直行优先信号控制交叉口左转交通流延误模型

根据国际上通用的信号控制交叉口直行交通流优先通行的规则，运用无信号控制交叉口优先型交通流延误分析的Adams理论，推导出直行优先型信号控制交叉口左转机动车交通流延误模型．其成果既完善了现有的延误计算理论，又可为设；置信号相位提供理论依据，同时还可用于分析我国信号控制交叉口实际运行状态所存在的问题．

Traffic Delay Model of Left-turn Flow on Signalized Intersection with Straight-going Priority

This paper demonstrates the traffic delay model of left - turn flow on the signalized intersection with staight - going priority. Based on the cmmon rule of staight - going Priority in signalized intersection, this model is developed with the Adams's theory about traffic delay analsis of priority intersection. Its result not only consummaes the theory of calculating delay, but also provides the theoretical basis for seting up signal phases. It may also be used to analyze the existing problems in the practical operating process on signalized intersection in China.
