacing (i.e. the entrance guiding section length of entrance lane xi) between stop line and crossing safety line, the LYD_xiIt is also equal to horizontal traffic above-ground Spacing between signal lighties group pxi and horizontal ground traffic signal light group qxi.The Li_qxiRepresent horizontal ground traffic signal light group i with laterally Spacing between the traffic signal light group qxi of face, the Li_qxiIt is also equal between horizontal ground traffic signal light group i and the stop line of entrance lane xi Spacing.Wherein, horizontal ground traffic signal light group i is any one the horizontal ground traffic signal in Nxi horizontal ground traffic signal light group Lamp group.
Wherein, LYD_xiAnd/or Tcd_xiValue can immobilize, also can be varied from environmental change.As a rule, for safety The consideration of aspect, the first car after the stop line of entrance lane xi sails the speed at crossing into preferably at safety range, such as speed per hour 15,000 Rice or 20 kms are exactly the safe scope of comparison.If the travel speed of first car is in safety range, then first car generally just can occur Brake in time during the emergency situations of crossing, this advantageously reduces the probability for crossing accident occur.For the consideration of these secure contexts, using the Nxi The guiding speed that the fair traveling optical signal that individual horizontal ground traffic signal light group sends is presented, sails first car the travel speed guiding of crossing into To safety range, then crossing safety 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 from startup It is exactly to obtain to the distance accelerated to needed for safe speedReference basis.Represent the corresponding overlap durations of entrance lane xi Plan initial value,The entrance for representing entrance lane xi guides the plan initial value of section length.
Wherein, LYD_xiValue is equal toTcd_xiValue is equal toOr for LYD_xiAnd/or Tcd_xi's The situation that value 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 the change of current environment factor Change to select corresponding safety coefficient, and then be based on(or) and it is currently selected with safety coefficient currently being made Tcd_xi(or LYD_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 of μ 1 (or μ 2) is for example May be referred to the environmental factorss such as weather, light intensity, the gradient and/or crossing complexity to determine.The value of μ 1 (or 1/ μ 2) can for example when fine day 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 1.2,1.3,1.5,2 or other Value) more than the value of the μ 1 (or μ 2) when fine day.Again the value of μ 1 (or μ 2) can be equal to 1 or close to 1 (example for example when light intensity is preferable As 1.1 or 1.05 or other values), when light intensity is poor, the value (such as 1.2,1.3,1.5,2 or other values) of μ 1 (or μ 2) is more than working as light The value of μ 1 when strong preferable.Again for example, when the gradient is less the value of μ 1 (or μ 2) can be equal to 1 or close to 1 (such as 1.1,1.06 or Other values), the value (such as 1.2,1.3,1.5,1.8,2 or other values) of the μ 1 (or μ 2) when the gradient is less more than when the gradient compared with The value of the μ 1 when big.For example when crossing complexity is less the value of μ 1 (or μ 2) be equal to 1 or close to 1 (such as 1.1,1.04,1.08 or Other values), and the value of the μ 1 (or μ 2) when crossing complexity is larger (as 1.2,1.3,1.5,1.7,1.9,1.8,2 or other values) More than the value of the μ 1 (or μ 2) when the gradient is less.
It is appreciated that it is to improve safety to arrange one of purpose of μ 1 (or μ 2), therefore the value of μ 1 (or μ 2) is also possible to refer to it He one or more affects safe factor to determine.Which affects the factor of safety with specific reference to, how to come true with reference to each factor for affecting safety 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 guide section length L with entrance between different periods and parking line positionYD_xi Between can have corresponding relation.For example, the corresponding parking line position of peak hours/period (such as this period L can be pre-setYD_xiFor 10 meters or its It is worth), half peak hours/period corresponding parking line position (such period LYD_xiFor 8 meters), the corresponding parking line position of idle period is (for example This period LYD_xiFor 6 meters) etc..For example can be by 7：30~9:30、17:30~20:00 delimit be peak hours/period, 0:00~6:00 delimited as the free time Period, it is half peak hours/period that other periods delimited, and certainly correspondence different application scene may also also have other to obtain Time segments division mode, herein not An another citing.
Again for example, corresponding relation, i.e. different periods can guide section length L with entrance between vehicle flowrate and parking line positionYD_xiIt Between 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, when the vehicle flowrate at crossing For 60~100 per minute when entrance guiding section length LYD_xiFor 8 meters or other values.When the vehicle flowrate at crossing is less than 30 per minute, entrance draws Lead section length LYD_xiFor 6 meters or other values, other situations are by that analogy.
