For crossing basic information, because crossing basic information illustrates access crossing infrastructure situation, crossing Basic information will not change.Therefore, crossing basic information can be by the preparatory typing traffic signal controlling machine of technical staff.When When crossing infrastructure changes, for example, road maintenance, road change its course with road broadening etc., can be by technical staff again Typing traffic signal controlling machine.For real-time traffic flow information, because traffic signal controlling machine acquisition is real-time traffic flow information, institute With traffic signal controlling machine corresponding temporal information can be added in real-time traffic flow information.

After getting crossing basic information and real-time traffic flow information, traffic signal controlling machine is according to same access crossing pair Virtual number, crossing basic information and the real-time traffic flow information answered, generate the crossing parameter list at the access crossing, the crossing of generation Parameter list is stored into memory space corresponding with access crossing.

Optionally, virtual number includes crossing mark, subordinate mark and verification information.Crossing mark is for uniquely indicating one A access crossing.For example, crossing mark is the combination of crossing title and public security private code.Subordinate mark is used to indicate access road The traffic signal controlling machine of mouth.For example, the device numbering of traffic signal controlling machine.In the next steps, traffic signal controlling machine It needs to communicate between traffic signals server and transmits data.When establishing communication, traffic signal controlling machine and traffic signals Server settings one is used for the information of safety verification, such as Hash codes.The information, that is, above-mentioned verification information.

Illustratively, as shown in figure 4, it illustrates the crossing parameter lists that two are accessed crossing.Crossing parameter list 30 and road Mouth parameter list 31 is two crossings of same traffic signal controlling machine control: crossing A and crossing B respectively.The corresponding virtual volume of crossing A Numbers 301 are as follows: A-0bdec304-hash(L1).The corresponding virtual number 311 of crossing B are as follows: B-0bdec304-hash(L1).

Step 207, the process resource obtains the crossing at each access crossing being connected with the traffic signal controlling machine Parameter list.

In the step, process resource obtains the crossing parameter list at each access crossing, then can obtain each access crossing Crossing basic information and real-time traffic flow information.

Step 208, the process resource is according to the crossing in the spacing distance at neighboring access crossing, the crossing parameter list Basic information and the real-time traffic flow information, generate Coordinated Control Scheme, and the Coordinated Control Scheme is used to indicate the traffic Signal controlling machine controls the traffic signals coordinated operation at multiple access crossings.

After the crossing parameter list for generating each access crossing, traffic signalization equipment can be according in the parameter list of crossing Crossing basic information and real-time traffic flow information determine the corresponding Coordinated Control Scheme in access crossing.The Coordinated Control Scheme is used for Indicate that traffic signal controlling machine controls the traffic signals at corresponding crossing.For example, accessing the machine of the south-north direction at crossing for one Motor-car traffic lights, Coordinated Control Scheme can indicate the automobile traffic signal lamp all directions green light lighting time and Bright light sequence.

Traffic signal controlling machine can determine the road conditions at access crossing according to crossing basic information, for example whether someone's row Whether road has non-motorized lane, whether has individual right-turn lane etc..Traffic signal controlling machine is in conjunction with real-time traffic flow information Determine above-mentioned Coordinated Control Scheme.

In a kind of possible embodiment, Coordinated Control Scheme includes phase subscheme, phase sequence subscheme, sub- timing side Phase difference between case and sub- timing scheme.The phase that phase subscheme is used to indicate crossing divides.The phase at crossing refers to The travel route of crossing all directions.The phase that phase sequence subscheme is used to indicate crossing executes sequence.Therefore, phase sequence scheme is companion It is generated jointly with phasing scheme.The execution sequence of phasing scheme can be set according to the road conditions at different crossings, and phasing scheme Execution sequence also have a preset rule.Traffic signal controlling machine can be according to the crossing function category in the basic information of crossing Property, road shunting canalization information and signal lamp configuration information determine phase subscheme and phase sequence subscheme.Wherein, crossing function Attribute is used to indicate the function status at access crossing, is main road or secondary for example whether through street, is major trunk roads or subsidiary road Road.Road shunting canalization information is used to indicate the graticule of left-hand rotation, straight trip and the right-hand rotation at access crossing, such as the right-hand rotation at part crossing With straight trip in same graticule.Signal lamp arrangement situation is used to indicate the signal lamp arrangement at access crossing, for example whether there is right-hand rotation Lamp.

Illustratively, access crossing is the standard crossroad in a city, and road intersection is major urban arterial highway, each side Complete to canalization, signal lamp outfit is complete, then the phase subscheme that traffic signal controlling machine determines is four phasing scheme of standard: phase Position 1(trunk 1 is kept straight on);1 left/right rotation of phase 2(trunk);Phase 3(trunk 2 is kept straight on);2 left/right rotation of phase 4(trunk).Accordingly Phase sequence subscheme are as follows: 3 → phase of phase 1 → phase, 2 → phase 4.

