中文摘要
      为解决公交站点因需求集中而出现的排队问题,以排队原因为切入点,通过分析,揭示了站点供给与公交需求之间的矛盾关系是造成公交排队的根本原因。建立了一种防止公交排队溢出的交叉口控制方法。首先,建立公交延误模型和站点停靠时间模型。然后,基于这两种模型和信号方案,建立了公交溢出判断模型和公交准点判断模型。最后,将这些模型应用到控制方案中,提出了一种新的公交防溢出方法,实现交叉口公交防溢出功能和公交优先控制。利用VISSIM软件对该控制方法进行了仿真分析,结果表明该控制方法能够有效防止公交排队溢出进入交叉口。
英文摘要
      To address the issue of queue spillbacks at bus stops due to high traffic volumes, this study focused on the queue formation, analyzed the relationship between the capacity and the traffic demand at bus stops, and proposed an intersection control approach to avoid queue spillbacks at bus stops. Firstly, a bus delay model and a dwelling time model were built. Then, the judgement models of queue spillbacks and on-schedule buses were built based on the above two models. Finally, these models were applied to a traffic control scheme and an approach to avoiding queue spillbacks at bus stops was proposed, which could also provide bus priority control. VISSIM software was used for simulation validation and the results demonstrated that the proposed control approach was able to prevent queue spillbacks at bus stops.