Additionally, can also have corresponding relation, such as phase between the size of grade crossing, with corresponding overlapping time and entrance guiding section length To larger grade crossing, overlapping time and entrance guiding section length can be relatively large.And relatively small grade crossing, during overlap Between and entrance guiding section length can be relatively small.
When control phase place includes emptying phase place, at present some traffic specifications specify to empty phase place (crossing full red signal interval) when Length is fixed as 2 seconds, it is contemplated that the different tracks of Different Plane intersection empty length and may be not quite similar, approximately the same plane intersection The length that empties in different tracks is likely to be not quite similar, and emptying a length of particular value during phase place might not be most scientific.Therefore, it can consider according to car The length that empties in road obtains corresponding emptying phase place duration Tqk.For exampleOr work asMore than or During equal to 2 secondsAnd work asT during less than 2 secondsqk_xiValue is 2 seconds.Tqk_xiRepresent entrance car Road xi's empties phase place duration.Lqk_xiRepresent that entrance lane xi is corresponding and empty length (Lqk_xiEqual to the entrance of entrance lane xi The corresponding crossing length of guiding section length+entrance lane xi).V'lk_xiFor example equal to the minimum of the affiliated grade crossings of entrance lane xi Fast Vlk_minOr desired speed Vlk_q.Or V'lk_xiV can be equal tolk_min* μ 3 or Vlk_q* μ 3, the 3rd peace The value of overall coefficient μ 3 can be equal to 1 or more than 1 or less than 1.Specifically, the value of μ 3 for example may be referred to weather, light intensity, the gradient and/ Or the environmental factorss such as crossing complexity, determining, the concrete value mode of μ 3 refers to the concrete value mode of μ 1.
Based on T obtained from the mode of the example aboveqk_xiCan not be fixed duration 2 seconds, Tqk_xiCan be different according to concrete crossing situation And adaptive change, be so conducive to more preferably guaranteeing that vehicle is not clashed at crossing, and then be conducive to further improving the current peace in crossing Quan Xing.
Optionally, in the application some possible embodiments, methods described also includes：Terminate in the control phase place of the entrance lane xi When drive the Nxi laterally ground traffic signal light group synchronously send forbidden optical signal.Or tie in the control phase place away from the entrance lane xi Beam is also remained when emptying phase place duration, drives Nxi horizontal ground traffic signal light group synchronously to send forbidden optical signal.Or away from it is described enter The control phase place of mouthful track xi terminates also to remain when emptying phase place duration, drive described Nxi laterally ground traffic signal light group from it is described laterally Face traffic signal light group qxi starts to send forbidden optical signal successively, wherein, described in the distance among the Nxi horizontal ground traffic signal light group The initial time that laterally ground traffic signal light group qxi nearer horizontal ground traffic signal light group sends forbidden optical signal is more early, the horizontal ground Traffic signal light group pxi sends the initial time of forbidden optical signal, be later than other of the Nxi laterally in the traffic signal light group of ground any one Laterally 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 the initial time of forbidden optical signal Interval empty duration equal to the entrance boot section of the entrance lane xi.Wherein, the entrance boot section of the entrance lane xi empties duration and represents For TYD_qk_xi,Wherein, V'YD_qk_xiV can be equal tolk_maxOr Vlk_minOr Vlk_q, wherein, the Vlk_maxRepresent the Maximum speed limit of the grade crossing, Vlk_minRepresent the grade crossing Minimum speed limit, Vlk_qRepresent the desired speed of the grade crossing.Wherein, entrance boot section empties duration TYD_qk_xiE.g., less than Overlap duration Tcd_xi。Vlk_minLess than Vlk_max。Vlk_qValue space be greater than or equal to the Vlk_minAnd less than or wait In Vlk_maxAny real number, i.e. Vlk_qMore than or equal to the Vlk_minAnd less than or equal to Vlk_max。
Concrete example, for powered Nxi horizontal ground traffic signal light group from horizontal ground traffic signal light group qxi by starting successively Send forbidden optical signal and present the situation of at the uniform velocity guiding speed, then, the horizontal traffic above-ground in Nxi horizontal ground traffic signal light group Signal lighties group i sends the initial time of forbidden optical signal, and the initial time of forbidden optical signal is sent relative to horizontal ground traffic signal light group qxi Interval duration is expressed as TΔr_i_qxi, wherein,Li_qxiRepresent The horizontal ground traffic signal light group i relative to the horizontal ground traffic signal light group qxi spacing, the horizontal ground traffic signal light group i For any one the horizontal ground traffic signal light group in the Nxi laterally ground 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, drive described Nxi it is horizontal Earthward traffic signal light group synchronously sends alert traveling optical signal, terminates also to remain in the control phase place away from the entrance lane xi and empties phase place duration and add Excessively when phase place duration, described Nxi horizontal ground traffic signal light group is driven to start to send out successively from the horizontal ground traffic signal light group qxi Responding traveling optical signal, wherein, laterally ground traffic signal light group qxi is nearer described in the distance among the Nxi horizontal ground traffic signal light group The horizontal ground traffic signal light group initial time that sends alert traveling optical signal it is more early, the horizontal ground traffic signal light group pxi sends alert row light letter Number initial time, be later than other any one the horizontal ground traffic signal light groups of the Nxi laterally in the traffic signal light group of ground and send police The initial time of traveling optical signal.For example, the horizontal ground traffic signal light group pxi and horizontal ground traffic signal light group qxi sends alert row Entrance boot section of the interval of the initial time of optical signal equal to the entrance lane xi empties duration.
