摘要
用D-Q模型对单交叉口的车队形成、消散进行了描述,D(discharging)代表车队的消散过程、Q(queuing)代表车队的形成过程.在交通信号控制中,设计了一种以车队总延误时间为优化目标的实时的onestep控制算法.编制交通仿真系统平台,对该方法的控制效果与定时控制进行了模拟比较,仿真试验的结果说明该方法的控制效果明显优于传统的控制方式.
This paper describes the discharging-queueing of vehicle platoon using a novel D-Q model in the single intersection. D represents discharging of vehicle platoon, and Q represents queueing of vehicle platoon. It designs a real-time control algorithm called onestep in the processing of traffic signal control. The optimization index aims at the vehicle platoons total delay time. After programming the traffic simulation system, this paper compares the control effect of this new approach with fixed-time control algorithm. The simulation result illustrates that the effect of the new approach is obviously better than that of traditional algorithm.
