摘　　要：为了进行直线式公交站选型优化,根据南京市某公交站台的调查数据,考虑交通负荷、公交车占用站台时间及停靠频率因素,比较虚拟港湾式公交站与普通直线式公交站对交通流的影响,建立了沿机非分隔带虚拟港湾公交站的车流速度模型.该模型可计算车延误,并结合通行能力进行公交站选型.研究表明,单车道路段设置虚拟港湾式公交站有利;两车道路段根据交通负荷等参数确定公交站选型;公交车平均停靠时间不超过1 m in时,3车道路段设置普通直线式公交站有利.For type selection of beeline bus stop, the influences of virtual-bay bus stop （i. e. , a bus stop with reverse harbor on line） and common beeline bus stop on traffic flow was compared according to the investigation data from a bus stop in Nanjing in terms of the influential factors such as traffic load, bus dwell time, and bus arrival rate at the stop. Then, an overall traffic flow speed model was established under the influence of a virtual-bay bus stop along side divider. This model can be used to calculate the delay of traffic at the bus stop, which, together with the traffic capacity, can be used to optimize the selection of beeline bus stop types. Calculation results based on this model show that for single lane roads, virtual-bay bus stop works better; for two-lane roads, type selection needs to be made according to multiple traffic factors such as traffic load; and for three-lane roads, given the average dwell time of buses shorter than 1 min, common beeline stop wins.
