基于车流无缝衔接的短连线交叉口协调控制方法

Control of Coordination of Short-linked Intersections Based on the Seamless Connection

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。

Directed against the problem that short-linked intersections often over-flow, a coordination control model aiming to minimize the average vehicle delay is built based on seamless connection between traffics.The paper proposes a coordinated control model of short-linked intersections based on minimization delay with queue length constraints and seamless joint between traffics.Then,the left turn traffic queuing constraint model is established with wave theory.Finally,the results show that the average vehicle delay reduced by 38.3%,at the same time,no left turn traffic overflow after using simulation software authentication validity and applicability of the coordination strategy.
