Research on optimal signal timing plan of the intersections with bus-only approach

本文研究设置公交专用进口道的城市交叉口信号配时,综合考虑社会车辆的运行,实现信号配时的公交优先与人均延误最小化。本文运用延误三角形及其相关理论建立延误模型,推导出人均延误函数,为公交优先单点定时控制提供了优化算法。同时本文利用VisualC仿真模型与改进算法对城市具体交叉口信号最佳周期及有效绿灯时间进行优化设计。

For intersections with bus-only approach considering social cars＇ moving the paper realizes the goal of bus priority and minimizing the average delay per person by the signal timing adjustment. The paper puts forward an optimization algorithm by applying delay triangle setting delay model and deducing the function of average delay per person on the hypothesis of car＇s uniform arrival. The paper calculates the best circle and effective green time of a specific intersection by using Visual C software and improved algorithm.
