摘要
交通路口的信号配时大多采用只考虑机动车辆影响的F 韦伯斯特 B 柯布理论 ,不适合中国混合交通流的特点。本文考虑混合交通流环境下机动车和非机动车辆对信号配时的影响 ,对F 韦伯斯特 B 柯布信号配时公式进行改进 ,提出适合中国国情的交通路口信号配时计算公式。最后通过北京市体育馆西路路口的实测交通数据验证信号配时公式有效性 。
Conventional signal timing of traffic at intersection mainly use F.V.Webster and B.M.Cobbe's theory that only consider the influence of vehicles, it doesn't fit in with the signal timing of traffic at intersection in China.This paper consider the influence of not only vehicle but also non-vehicle traffic on signal timing,amend the F.V.Webster and B.M.Cobbe's signal timing formula and put forward the signal timing formula that fit in with the signal timing of traffic at intersection in China. At last,the simulation based on the data of Gymnasium West Road intersection verifies the effectiveness of the signal timing formula with some discussions.
