S28, the coordinated control mode for obtaining each Signal on Highway Cross;
S29, the actual split for obtaining each intersection, all intersections are adjusted according to actual split and common period The traffic light signal length at crossing.
For above-mentioned S21 steps to S27 steps, introduce before green wave band, first count the spacing between each intersection, I.e. the length in section is Li, the average overall travel speed v of traffic flow, the signal period of each intersection and green are grown on section Degree, i.e. timing scheme (split), the phase difference for carrying out green wave band to the main line of communication by diagram method are designed.
Specifically, it is assumed that the vehicle of the traffic route scene traveling used is all electric automobile, and road For normal driving cycle.Current time, electric automobile are in main line of communication intersection A entrance, and this is set to path starting point, The default main line of communication has been passed through by i.e. expression before B, C intersection and traveling to next crossing along road 1.In order to green The phase difference of wavestrip is designed, and first counts following information:1) spacing between each intersection, the i.e. length in section are Li, 2) on section traffic flow average overall travel speed v, 3) signal period of each intersection and green length, i.e. timing scheme (split).The signal period for measuring all intersections counted is extracted, and individually compared, is picked out Numerically maximum signal period Cmax, and this value is set to the common period C of green wave band design;In plane coordinate system Transverse axis on according to LiDifferent length draw each intersection, it is vertical at it and according to corresponding coordinate points at intersection The time shaft of each intersection is drawn on direction of principal axis;According to 50% on the time shaft of first intersection (origin position) Split (i.e. traffic light duration equal length) depict the respective signal time section of traffic light, typically Initial signal is used as using green;Average overall travel speed v in section, calculating can be gone with current green time The distance sailed, and the projection using this distance as transverse axis, at origin (at the initial time of green) draw green wave band its Middle a line boundary line, with second intersection corresponding to time shaft intersect;Pass through half away from time shaft signal period water of intersection point Square upward time scale position judges which kind of coordination controlling party the traffic lights at second intersection take Formula:It is that synchronous mode coordinates control or interactive coordination control;If above-mentioned intersection point uses closer to relatively low horizontal scale Interactive mode coordinates control;If above-mentioned intersection point is coordinated to control closer to higher horizontal scale using synchronous mode.And remaining The coordinated control mode of each Signal on Highway Cross presses the design side of the coordinated control mode of second Signal on Highway Cross Formula is designed;After the completion of the coordinated control mode of all Signal on Highway Cross determines, the traffic lights letter of each intersection Number length then according to the actual each self-corresponding split counted, carries out proportionality adjustment on the basis of common period.By Step 2 is understood, when being travelled in green wave band of the vehicle between adjacent intersection with green wave band average speed, if from a certain intersection The green light initial time at crossing plays timing, and ideally then needing to travel so for a period of time can be at next intersection Just green is met, so as to continue to be travelled in green wave band;If driving into crossing within the period beyond green wave band is wide, Experience red light is had, the situation that parking waiting forms queues such as stopping occurs, the work(that can be shunted using intersection to traffic flow Can, travel speed is adjusted, can be reintegrated in a manner of amendment with certain probability in the green wave band of main line.
