This paper analyzed the normal weighted directed graph, the characteristic and topological model of urban public transportation, and thought it is difficult to describe urban public transportation net with the current data structure and the data structure does not suit to solve the query problem of transit route with the classical shortest route algorithm. The paper proposes that urban public transportation net can be described with database technology, and presents a structure of public transportation based on database. Then, a bus query algorithm is presented based on database. According to the result of an application of the algorithm, the algorithm is effective.

本文分析了常用赋权有向图和城市公交网络的特点及其拓扑模型,认为用现有的数据结构表示公交网络比较困难,不适合用经典的最短路径算法来求解公交线路查询;作者提出利用数据库技术可以简单清晰的描述公交网络,并给出了公交网络的一种数据库结构;在此基础上,给出利用数据库的公交网络查询的算法;最后,通过一个实例证实了该算法是有效的。

In the public transportation networks described by the traditional methods,there is more than one link in the same direction between two nodes.So no way can be adopted to solve the shortest path problem in public transportation networks.To solve this problem,this paper brings forward a new description of public transportation net-works,by which all classic algorithms for the shortest path problem can be applied to the public transportation gui-(dance) system.Moreover,three single-objective...

In the public transportation networks described by the traditional methods,there is more than one link in the same direction between two nodes.So no way can be adopted to solve the shortest path problem in public transportation networks.To solve this problem,this paper brings forward a new description of public transportation net-works,by which all classic algorithms for the shortest path problem can be applied to the public transportation gui-(dance) system.Moreover,three single-objective and a multi-objective public transportation guidance models based on this description are proposed to satisfy different passengers.The effectiveness of the proposed description and models are then proved,and the proposed models are finally implemented in the public networks of Guangzhou,indicating that the proposed description and models are very effective.

在采用传统的公共交通路网描述方法的公交网络中,会出现大量两节点间有多条同向边的情况,这使得无法求解公交网络中的最短路径问题.有鉴于此,文中提出了一种新的公交路网描述方法,该方法克服了以上问题,使得所有经典的最短路径算法都能够用于公交诱导系统.在此基础上设计了3个单目标和一个多目标公交诱导模型来满足不同乘客的需求,同时对文中提出的描述方法和模型的有效性进行了证明.最后,以广州市的公交线路网络为例,对所提出的公交诱导模型进行了试验,结果表明所提出的方法和模型是十分有效的.
