Study On The Coordination Control And Key Technology Of Arterial Road Based On RFID

In urban traffic, the main road is often under the maximum traffic load. Whether the main road is unobstructed plays a key role in easing traffic congestion. The intersection signal control theory points out that coordinate and optimize signal between intersections, and try to make the vehicle in the intersection parking lights through the intersection, forming a "green wave" on the road, can greatly improve the traffic jam phenomenon. If the real-time vehicle data is read on the road according to the RFID, the timing scheme of each intersection is determined, optimize the signal between the intersections reasonably. It is sure to improve the utilization rate of the green light to increase the capacity of the road, so as to slow down the congestion of the urban road traffic system.In this thesis, using RFID induction type arterial road coordinate control of continuous intersection, put forward the vehicle electronic tag and read-write device and intersection traffic control machines and other equipment linkage system establish induction trunk road coordination control system. The main road intersection maintains the same phase difference, the secondary road realizes induction control. The main road realizes green wave control, the secondary road light time can be effective used. Then optimize the current induction control strategy based on the coil. The traditional induction control whether to grant extension is determined by measured time interval of vehicle section. The improved induction signal control strategy based on the vehicle density is used as the green light to extend the judgment. Finally, through the VISSIM software simulation, the simulation results show that the efficiency of inductive control coordinated control of RFID is better than that of control and timing coordination based on induction coil based on coordinated control. The control method reduces the vehicle delay and increases the utilization rate of the green light. The study provides a theoretical basis for the future urban traffic control protocol control.
