Abstract:

A large number of urban bus routes and bus stops are clustered in the central business area, which provides the mobility for the city residents but brings about traffic-related problems at the same time. For example, one of the common phenomena is that many buses are seriously delayed at the bus stop, particularly in the rush hours. The paper attempts to minimize the total delay of the buses at the same stop through analyzing the characteristics of bus routes and docking time of the buses, taking into account the temporal characteristics of the docking buses and the passengers' demand, and finally determining the optimal capacity of the bus stop. The paper proposes a new approach to reduce the redundancy of bus routes at the same stop. The paper also verifies the practicability of the model through a case study.

摘要：

数量众多的城市公交线路和公交站点密布在中心城区，在给居民提供便捷通 行的同时，也给城市交通带来了诸多难题.大量的公交车辆在同一个中间站到发，导致车 辆停靠时排队延误严重是最普遍的问题，尤其是在早晚交通高峰时段.本文从公交中间站 所服务的公交线路数和各线路车辆停靠时间特征入手，以各线路车辆在研究站点区域无 延误到发为控制目标，结合车辆停靠时间特性和乘客出行需求特点，确定公交站点的最 优通行能力，即不产生因车辆排队而造成延误的最大服务能力，并给出调整冗余线路的 优化方法，最后通过一个算例来验证模型的实用性.
