基于交叉口群关联特性的主路径变向车道控制优化

Optimization design of lane changing lane based on correlation of intersection group

交叉口群的瓶颈路径是发生交通拥堵的主要路段,通过分析交叉口群关联交通特性,及各方向交通流对关键路径变向车道的影响,基于交通波理论,应用图线结合法,建立周期优化模型和相位差约束模型.以青岛西海岸经济新区江山南路交叉口群为研究对象,系统分析交通优化策略和设计方案,运用交通仿真进行效果分析,验证了适应于拥堵严重的交通网络的信号控制优化方法的合理性.

A bottleneck path intersection group is known as the main road traffic congestion, so this paper establishes the cycle model and phase difference constraint model on a careful a-nalysis of intersection group related traffic characteristics, and the direction of the traffic flow on the critical path to change lanes, traffic wave theory based on the application diagram method. The Jiangshan Road intersection on the west coast of Qingdao economic area as the research object, it analyzes the traffic optimization strategy and design scheme of analysis system with the effect of using traffic simulation, verifies the rationality of optimization method of control signal adapted to severe congestion of traffic network.
