基于HCS+的复杂交叉口交通信号配时优化

HCS+-based Optimization of Traffic Signal Timing for Complex Intersection

本文提出了一种基于HCS+的复杂交叉口信号配时优化方法,在单个交叉口信号配时优化的基础上,对相邻的几个交叉口信号配时进行协调控制,通过VISSIM交通仿真进行评价,得出了最优方案,有效提高了复杂交叉口的服务水平。

The optimization of signal timing is an important way to improve the level of service （LOS） for urban intersections. The previous studies usually take one single intersection or one road as a research object, yet this paper proposes a method based on single point HCS＋ optimization and multi-points coordinated optimization for two neighboring intersections. The evaluation results with VISSIM traffic simulation show the effectiveness of the proposed method.