In actual applications, the executive agent of said method can be the signal lighties drive control apparatus such as semaphore, array driver.The application The semaphore referred in embodiment is likely to referred to as programme-controlled exchange, or traffic control signal machine, traffic signaling equipment, intersection annunciator, crossing friendship Messenger machine or crossing traffic control signal machine etc..Fig. 6 and Fig. 7 exemplified semaphore, array driver and crossroad traffic signal lamp battle array Some possible annexations of row.Specifically, semaphore or array driver can by crossroad traffic signal lamp array output drive signal come Drive control crossroad traffic signal lamp array works.In actual applications, each horizontal ground traffic signal light group can be under the control of semaphore Work.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 the start/stop time (start/stop time of the start/stop time of phase place, the excessive phase place of for example passing through Or the start/stop time of forbidden phase place etc.) determined by semaphore, the start/stop time of these phase places is recordable in the multiphase traffic time allocation that semaphore is safeguarded In table, therefore, semaphore can learn the start/stop time of the control phase place of each entrance lane, that is to say, that semaphore can learn that what moment is The upper crossing conflict control power phase place of the control phase place away from the entrance lane xi terminates also to remain overlap duration Tcd_xiWhen.And array drives Device then can from semaphore or (be connected with semaphore or by semaphore control other equipment) what moment is away from described for direct or indirect learning The upper crossing conflict control power phase place of the control phase place of entrance lane xi terminates also to remain overlap duration Tcd_xiWhen.For example, array drives Dynamic device can be based on from semaphore (or the other equipment for be connected with semaphore or being controlled by semaphore) for pass through phase place or forbidden phase place Timing signal, learns that what moment is that the upper crossing conflict control power phase place of the control phase place away from the entrance lane xi terminates also to remain overlap 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 overlap of phase place is weighed Mechanism, when terminating also to remain overlap duration away from current control phase place, just can control the next crossing conflict control power phase of current control phase place Position starts to let pass.Next crossing conflict control power phase place has begun at the end of being so achieved that current control phase place also not, realizes that crossing rushes The overlap of prominent control phase place, and then the vehicle that next crossing conflict control weighs the corresponding entrance lane of phase place is carried in entrance boot section Preacceleration, thus, speed during its arrival crossing may be of a relatively high, therefore just can be shortened by the time of the grade crossing, 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 light for allowing vehicle pass-through The time at intervals of signal is equal to and overlaps duration, thus, the vehicle on entrance lane xi draws in the safety of the Nxi horizontal ground traffic signal light group Lead descending when sailing to crossing, the upper control phase place for conflicting with the crossing of the control phase place of entrance lane xi before is over, therefore has Beneficial to causing the vehicle on entrance lane xi to collide with each other in the current vehicle that crossing does not conflict with other crossings, and then entrance lane is advantageously allowed Vehicle on xi runs over the safety at crossing and is ensured.
