摘　　要：在公交网络信息查询系统中,最优出行线路的选择是乘客普遍关注的问题。本文在分析常用的路网最短路径算法的特点及局限的基础上,以"换乘次数最少"为首要目标、"公交出行距离最短"为次要目标,且综合考虑了"步行"等因素,提出了一种适用于公交路网的最优出行路径选择算法模型。实验仿真的结果表明该模型可行、高效。In the public traffic information system, the optimal travel route choice is the question of passengers to concern. This paper presents an optimal traffic route choice model based on analyzing the characteristics and limitation of the conventional shortest path algorithm. Taking the least transfer times as primary object and shortest path distance as second object, the model of public traffic route choice is built by considering the ＂walk＂ factor. Simulation results show that this algorithm is feasible and efficient.
