基于非等间隔的两线路公交换乘模型研究

摘要

Aiming at the unreasonable distribution of bus in time and space in the current public transportation system ,the problem of interchange between bus lines is studied .Under certain constraints ,this paper adopts the way of non-equal intervals to arrange schedules of two bus routes .The method increases the number of transfer times for two bus routes and coordinates bus arrived time in transfer site .In this paper ,the least total transfer waiting time is set as the target and the inter-route transfer model is built . The genetic algorithm is used to solve the model . Finally ,the model and the algorithm is validated by the scheduling data of two bus route in HangZhou city . The experiments prove that the proposed model can increase the transfer opportunities and reduce the passengers' transfer waiting time effectively .%针对当前公交系统存在公交车在时间和空间上分布不合理的情况,研究了公交线路间换乘问题.在约束条件下,通过采用非等间隔发车的方式安排两条线路的行车时刻表,实现增加两条线路的公交车在换乘站点的可换乘次数并协调公交车到站时间.研究以乘客的总换乘等待时间最少为目标,建立了公交线路间换乘模型,并利用遗传算法求解.最后,使用杭州的两条公交线路运营的实际数据对本换乘模型进行了检验,从而证明了本模型有效地增加了换乘机会,减少了乘客的换乘等车时间.