Sub- timing scheme in Coordinated Control Scheme is used to indicate the signal period of various types of signal and signal in traffic signals Duration.The sub- timing scheme that traffic signal controlling machine determines is really optimum signal timing scheme.The optimum signal timing scheme It is to ensure that vehicle passes through the delay time at stop shortest timing scheme of intersection.Therefore, traffic signal controlling machine is according to access crossing Real-time traffic flow information, above-mentioned sub- timing scheme is determined using Robert Webster (Webester) timing method.

Phase difference between sub- timing scheme is according to the spacing distance at neighboring access crossing and according to real-time traffic flow information Calculated average speed can determine that the phase difference that each access crossing traffic signal is let pass, the phase difference are used for Indicate the time interval that upstream and downstream crossing green light is let pass.Under specific green light clearance time interval, it is capable of forming certain green Wave passage effect, reliably promotes passage speed, reduces stop frequency.

In alternatively possible embodiment, Coordinated Control Scheme further includes period schemes.The period schemes refer to root According to the set of different period different sub-sequence schemes generated.For the same crossing, because of vehicle in different time sections Traffic status so the sub- timing scheme in different time sections is also different.For example, morning peak period and evening peak period, with And flat peak period and night-time hours.

Traffic signal controlling machine first determines the corresponding access crossing of each Coordinated Control Scheme, then by the coordination at each crossing Control program is assigned in corresponding output lamp group, executes the scheme of the output lamp group at each access crossing of control.

Optionally, traffic signal controlling machine is no longer on the basis of single crossing, but generates to each access crossing One Coordinated Control Scheme.Also, multiple crossings of traffic signal controlling machine access are usually adjacent intersection.Therefore, it hands over Messenger control machine can acquire car flow information in real time, and the Coordinated Control Scheme docked into crossing is corrected in real time.Phase Compared with the mode for being sent to traffic signals server and being modified, due to being not necessarily to communication transmission information, and the access road handled The negligible amounts of mouth, so can be more promptly modified to Coordinated Control Scheme.For the burst shape on traffic route Condition, such as traffic accident, the mode that traffic signal controlling machine is modified according to the car flow information acquired in real time can be according to fast Speed, the traffic signals for effectively adjusting access crossing.

In method provided by the embodiments of the present application, virtualization manager is empty by the way that storage chip is divided into multiple storages Between, microprocessor is divided into multiple computing resources and process resource, so that each access crossing corresponds to independent storage sky Between and computing resource, computing resource each access crossing is obtained by the calculating to crossing basic information and original car flow data Real-time traffic flow information each independent crossing parameter in access crossing is generated according to crossing basic information and real-time traffic flow information Table.Process resource according in the spacing distance at neighboring access crossing, the crossing parameter list crossing basic information and the reality When car flow information, generate Coordinated Control Scheme, rather than on the basis of single crossing determine traffic signals control program;And And it is not necessary that each intersection information is sent to traffic signals server, and Coordinated Control Scheme is generated by traffic signals server, But each access crossing is all directly directly generated into Coordinated Control Scheme by traffic signal controlling machine as independent crossing, from And the traffic signals that all crossings are controlled on the basis of a crossing are avoided, it can be improved the current effect of traffic of traffic intersection Rate.

Separate unit traffic signal controlling machine usually can access limited access crossing, such as 1 ~ 4, and its internal setting There is the lamp of the output lamp group for controlling each access crossing to drive plate, in order to which each traffic signal controlling machine is accessed crossing Intersection information is associated, realizes that the purpose at control more multiple access crossing, another embodiment of the application are provided one kind and set based on separate unit The method of standby coordinated control Multiple Intersections traffic signals, Fig. 5 show using this method schematic diagram of a scenario, wrap in the application scenarios It includes: multiple crossings 101, traffic signal controlling machine 102 and traffic signals server 103.Traffic signal controlling machine 102 and traffic are believed Establishing between number server 103 has communication connection.

Traffic signal controlling machine 102 is the equipment for controlling the traffic signals at least one crossing 101, internal part Plate etc. is driven including power supply, communication chip and lamp.In this application, the crossing 101 for accessing traffic signal controlling machine 102 is also referred to as Access crossing.Traffic signal controlling machine 102 can access multiple crossings 101, can also access single crossing 101.

Traffic signals server 103 is the server for monitoring and managing traffic signal controlling machine 102.Traffic signals clothes The business operation of device 103 has traffic signalization to manage platform.It is for managing traffic signals that the traffic signalization, which manages platform, Software program.Traffic signals server 103 can manage multiple traffic signal controlling machines 102.

When controlling the traffic signals at crossing 101, traffic signal controlling machine 102 is set according to the actual conditions at crossing 101 The Coordinated Control Scheme of traffic signals.Coordinated Control Scheme is monitored and is audited by traffic signals server 103.If coordinating Control program needs to adjust, then traffic signals server 103 corrects Coordinated Control Scheme.Traffic signal controlling machine 102 is according to repairing The traffic signals at the scheme control crossing 101 after just.

