Each direction of present embodiment crossroad is provided with an Application on Voiceprint Recognition device 8, can be positioned at the next door of second vehicle detector 5, with a certain distance from the crossing, makes the variation of the free processing signals lamp of controller.
Step 1: the road in suburb usually vehicle is less, in east, south, west, when the north four direction does not all have vehicle pass-through, or signal lamp all is set to red light when the traffic lights initialization of crossing, controller 4 is waited for the signal that receives each vehicle detector, all first vehicle detectors and second vehicle detector pass through the zero clearing of vehicle count value, this is an original state.
Step 2: certain track on certain direction begins to have vehicle to sail the crossing into, sail into and have the track of conflict all not have vehicle with this track of this direction, second vehicle detector 5 that is assumed to be the x track of A direction detects vehicle at first and sails the crossing signal into, and signal sent to controller 4, representative has car to sail the crossing into, controller 4 receives that the signal lamp 1 in control A direction x track behind the signal is converted to green light, and control and this A direction x track have the track of conflict to keep red light.Wherein the A direction can be any direction in east, south, west, the north four direction, and the x track can be any track in left turn lane, Through Lane or the right-turn lane.The signal lamp rule change of 4 directions is identical, all the determining step of follow procedures 2.
Wherein, be defined as about the conflict track:
For south to Through Lane, the track of conflict is: three tracks of east orientation, west to Through Lane and the left turn lane of left turn lane, north orientation, all the other tracks for not conflicting;
For south to left turn lane, the track of conflict is: the Through Lane of the Through Lane of east orientation and left turn lane, north orientation and right-turn lane, west to Through Lane and left turn lane, all the other are the tracks of not conflicting;
For south to right-turn lane, the track of conflict is: the left turn lane of north orientation, west to Through Lane, all the other are the tracks of not conflicting;
For the north to Through Lane, the track of conflict is: the west to three tracks, the left turn lane of south orientation, the Through Lane and the left turn lane of east orientation, all the other tracks for not conflicting;
For the north to left turn lane, the track of conflict is: the west to Through Lane and the Through Lane and the left turn lane of the Through Lane of left turn lane, south orientation and right-turn lane, east orientation, all the other tracks for not conflicting;
For the north to right-turn lane, the track of conflict is: the left turn lane of south orientation, the Through Lane of east orientation, all the other are the tracks of not conflicting;
For east to Through Lane, the track of conflict is: three tracks of north orientation, west to left turn lane, the Through Lane and the left turn lane of south orientation, all the other tracks for not conflicting;
For east to left turn lane, the track of conflict is: the Through Lane of north orientation and left turn lane, west to Through Lane and the Through Lane and the left turn lane of right-turn lane, south orientation, all the other tracks for not conflicting;
For east to right-turn lane, the track of conflict is: the west to left turn lane, the Through Lane of south orientation, all the other tracks for not conflicting;
For the west to Through Lane, the track of conflict is: three tracks of south orientation, the left turn lane of east orientation, the Through Lane and the left turn lane of north orientation, all the other are the tracks of not conflicting;
For the west to left turn lane, the track of conflict is: the Through Lane and the left turn lane of the Through Lane of the Through Lane of south orientation and left turn lane, east orientation and right-turn lane north orientation, all the other are the tracks of not conflicting;
For the west to right-turn lane, the track of conflict is: the left turn lane of east orientation, the Through Lane of north orientation, all the other are the tracks of not conflicting.
In the process of step 2, with the signal lamp variable condition in the track of A direction x track conflict and the signal lamp state in A direction x track be related, but and the signal lamp variable condition in the track of not conflicting, A direction x track can keep relatively independent with the signal lamp variable condition in A direction x track, controller can parallel control A direction x track and with the signal lamp in its track of not conflicting, promptly the road operation conditions in A direction x track can be irrelevant with the track of not conflicting with A direction x track.
For example, A direction x track has vehicle to drive towards the crossing, and controller makes signal lamp become green light, and and the B direction y track of not conflicting, A direction x track also have vehicle to drive towards the crossing, controller does not need to consider the control procedure in B direction y track yet follow procedures 2 simultaneously whether A direction x track is green light.Controller can be handled and control a plurality of control signal inputs that do not conflict simultaneously, can control the state variation of a plurality of signal lamps simultaneously.In addition, have vehicle to drive towards the crossing in A direction x track, signal lamp becomes under the situation of green light, can be according to the track different situations, and controller is controlled simultaneously, makes the signal lamp in the track of not conflicting with A direction x track also all become green light, perhaps keeps red light.
