多线路公交站台线路容纳能力的优化

Capacity of multi-line bus station routes

在我国大部分城市,经常会出现在公交站台处有多条公交线路在此停靠,导致站台容纳能力不足,降低了道路交通通行能力以及公交运营效率.因此,当站台线路数大于站台线路容纳能力时,对多线路公交站台线路容纳能力进行研究是有必要的.本研究以公交站台通行能力为基础,引入公交平均到达率和站台平均服务率,建立排队论系统模型,对长沙市韶山南路上多线路公交站台进行现状公交站台线路容纳能力计算.当线路容纳能力不足时,以提高站台线路容量为目的,通过改变站台类型、增加站台的泊位数等方式对多线路公交站台线路容纳能力进行系统的优化研究,并找出了合理的优化方案.

In most cities of our country this phenomenon always appears that there are a number of bus lines stopping at the same bus station,causing insufficient capacity,the reduction of road traffic capacity and efficiency of bus operations.Therefore,it is necessary to study the capacity of multi-line bus station routes when the number of bus lines are larger than the station accomodating capacity.This paper is based on the capacity of bus station,bringing in the bus average arrival rate and the station average service rate,establishing the system models of Queuing Theory to calculate the accomodating capacity of lines of the multi-lines station of Shaoshan South road in Changsha.This paper aims to promote routes capacity when the station routes capacity is insufficient,systematically studies the carrying capacity of bus station lines by changing the site types and increasing the number of parking spaces etc.,and figures out the reasonable optimization program.
