摘要:

为了解决人们出行公交路径选择问题,分析了公交网络的特点,对最短路径常用算法进行比较,提出一种基于双向搜索的公交网络路径选择算法。为了选择最优路径,综合考虑出行时间、出行费用和换乘次数等因素,给出一个综合评价指数模型,并用算例对算法和模型的可行性进行验证。基于数据库理论,算法用数据库表示公交网络,用数据库查询技术实现最优乘车路经选择,易于实现,执行效率较高。

关键词: 公交网络, 最短路径, 最优路径, 广度优化搜索, 综合评价指数模型

Abstract:

In order to solve the public transportation route choice problem, the feature of public transportation network,compares algorithms of shortest route,  and selection algorithm of public transportation network routes is analyzed based on two-way search. In order to select optimum route, thinking about the factors which are time of transfers, cost of running and times of transfers, a compound evaluation index model is obtained.An example is given to valldate possibility of the algorithm and the model.Based on the database theory, the algorithm expresses the public transportation network with the database, realizes the most superior riding pass choice with the database inquiry technology, it is easy to realize, and to be efficient.

Key words: public transportation network, shortest route, optimum route, breadth first search, compound evaluation index model