Illustrate below by an instantiation.Assume there is the plane cross intersection that a north-south intersects with East and West direction, it is assumed that whole The total duration of the phase cycling of plane cross intersection is fixed as 120 seconds.One phase cycling of whole plane cross intersection is plane ten Control phase place (such as north-south Through Lane, north-south left turn lane, the East and West direction straight traffic in all crossings conflict track of word intersection The control phase place in road and East and West direction left turn lane) circulate one week.The setting of the control phase place in each group crossing conflict track in traditional scheme Mode can be as shown in Fig. 5-b citings, without temporal overlap between the control phase place in each group crossing conflict track, when whole plane cross is handed over The total duration of the phase cycling of cross road mouth assumes to be fixed as 120 seconds, then north-south Through Lane, north-south left turn lane, East and West direction Through Lane Typically it is respectively 30 seconds with the control phase place in this 4 groups of crossings conflict track of East and West direction left turn lane.Assume the control phase of north-south left turn lane Position 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, exemplified north-south in Fig. 5-b The control phase place of left turn lane is 90~120 seconds.Wherein, the control phase place of north-south left turn lane includes 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 (crossing full red signal interval) about 2 seconds.In the case, it is corresponding effective Current duration can be equal to current phase place, and (2 seconds for deducting herein are regarded as driver's response time+vehicle launch time etc., can be described as leading within -2 seconds 25 seconds Line phase loses duration) (hypothesis transition phase place duration includes+available transition phase place duration for 3 seconds within about 1 second：Available transition phase place duration About 1 second+not available transition phase place duration about 2 seconds), about 24 seconds altogether.The total losses time of single control phase place (can claim control phase The transition loss duration of position) it is about 2 seconds when being equal to not available transition phase place duration about 2 seconds+empty phase place 2 seconds+current phase loss, also It is to say that the total losses time amounts to reach about 6 seconds.
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.Stop line and crossing Spacing between safety line is adapted with Chong Die duration, and then (for example, north-south Through Lane is kept straight on East and West direction to be capable of achieving crossing conflict track Track) control phase place between overlap 8 seconds.The various phase places in each group crossing conflict track arranged according to overlap mode can be such as Fig. 5-c and figure Shown in 5-d citings.
In citing shown in Fig. 5-c, so that the phase cycling total duration of whole plane cross intersection is remained fixed at 120 seconds as an 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 It is constant, then the duration of its control phase place can be by extending to 38 seconds (controls of exemplified north-south left turn lane in Fig. 5-c for original 30 seconds Phase place is 0~82 second, and the control phase place of exemplified north-south left turn lane is 82~120 seconds in Fig. 5-c), therefore effectively current duration is equal to 38 seconds-control phase place transition loss duration (not available transition phase place duration about 2 seconds+empty phase place about 3 seconds (crossing empty about 2 seconds+enter Mouthful boot section empties about 1 second)+current phase loss when be about 2 seconds, altogether about 7 seconds), about 31 seconds altogether.North-south Through Lane, East and West direction Through Lane is similar with the situation of East and West direction left turn lane.
It can be seen that, it is constant in the total duration (120 seconds) of the phase cycling of whole plane cross intersection in scene shown in Fig. 5-c citings Under the conditions of, relative lifting ((31-24)/24) ≈ 29% of effectively current duration of the single control phase place of north-south left turn lane is effectively logical The increase of row duration inevitably facilitates raising vehicle pass-through efficiency.
Shown in Fig. 5-d illustrate in, with north-south Through Lane, north-south left turn lane, East and West direction Through Lane and East and West direction left turn lane this As a example by the duration of the control phase place in 4 groups of crossings conflict track is fixed to 30 seconds, in this case, through crossing conflict control phase place is weighed Overlap, as Fig. 5-d citing shown in, the phase cycling total duration of whole plane cross intersection shorten to 96 seconds by 120 seconds.
In scene shown in Fig. 5-d citings, shorten by a relatively large margin (by 120 seconds in the total duration of the phase cycling of whole plane cross intersection Shorten to 96 seconds) in the case of, due to north-south Through Lane, north-south left turn lane, East and West direction Through Lane and East and West direction left turn lane this The duration of the control phase place in 4 groups of crossings conflict track does not all shorten, therefore the effectively current duration of corresponding control phase place does not shorten.Due to The total duration of the phase cycling of whole plane cross intersection is shortened, then can be pacified in same duration scope (such as within an hour) The phase cycling quantity of the whole plane cross intersection of row can also must with a larger increase, the corresponding effectively current duration of so same duration scope So can increase, the increase of effectively current duration inevitably facilitates raising vehicle pass-through efficiency.It can be seen that, some technical schemes of the embodiment of the present application exist On the basis of not shortening the effectively current duration of single control phase place, plane cross intersection phase cycling can be relatively much shorter using total duration Minor cycle, so advantageously account for people and plane cross intersection large period is denounced, because in traditional scheme, in order to reduce control phase The transition loss duration of position accounts for the proportion of control phase place duration, the means for generally adopting be by the phase cycling of plane cross intersection it is total when Length arrange very long, the total duration of the single phase cycling of such as some plane cross intersections is even up to 240 seconds, this cause pedestrian and The time of the red lights such as vehicle is all very long, this to wait red light duration to challenge people's tolerance limit sometimes, causes extensively to be denounced by people.
