针对短连线交叉口经常出现排队溢出的问题,以交叉口的车均延误最小为优化目标,建立基于车流无缝衔接的短连线交叉口协调控制模型,运用波动理论建立排队约束模型,加入左转车流排队长度约束。最后,采用交通控制仿真软件验证本文提出的协调策略的有效性和适用性。仿真结果表明:采用基于车流无缝衔接的协调控制方法后,车均延误降低了38.3%,且无左转排队溢出。
In order to solve the problem of queuing and overflowing at short-connected intersections, aiming to minimize the delay of vehicles at intersections, a coordinated control model of short-track intersections based on seamless convergence of traffic flow is established. The queuing constraint model is established by using wave theory. Turn left traffic queue length constraints. Finally, traffic control simulation software is used to verify the validity and applicability of the coordination strategy proposed in this paper. The simulation results show that with the coordinated control method based on the seamless convergence of traffic flow, the average delay of the vehicle is reduced by 38.3% and there is no left-turn queue overflow.
