Bus Stop Capacity Research

As the traditional transit mode, bus is the main part of transport for the advantage of lest investment, flexible operation and large coverage of network. As the nodes of bus transit, bus stop is one of the most important infrastructure in the transit network, also the bottleneck of traffic. Therefore, accurate analysis of bus stop capacity is important for rational design of bus stop to ease traffic pressure.This paper analyses the stop process of a bus and gives the characteristics of the pull in process, parking process and outbound process, later makes a detailed analysis of how every factor affects bus stop capacity from four aspects, including bus, bus stop, road traffic and personal. Then based on the parking process and the influencing factors, arrival distribution sub-model and dwell time sub-model are established firstly. Through the analysis of the interaction between the different buses, focus on developing the out time sub-model, based on the volatility of the bus arrival and dwell time. Then in time sub-model is established based on the dwell time and out time sub-models. And then combined with the definition of capacity, linear bus stop capacity model and harbor-shaped bus stop capacity model are established.It makes an example to calculate the capacity of linear bus stop and harbor-shaped bus stop. Finally,it uses VISSIM to simulate and calibrate the simulation mode, and gets the capacity of three berths stops, then analyzes and compares the results of method with the theoretical value.