Overlap duration (i.e. preaceleration duration) in citing shown in Fig. 5-c and Fig. 5-d with time upper adjacent crossing conflict control power phase place was as 8 seconds As a example by illustrating, overlap duration and be alternatively other durations certainly, for example can for 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.With control phase in citing shown in Fig. 5-c and Fig. 5-d Position is including current phase place, transition phase place and empties as a example by phase place to illustrate, certainly, control phase place is also likely to be other groups illustrated in Fig. 2-c Into form, such as control phase place may include current phase place and empty phase place, but not include transition phase place.Control phase place is other composition forms Corresponding embodiment can be by that analogy.
As a whole, implement the scheme of the embodiment of the present application, can immobilize in the total duration of the phase cycling of whole plane cross intersection On the premise of it is relative lift effectively current duration, or whole plane cross can also be shortened on the premise of single control phase place duration is constant hand over The phase cycling total duration of cross road mouth.Overlap mechanism and the entrance boot section of phase place are weighed by introducing crossing conflict control, not only contributes to offset control The transition loss duration of system power phase place, and be conducive to greatly improving speed of the vehicle by crossing.It can be seen from time=distance/speed, in phase Speed is faster in the same time, then the vehicle for passing through is also more, and traffic efficiency is also higher.The technical scheme of the embodiment of the present application with by adopting Take some traditional schemes of prolongation phase cycling total duration to reduce the transition loss duration proportion of control phase place to compare, not only can significantly reduce whole The phase cycling total duration of individual plane cross intersection, and relatively the red light waiting time is shortened, advantageously reduce fuel consumption and waste gas Discharge capacity.
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 intersection waits less 30 Second red light, the average 1 liter of gasoline per hour of fuel consumption is calculating during idling, then calculated with 1,000,000, certain city car, more than one hundred million units can be saved every year Fuel oil.For example, * 100 ten thousand=15,000,000 liters of (5*0.5 minutes * 1 liter/60 minutes) * 360 days.Assume that per liter of oil is calculated by 7 yuan, every year 15,000,000 liters of * 7 yuan=105,000,000 yuan of oil can be saved.This has just saved social resources while traffic efficiency is improved.
Further, implement the engineered of the embodiment of the present application scheme to be easier, original means of transportation also can retain substantially, such as original Take pictures sensing etc. facility can be continuing with substantially.The start/stop time that each group crossing conflict control weighs phase place is mainly adjusted, by quilt in prior art It is arranged at after the stop line of the safe line position in crossing (such as the set location of horizontal ground traffic signal light group pxi) is carried out and moves so that crossing safety Line and stop line (such as the set location of horizontal ground traffic signal light group qxi) are separated on locus, between stop line and crossing safety line Region form entrance boot section.Further, because stop line is relatively distant from crossing, then just basic without worrying again during vehicle start Have pedestrian to pop out to come from crossing, 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 certain People's car separation without mutual interference is realized in degree.
Further, because in the conventional technology, the phase cycling total duration of grade crossing is generally all very long, causes the waiting time It is very long, and the duration of single control phase place is also longer.When the distance between two grade crossings are closer, vehicle is easily caused to exist It is detained in crossing, can thus affects the vehicle that corresponding next one control phase place is let pass by crossing, so as to cause congestion to occur, is commonly called as Rush green light.The big traffic congestion of traffic in misty rain day is also due to caused by this reason mostly.After implementing some technical schemes of the application, due to having Beneficial to the phase cycling total duration for shortening grade crossing, thus advantageously reduce and rush green light phenomenon.Meanwhile, grade crossing lane Phase total duration significantly shortens, and can make the relative reduction of public transit vehicle that single phase cycling is let pass, and advantageously reduces the public train of bus platform Phenomenon.