Step 3: 4 pairs of tracks that are in green light phase of controller are monitored, suppose it is A direction x track, judge first vehicle detector 3 in A direction x track and the signal of second vehicle detector 5 by monitoring, and the signal of second vehicle detector 5 in the track of conflicting is arranged with A direction x track, be converted to red light after the green light flavescence lamp flicker in control A direction x track three times.Concrete control procedure can for:
(1) better simply situation as shown in Figure 4: after second vehicle detector 5 from A direction x track detects first setting-up time that first car pick up counting by the crossing signal, be converted to red light after the signal lamp 1 flavescence lamp flicker in controller 4 control A direction x tracks three times.This situation is no matter the vehicle on this track is mostly to be few, also regardless of the simple process whether car is arranged on other tracks, just changes lamp to the time.
(2) can also be better simply situation as shown in Figure 5: carve at a time, first vehicle detector, the 3 detected number of signals in A direction x track equal second vehicle detector, 5 detected number of signals, then are converted to red light after the greensignal light flavescence lamp flicker in controller 4 control A direction x tracks three times.This situation is that this track just became red light after the vehicle in track such as x such as direction such as A such as grade all passed through.
(3) for the comparatively complicated situation of considering the conflict track, as shown in Figure 6, concrete control method can for:
If second vehicle detector 5 in A direction x track has detected n car altogether and sailed crossing (n 〉=1) in a period of time, second vehicle detector 5 detects first car and sails into behind the signal of crossing not detect to first vehicle detector 3 in A direction x track following 3 kinds of situations are arranged in the time range of n car by the crossing signal:
(31) the simplest situation: sail the crossing signal into if having second vehicle detector 5 in the track of conflicting not detect vehicle with A direction x track, then first vehicle detector 3 in this A direction x track detects n car by behind the signal of crossing, controller 4 control signal lamps are converted to red light after the flavescence lamp flicker three times again, n the car that promptly waits A direction x track got back to original state all by the lamp that reddens behind the crossing; Perhaps reach detect first setting-up time that first car pick up counting by the crossing signal from second vehicle detector 5 in A direction x track after, be converted to red light after the greensignal light flavescence lamp flicker in controller 4 control A direction x tracks three times, the situation of this situation and Fig. 4, Fig. 5 is similar.
(32) if second vehicle detector 5 in A direction x track detects signal, red light does not reach second setting-up time after converting green light to, and there is the track of conflicting to have second vehicle detector 5 to detect vehicle with A direction x track and sails the crossing signal into, then when reaching second setting-up time, convert red light to after the green light flavescence lamp flicker in controller control A direction x track three times.For example: setting second setting-up time is 30s, then after the red light in A direction x track converts green light 30s to, even this track also has vehicle not pass through the crossing, the also green light lamp that reddens, transference A direction x track has the vehicle that will pass through on the track of conflict to pass through, and begins to pass through after A direction x track reddens lamp such as B direction y track.
(33) if the red light in A direction x track convert to surpassed second setting-up time behind the green light after, there is the track of conflicting to have second vehicle detector 5 to detect vehicle with A direction x track and sails signal into, then convert red light to after the green light in the A direction x track flavescence lamp flicker immediately three times.For example: second setting-up time of setting is 30s, the red light in A direction x track converts in the green light 60s, this track has car current always, and have the track of conflicting not have vehicle to sail into A direction x track, then A direction x track is green light in this 60s always, but when the red light in A direction x track converts green light 60s to, there is the B direction y track of conflicting to have car to sail into, then converts red light to after the green light in the controller control A direction x track flavescence lamp flicker immediately three times with A direction x track.
Step S4: 4 pairs of controllers are in the conflict track in the track of green light phase and monitor, if B direction y track is with A direction x track the track of conflicting to be arranged, and be that the signal lamp in A direction x track becomes the first track that has vehicle to sail into behind the green light, then after the signal lamp in A direction x track became red light, the signal lamp in controller 4 control B direction y tracks at first was converted to green light.If there is a plurality of conflicts track to have vehicle to sail into, variable signal lamp sequentially then.
For example: A direction x track at first converts green light to, all successively there is vehicle to enter on B direction y track, track of conflicting and the C direction z track with A direction x track, and B direction y track and C direction z track also are conflicting tracks, according to step 4, B direction y track is after A direction x track becomes red light, at first be converted to green light, begin to pass through, and the rule of follow procedures 3, C direction z track still keeps red light, equally according to step 4 owing to also conflict with B direction y track, C direction z track is converted to green light after B direction y track becomes red light, begin to pass through.If all successively have vehicle to enter on B direction y track, track of conflicting and the C direction z track with A direction x track, but B direction y track and C direction z track are not conflicting track, then according to step 4, B direction y track at first is converted to green light after A direction x track becomes red light, begin to pass through, and the rule of follow procedures 3, C direction z track can be by controller according to step 3 parallel processing owing to not conflicting with B direction y track at this moment, convert green light to, also current simultaneously.
Step S5: after controller 4 judges that the detection signal of first vehicle detector 5 of all directions of crossing is counted detection signal that sum equals all second vehicle detector 3 and counted sum, the crossing is in no vehicle pass-through state, first vehicle detector 3 and second vehicle detector 5 are counted zero clearings, return to the original state of step S1.
