针对城市道路中路边式与港湾式公交停靠站,由于公交车辆的停靠,对路段相邻车道通行能力将产生一定的影响,结合交通流理论和排队论的相关成果,分别从定性分析与定量计算两方面进行研究。以公交进出停靠站对相邻车道的影响时间为基础,建立了公交影响时间模型,进而推导出路边式、港湾式无溢出、港湾式有溢出三种情况对相邻车道通行能力模型,并通过仿真对模型进行检验。在此基础上,对模型结果、仿真结果在不同公交流量与社会流量条件下进行模型结果分析,给出路边式与港湾式公交停靠站的设置条件。
Directed at roadside and harbor-style bus stops on urban roads, this paper makes qualitative and quantitative analysis of the effects of the stopped buses on the capacity of neighboring lanes by combining the related results of traffic flow theory with queuing theory. Based on the effect time of bus stop on the capacity of neighboring lanes, the effect time model of bus station is established, from which three capacity models of neighboring lanes of roadside and harbor-style bus stops, where the buses are overflowed and unoverflowed, are derived and tested with simulation method. Then under the conditions of different arrival rates of buses and community vehicles, the results of model and simulation were analyzed, and the setting conditions of bus stops were finally given.
