针对乘客选择出行公交线路的问题,对较完善的城市公交系统进行分析研究,建立城市公交系统时间、费用及综合最优模型,给出时间、费用及综合浪费度的定义,基于Dijkstra最短路径算法思想,提出综合最优模型下的换乘策略算法,该算法为出行者提供最优公交线路的选择策略。 In view of the problem that passengers choose to travel bus line, this paper analyzes and studies the relatively perfect urban bus system, establishes the time, cost and comprehensive optimal model of urban bus system, and gives the definitions of time, cost and comprehensive waste degree. Based on the Dijkstra shortest path algorithm , This paper proposes a transfer strategy algorithm based on the integrated optimal model, which provides a choice strategy for travelers to provide optimal bus routes.
