公交停靠站区域长度优化研究

Study on Length Optimization of Bus Stop Zone

基于马尔可夫,研究建立了公交停靠站平均排队长度模型。在高峰时段,车辆到达满足泊松分布,基于马尔可夫的停靠站区域长度模型,确定停靠站的区域长度。运用VISSIM仿真软件,对典型的公交停靠站进行仿真,验证马尔可夫模型在确定停靠站区域长度的可行性及合理性。然后,对典型的公交停靠站进行改造方案的研究,通过平均排队长度、最大排队长度以及公交车辆的延误等统计结果,确定合理的改造方案,优化现有的停靠站区域长度。

Based on Markov chain,the paper establishes average queue length model of bus stop.By the model,the length of bus stop zones is determined.By VISSIM,the paper researches on a typical bus stop simulation and certificates Markov model in order to determine the feasibility and reasonableness of zone length.For the typical bus stop,paper studies rehabilitation programs on the average queue length,maximum queue length and delays.Based statistical results,the paper determines a reasonable rehabilitation programs and gives an optimization design instances.
