摘要： 为实现干线协调,提高运行效率,基于线控系统中车流以波的形式到达的基本认知,分析了相邻交叉口车辆排队的时空特性,指出了干线协调的内在机理是当车流到达队尾位置时排队完全消散。然后针对排队的集结与消散建立了基于交通波的交叉口相位差模型。并鉴于干线各交叉口间的关联性以及交通需求与供给关系,提出了对干线控制参数的优化策略。最后选取青岛市漓江路沿线交叉口进行案例分析,验证相位差模型以及周期、相位相序、绿信比等优化策略的可行性与实用性,结果表明该控制方法对车辆旅行时间、停车次数的优化效果显著。

Abstract: To achieve arterial coordination and improve operational efficiency, the space-time characteristics of vehicle queuing at adjacent intersections were analyzed based on the consideration of vehicle arriving in a general state of traffic-wave in coordinated signal control system. Then, the internal mechanism of arterial coordination was considered that the queue was dissipated as vehicle reached the end of the queue. According to the aggregation and dispersion of queue, intersection offset model based on traffic-wave theory was established. Giving the intersections relevance and the relationship between demand and supply, the optimization strategy for arterial control parameter was proposed. Intersections on Lijinag Road, Qingdao City, were used as example to verify the feasibility and practicability of the offset model and optimization strategy for cycle, signal phase and split. The results indicate that the control method has remarkable effect on vehicle travel time and vehicle stopping times.

Key words: engineering of communication and transportation system, traffic-wave theory, offset, arterial coordination, queue