Fig. 6 is referred to, it illustrates another embodiment offers of the application based on single device coordinated control multichannel oral sex The work flow diagram of the method for messenger, this method may include the following steps:

Step 401, according to crossing basic information in the spacing distance at neighboring access crossing, the crossing parameter list and described Real-time traffic flow information, after generating Coordinated Control Scheme, the process resource respectively joins the crossing at each access crossing Number table and Coordinated Control Scheme, are sent to traffic signals server.

Traffic signal controlling machine, can be directly according to coordination after determining the corresponding Coordinated Control Scheme in each access crossing Control program controls the traffic signals at each access crossing.But in traffic administration the wagon flow control at crossing usually also with The adjacent intersection at the crossing is related.Because the wagon flow at a crossing is not only influenced by the road conditions at the crossing itself, also suffer from The vehicle flowrate of adjacent intersection influences.For example, if adjacent intersection vehicle congestion occurs and causes vehicle flowrate smaller, the wagon flow meeting at crossing It reduces.Therefore, it is necessary to the Coordinated Control Schemes determined to traffic signal controlling machine to be modified.Because traffic signal controlling machine is only It can control limited crossing, so the adjacent intersection at a crossing may be controlled by other traffic signal controlling machines.Therefore, individually Traffic signal controlling machine is unable to complete the amendment to Coordinated Control Scheme.Therefore, traffic signal controlling machine is respectively by each access The crossing parameter list and Coordinated Control Scheme at crossing, issue traffic signals server.It is connect by the amendment of traffic signals server is each Enter the Coordinated Control Scheme at crossing.

Traffic signal controlling machine is the individual Coordinated Control Scheme that each access crossing is all set, so as to more precisely Control the traffic signals at each crossing.Therefore, traffic signals server corrects Coordinated Control Scheme, it is also desirable to the same traffic The Coordinated Control Scheme at each crossing under signal controlling machine is modified.It is existing in the related technology, traffic signalization Machine on the basis of single crossing because carry out the control of traffic signals, in request traffic signals server Correction and Control scheme When, what is sent to traffic signals server is also crossing basic information, real-time traffic flow information and the control program at single crossing.In In the embodiment of the present application, the crossing parameter list that one is accessed crossing and Coordinated Control Scheme are encapsulated as one by traffic signal controlling machine Group data information, then the crossing parameter list at each access crossing and Coordinated Control Scheme are sent to traffic signals service respectively Device, so that traffic signals server corrects the Coordinated Control Scheme at each access crossing.Therefore, for single traffic signals control Machine processed, what traffic signals server received is no longer the control program at the single crossing under traffic signal controlling machine control, But it is virtual after each access crossing crossing parameter list and Coordinated Control Scheme.Therefore, traffic signals server can be known Each access crossing not under traffic signal controlling machine control all manages at each access crossing as independent crossing, And then the Coordinated Control Scheme at each access crossing is modified.

Step 402, the traffic signals server according to it is each it is described access crossing crossing parameter list, and, it is described The spacing distance and real-time traffic flow information at other neighboring access crossings of traffic signals server access, generate revised coordination Control program.

Optionally, the amendment of the Coordinated Control Scheme at corresponding access crossing, traffic signals server is first according to crossing parameter Crossing basic information in table determines the relationship between adjacent intersection.For example, according to crossing centre coordinate determine adjacent intersection it Between spacing, determined according to crossing speed limit section between adjacent intersection when speed difference, adjacent intersection between section number of track-lines, vehicle Road width and saturated capacity etc..After the relationship between adjacent intersection that determines, traffic signals server is further according to adjacent intersection reality When car flow information, correct the Coordinated Control Scheme at corresponding crossing.For example, traffic signals server is according between two adjacent intersections Spacing and crossing between section on driving vehicle average speed per hour, calculate upstream crossing vehicle let pass after reach downstream road The time required to mouthful, the phase difference between above-mentioned adjacent intersection is obtained.Traffic signals server is again according to the phase difference to existing association Control program is adjusted to be modified.

Step 403, the revised Coordinated Control Scheme is sent to the micro process by the traffic signal controlling machine Device controls the traffic signals at corresponding crossing so that the microprocessor is according to the revised Coordinated Control Scheme.

After traffic signal controlling machine receives revised Coordinated Control Scheme, first determine that each Coordinated Control Scheme is corresponding Crossing is accessed, then the Coordinated Control Scheme at each crossing is assigned in corresponding output lamp group, executes revised coordination control Scheme processed.

In method provided by the embodiments of the present application, traffic signal controlling machine is by generating the independent road in each access crossing Mouth parameter list to determine the independent Coordinated Control Scheme in each access crossing, rather than determines traffic on the basis of single crossing The control program of signal;Also, because there are independent crossing parameter list and control program in each access crossing, work as traffic After the crossing parameter list at each access crossing and Coordinated Control Scheme are sent to traffic signals server by signal controlling machine, traffic Signal server can identify each access crossing, and coordinated control side is all corrected as independent crossing in each access crossing Case, so as to avoid the traffic signals for controlling all crossings on the basis of a crossing, the traffic that can be improved traffic intersection is logical Line efficiency.
