摘要
公交优先是缓解城市交通问题的一种有效方法,故提出在过饱和信号交叉口进口道处设置成锯齿形,并设置车道预信号灯。本文基于定数理论的背景和信号交叉口延误理论,在已有延误研究的基础上,对过饱和信号交叉口进口道延误进行分析,推导出相应的进口道延误公式,通过对公交优先方案实施前后的交通效益评价对比,证明该方案是有效且可行的。
Bus priority is a means to provide efficient transport services in urban areas, thus indented stops and pre-signals are proposed at approach over-saturated signal intersections.This thesis bases on fixed number theory and the theory of signal intersection delay, analyzes the approach delay of over-saturated signal intersection, and then infers corresponding approach delay formulation.Through traffic benefit analysis before and after bus priority, this measure is effective and practicable.
