Id information, facilitate the message transmission between vehicle and data analysis, the information of communication module transmission has the address information of vehicle, car
Traffic direction information, whether agree to after to conflict track vehicle traffic information, agree to the letters of other track vehicle pass-throughs
Breath etc. various message are all transmitted and received by communication module.Information of vehicles on each track is by processor
Shown after reason on display module, such as allow to pass through, refuse current, waiting time, whether be open to traffic also has vehicle
Message, can show in display module.The display and transmission of various message are sent after processor is handled
Instruction could carry out, the criterion of processor processing vehicle pass-through, which is arrived first, to get ahead and the criterion such as concurrent lane, these
Criterion hereinafter describes in detail.
Timing unit, the waiting time of registration of vehicle are provided with processor, and is sent by communication module to crossing vehicle
Waiting time result is so as to remind remaining vehicle this car stand-by period to reach most long conflict track waiting time, being currently running
Vehicle by intersection after, follow-up vehicle is out of service, and the vehicle for having waited more than maximum waiting time passes through, and keeps away
Exempt from the vehicle arrived first because the vehicle fleet size in this track is few, and in wait state always；Either due to this track
Vehicle fleet size is few, and adjacent phase track is excessively in current state, and this track vehicle is constantly in wait.
Due to the Morphological Diversity of intersection, illustration object is used as from common crossroad in the present invention.Such as Fig. 2
It is shown, crossroad lane markings it is the track of " 0 "-" 7 " number 8 in figure, according to traffic route rule, if in different cars
The vehicle in road can be travelled and passed through in intersection simultaneously, then these tracks are referred to as " concurrent " track.On the other hand, it is right
If these tracks can not be defined as the track that " conflicts " by the vehicle in different tracks simultaneously in intersection traveling.
In existing traffic traveling, simply lanes of single-phase（Such as coordinate system, north and south is a phase, and thing is
One phase）, when have ignored the lane of current phase, if only straight trip or left-hand bend vehicle, will waste other
The stand-by period in phase track, because the current of the track in phase adjacent can also be allowed simultaneously.Such as No. 0 lane state
In, No. 1 track is also to allow current state, but if not having vehicle in No. 1 track, can allow the vehicle in other tracks
It is current that track utilization rate is increased with this, reduce the stand-by period of other vehicles, now No. 3 tracks or No. 4 tracks be also can be with
What operation was passed through, while not interfering with traffic order, further promote traffic circulation.Each track allows simultaneously open situation such as
Shown in table 1, as shown in Table 1, non-duplicate situation has 12 kinds, be respectively " 0,1 ", " 0,3 ", " 0,4 ", " 1,5 ", " 1,6 ", " 2,3 ",
" 2,5 ", " 2,6 ", " 3,7 ", " 4,5 ", " 4,7 " and " 6,7 " etc. 12 kinds of concurrent transport conditions, if making full use of road, maximum
Utilize road to limit, it will substantially reduce the traffic stand-by period.
Table 1 can allow current concurrent track
As shown in figure 3, a kind of control method of crossing traffic system, its step includes：
Step 1: track vehicle enters crossing waiting area, send request and pass through message.With traffic direction message.Vehicle
Enter into intersection after waiting area, processor sends request by message by communication module, and request passes through in message
Include traffic direction message, wait the processing information of surrounding vehicles.
Step 2: whether the vehicle receives the refuse information of surrounding vehicles.
Step 3, is continued waiting for if refuse information is received.When vehicle is waited, when timing unit record is waited
It is long, once more than the maximum waiting time of default, communication module sends waiting time prompting to crossing surrounding vehicles, other
Vehicle stops entering in wait state, and waiting-timeout vehicle passes through, it is ensured that the circulation and activity of road.
Step 4: being run if refuse information is not received by by crossing.If vehicle is not received by for a long time
Refuse traffic information, then prove there is no vehicle around intersection, vehicle operation passes through intersection.So save without car
The time of traffic lights is also waited for, improve operational efficiency, it is to avoid the avoidable stand-by period.
In vehicle operation, the display and transmission of various message are all the instruction ability sent after processor is handled
Carry out, the criterion of processor processing vehicle pass-through, which is arrived first, to get ahead and the criterion such as concurrent lane, is to figure as shown in Figure 4
3 supplement, vehicle is when by intersection, and processor determines whether this track Following Car according to mutual information of vehicles
, follow message to following vehicle if this track following vehicle is then sent, vehicle is run by crossing together；If this car
Road does not have following vehicle, and track vehicle is continued to run with by crossing.While following vehicle is run, processor can also be according to mutual
Between information of vehicles determine whether the vehicle in concurrent track, if so, then sending message of concurrently passing through, concurrent track vehicle is same
Shi Yunhang is by intersection, if without concurrent track vehicle, track vehicle is continued to run with by crossing.The hair of concurrent message
The maximum utilization rate that ensure that track is sent, has been saved the stand-by period of surrounding vehicles, and the form of intersection can be appointed
Meaning, do not influenceed, do not constrained by centerized fusion device by crossroad form.
