混合车流下单车道道路通行能力分析

以跟驰理论为基础,通过对由大、小两种车型构成的混合车流不同跟驰序列、不同组合概率的研究,得出了跟驰车头时距单车道路段多车型混合车流通行能力模型。研究表明,单车道路段多车型混合车流通行能力不仅与反应时间、车辆长度、车辆速度、制动性能有关,还与混合车流的车辆组成状况及跟驰序列有关,最后分析了各影响参数之间的关系。

Cycling Trails Traffic Capacity Research of Mixed Traffic

Based on linear vehicle-following theory,different linear vehicle-following sequence and combination probability of mixed traffic flow,which was made up of heavy and light vehicles,was studied,and a capacity model of this traffic flow on sections was established using vehicle-following time headway.Research results indicate that the capacity of mixed traffic flow on sections relates not only to drivers reaction time,running velocity,vehicle length and brake characteristics,but also to combinatorial proportions and vehicle-following sequence of mixed traffic flow.Finally,the relationship between the parameters was analyzed.
