The information that electronic license plate can provide is very detailed, and, in implementation procedure of the present invention, in order to reduce complexity, can only consider partial information wherein, for example, when carrying out traffic dispersion, can only consider sign and the vehicle of vehicle; And, in the key area of carrying out illegal vehicle and intercepting, can further consider the information such as color, producer, affiliated people of vehicle.
In the situation that there are a plurality of receivers in the range of receiving of teleseme, in the information of vehicles that teleseme can report according to a plurality of receivers, the vehicle information of vehicle is determined the vehicle size of driving vehicle, and conclude the vehicle fleet size (flow) on speed, travel direction and each travel direction of determining driving vehicle according to the identification information of vehicle, and further determine roadway occupancy (roadway occupancy can be determined according to the quantity of driving vehicle on all directions), thereby realized the function that vehicles identifications detection, travel direction induction detect, block up and detect.Because the vehicle in reality is comparatively complicated, the present invention can only carry out comparatively fuzzy differentiation to vehicle when determining vehicle,, vehicle is divided into large-scale, medium-sized and small-sized, like this, when carrying out traffic administration, thereby the result that the size that not only can consider the vehicle volume makes traffic administration optimize is more reasonable, and can save the processing resource, the problem of avoiding a large amount of judgements to cause handling property to reduce, reduce processing delay.
Usually, receiver can be arranged on the place, crossing of road, and, for crossroad, can be arranged on the appropriate location in four direction highway section, for example, can be arranged on the walkway on the middle safety island in road or trackside limit, as shown in Figure 2, each receiver in receiver 1 to 4 can be positioned at the distance position (can be adjusted this value according to the different situations in highway section) of 80 to 120 meters of the stop lines of travel direction separately, receive the car nationality information in 30-50 rice scope, the adjustment of signal range of receiving mainly be take and is not interfered with each other as principle.Teleseme can be arranged on the C place, position in Fig. 2, receives this four information of vehicles that receiver reports.
As shown in Figure 3, be located at four limits, crossing: receiver 1 (south, crossing), receiver 2 (east, crossing), receiver 3 (north, crossing), receiver 4 (west, crossing).Receiver 1 is craspedodrome toward receiver 3 directions; Receiver 2 is toward receiver 4 directions for keeping straight on (by entering crossing to leaving crossing), and receiver 1 is to turn right toward receiver 2 directions; Receiver 1 is turn left (by entering crossing to leaving crossing) toward receiver 4 directions, like this, the sign separately and at which two receiver receive the travel direction that just can judge vehicle and can conclude number and the ratio that obtains vehicle on each travel direction according to same vehicle based on each receiver, according to the poor speed of a motor vehicle and the roadway occupancy that can know this car of time of reception.Receiver is only done the transmitting-receiving information of vehicles of unit interval, and can repeat same vehicle information 6 times, but time of reception is sequential, if any surpassing, allows to cover a last time point.On information of vehicles, give the correct time carrying out, four receivers can report in turn.
And, teleseme can be according to the parameter of the speed of the vehicle travelled and travel direction (can further combined with quantity and the roadway occupancy of driving vehicle on individual direction) the on-site traffic signals of conditioning signal machine, mainly can regulate the Cycle Length of traffic signals and split etc., thereby realize traffic administration.For example, parameter adjustment can drive the light on and off time of the signal lamp of traffic signals to carry out by adjustment, thereby reaches the purpose that self-adaptation is regulated.
In addition, disposal system also can be for concluding the speed of definite driving vehicle according to teleseme, travel direction, the vehicle size, vehicle fleet size on roadway occupancy and each travel direction is sent to teleseme by the traffic administration instruction, the traffic administration that disposal system is sent can be used to indicate the split that teleseme is adjusted the cycle of the on-site traffic signals of teleseme and/or adjusted traffic signals, teleseme (is for example modified afterwards to the parameter of traffic signals in response to the traffic administration instruction, can make the light on and off time of signal lamp occur), just can reach the purpose of traffic optimization management.
And, quantity at teleseme is a plurality of, and close together (each other, traffic between the teleseme site easily each other the impact) situation under, disposal system can also further be considered the on-site traveling state of vehicle of these telesemes, determine that the ideal time between the on-site traffic signals of these telesemes is poor, and structure supervisory instruction indication at least one teleseme is wherein adjusted the zero-time in on-site traffic signals cycle, make the on-site traffic signals of a plurality of telesemes after adjustment meet the desirable mistiming, wherein, zero-time can be concluded by disposal system the speed of the on-site driving vehicle of a plurality of telesemes of determining according to receiver, travel direction, the vehicle size, vehicle fleet size on roadway occupancy and each travel direction is determined.After in disposal system, supervisory instruction being handed down to the teleseme execution, teleseme can continue to be adjusted according to the actual conditions at crossing, carry out real-time optimization on the basis of the basic scheme that each cycle Dou Zai center issues, arrive situation according to each cycle vehicle, realize the optimization of traffic signals in each cycle.
Concrete adjustment strategy can be selected flexibly according to the real road situation, and different traffic intensities is adopted to different control models, and for example, at traffic intensity, fixed cycle control or the control of blocking up are implemented in large zone, take the maximum traffic capacity as target; Adopt and coordinate control model in medium traffic intensity, take minimum delay as optimization aim; The situation that traffic intensity is less adopts the single-point adaptive control, take minimum stop frequency as optimization aim.
For example, suppose to determine that according to the information of vehicles of obtaining the vehicle on current road comprises motorbus, ambulance, special vehicle, can report disposal system (traffic control center) to obtain approval according to the set model of teleseme kernel, adjust the phase bit timing by these vehicle priority passes.
In actual applications, when receiver receives information of vehicles, teleseme from electronic license plate and receives information of vehicles that receiver reports and disposal system and receive the information of vehicles that teleseme reports, can adopt the mode of request-response, the mode initiatively sent etc., the present invention is not limited to this.