For the crossing traffic control system that walk button 12 is installed (flow process is not shown), the walk track is equivalent to Through Lane, and the effect that second vehicle detector 5 of the signal of walk button 12 and Through Lane detects signal is identical.When not having vehicle pass-through on the conflict track of the Through Lane relevant with walk button 12, walk button 12 1 is pressed, and controller just makes signal lamp become green light; If the conflict car Dao Shangzhen of the Through Lane relevant with walk button 12 has vehicle pass-through, then to control according to the process of step 3 and step 4, the signal of walk button 12 is equivalent to the signal of second vehicle detector 5.Difference is, when the signal lamp of indication walk turns green after, always when the 3rd setting-up time arrives, just become red light, the assurance pedestrian can have time enough to pass through the crossing.
For the crossing traffic control system that Application on Voiceprint Recognition device 8 is installed, it is all unimpeded to need all tracks of direction that special vehicle passes through, and other directions all give way.If having detected special vehicle, passes through by the Application on Voiceprint Recognition device 8 of crossing A direction, Application on Voiceprint Recognition device 8 sends a signal to controller 4, change red light into after the green light flavescence lamp flicker of other three directions that controller 4 control A directions are outer three times, former is remaining unchanged of red light, and the signal lamp in all tracks of A direction becomes green light.And carve at a time, after the detected number of signals sum of first vehicle detector of this A direction equaled the detected number of signals sum of second vehicle detector, promptly A direction vehicle was all by behind the crossing, and the signal lamp of controller control A direction recovers red light.
For the crossing of detecting demand violating the regulations is arranged, with second vehicle detector 5 be installed in each track of all directions, crossing be used to identify in the solid line mark scope of forbidding changing trains, even second vehicle detector 5 left by vehicle, and then explanation has entered the solid line marking road section that can not change trains.This crossing traffic control system also comprises the steps: to sail the crossing signal into if second vehicle detector 5 in A direction x track detects m vehicle, m 〉=0 wherein, but first vehicle detector, the 3 detected number of signals in A direction x track are greater than m, illustrated that vehicle is changing on this track, then sent the signal that has car violating the regulations for remote monitoring main frame 2 by controller 4.Afterwards, the operator on duty of monitoring host computer end can transfer the video data of this period from DVR 6, search vehicle violating the regulations, and definite type of violation, punishes.
For example: second vehicle detector in the x track of A direction detects the signal that 5 cars pass through, second vehicle detector in the y track of A direction detects the signal that 3 cars pass through, but, certain constantly, first vehicle detector in the y track of A direction detects the signal that 4 cars pass through, surpass the detected number of signals of this track second vehicle detector this moment, then explanation has vehicle to change on this y track, controller 4 sends the signal that has car violating the regulations for remote monitoring main frame 2, the operator on duty of monitoring host computer end transfers the video data of this period from DVR, search vehicle violating the regulations, if find that vehicle only is that solid line changes enforcement, then give solid line and change punishment, if find that vehicle was from being the track that green light is changed in the track of red light originally, but the travel direction that the travel direction behind the crossing is still forbidden for red light illustrates that this vehicle utilizes the green light vehicle in a disguised form to make a dash across the red light, the punishment of then making a dash across the red light.
Crossing for limited high request, this crossing traffic control system also comprises the steps: to be arranged on the superelevation detecting device 10 in each track of all directions, crossing if detect the superelevation signal, then send to controller 4, the superelevation alarm 11 of controller 4 these directions of control is reported to the police, give the driver with caution, and send the signal that the car superelevation is arranged for remote monitoring main frame 2, the prompting operator on duty of Surveillance center, can notify traffic police on duty, vehicle is tackled inspection.
In addition, when the signal lamp in direction track, crossing was red light, first vehicle detector 3 in this this track of direction detected signal, illustrated that this track has car to make a dash across the red light.For example: the x track of A direction is a red light, and this moment, first vehicle detector 3 in this track should not have vehicle by signal, in case find have vehicle to pass through signal, has illustrated that car rushed red light.After then this moment, controller 4 received the signal that first vehicle detector 3 sends, send for the Surveillance center of far-end to have the car signal that makes a dash across the red light, Surveillance center can transfer the video data in x track of the A direction of this period from DVR 6, search the vehicle that makes a dash across the red light.Because what video camera was taken is one section video, is not photo, therefore for the trailer of lengthening, this crossing traffic system also can capture the license plate number that adds long vehicle.
Moreover, system of the present utility model can monitor the crossing vision signal at the monitoring host computer end in real time by traffic control department, need the situation of temporary changes signal lamp lighting time to carry out real time remote to some controller is controlled, thus the bright lamp situation of control signal lamp.
The above only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented with this, and all simple conversion of doing according to the utility model claim and description all should still belong to protection domain of the present utility model.
