Abstract: In order to keep the high efficient access rate of the green wave and coordinate the reasonable traffic flows of the main road and the branch road,a method of main and branch road adaptive coordinate control on timed Petri net modeling was presented.According to the traffic flows of the main road,this method can change the phase time automatically.According to the phase time and the traffic flows of the main road,this method can also change the phase time of the branch road automatically.By analyzing this case,this method can achieve the adaptive coordinate control of the main road and the branch road effectively.Then,it makes the number of vehicles in the branch road passing the intersection as large as possible,and it can guarantee the smooth flow of the green wave band.Thus the method can improve the access efficiency of the intersections.

Key words: Coordinate control,Green wave band,Timed Petri net,Adaptive control
