基于盈利最大的公交车发车次数优化模型

Optimization model of bus departure frequency based on maximum profit

随着城市的不断扩大,中小型城市的交通堵塞问题愈加严重.为了缓解交通拥堵,提高公交车的调度水平,文章首先对我国公交车调度的现状及盈利的因素进行了分析,然后建立了基于盈利最大的公交车发车次数优化模型.通过四组仿真实验的结果表明,在盈利最大的目标下,站点的数量与最低满载率均会影响公交车的发车次数,其中站点的数量对公交车的发车次数影响较小,而最低满载率对公交车的发车次数影响较大,且最低满载率越小公交车的发车次数则越多.

With the continuous expansion of the city,traffic jams in small and medium-sized cities are becoming more and more serious.In order to alleviate traffic congestion and improve the level of bus dispatching,this paper first analyzes the current situation of bus dispatching in China and the factors of profit,and then establishes the optimization model of bus departure frequency based on the maximum profit.The result s of four groups of simulation experiments show that under the goal of maximum profit,the number of stops and the minimum load ratio will affect the departure frequency of buses,among which the number of stops has less impact on the departure times of buses,while the minimum load ratio has a greater impact on the departure times of buses,and the smaller the minimum load factor is,the more frequent the bus departs.
