摘要
针对城市CBD地区客流分布不均、公交资源稀缺、乘客乘车困难等问题,提出从行人角度构建公交动态查询及行人诱导系统。首先分析城市CBD地区的公交客流特征以及公交出行人群对信息的基本需求,对比当前国内几种主流公交查询软件存在的缺陷,提出了公交动态查询及行人诱导系统的总体功能与框架,并改良了影响乘车方案排序的核心算法,最后简要说明系统的一种实现方法。
Focusing problems in urban CBD（Central Business District） area like disequilibrium passenger flow,lack of public transit resources and various troubles when getting on board…etc,this paper introduces a public transit dynamic query and pedestrian guidance system from standpoint of pedestrian.The authors firstly analyze the character of public transit passenger flow,as well as the shortages of several most popular existing public transit query software in China,and then raise the basic needs and fundamental requirements.Moreover,the overall functions and structure are discussed.Also,a modified Dijkstra algorithm and dynamic programming ideas are used as the essential algorithm,by which the system can work out different recommended bus-taking suggestions during different traffic conditions.At last,a method to realize this system is revealed.
