A Dynamic Cooperative Traffic Control (DCTC) for the Reduction of Time Delay

摘要

This paper proposes a cooperative and dynamic traffic control method to reduce the time delay for all the vehicles in an isolated intersection based on the vehicle-to-infrastructure connection. The originality is shown by the following processes. Firstly, once the vehicle enters the communication zone, it sends its arrival time range to the intersection. Secondly, the control center applies Artificial Bee Colony to optimize the passing sequence with the dynamic group of the compatible trajectories under the related safety constraints. At last, each vehicle plans its speed profile to meet the optimal entrance time and speed in the intersection calculated from the passing sequence by the control center. A series of simulations are executed under the traffic volume from 100 to 500 (veh/h/l). The comparison of simulation results with other papers proves that the proposed method is very effective and all the vehicles can finish their entire trip with a near free-flow speed.
