摘要近年来，车载导航系统、手机导航系统的发展十分迅猛，人们期望导航系统可以为他们提供实时更新的路况信息，同时为他们规划行车路线，节省时间。以出租车为例的动态路径规划系统旨在完成这一目标，以实时更新的路面车流量为动态路径规划的数据，以目前在车载导航系统中应用最广泛的Dijkstra算法为路径规划算法，动态地、合理地为出租车司机挑选路径，以达到其能够在最短的时间内完成载客任务，增加客流量，获得更好收益。64526
按照程序设计的方法实现这一动态路径规划系统，使用Visual Studio 2010作为前台界面开发，以SQL Server 2008数据库开发系统作为后台数据库支持，实现了输入、输出、路径规划、数据实时刷新等功能。本系统较为稳定，界面较为友好，有着宽广的应用前景。

Title The Planning for the Dynamic Route of Taxi
Abstract
The past few years have witnessed a soaring development of vehicle navigation system and phone-based navigation system. People expect them to provide up-to-date information on traffic and save their time by planning travel route. The planning for dynamic route in the example of taxi is set to fulfill this target. By using up-to-date traffic flow as its data and Dijkstra, the most widely applied algorithm in vehicle navigation system, as its algorithm, it dynamically and reasonably picks out routes for taxi drivers so as to achieve their task on passenger volume, increase passenger flow and eventually reap better revenue.
By the method of programming, the system adopts Visual Studio 2010 as its foreground development and SQL Server 2008, a system for database development, as its background database support, which realizes the function of real-time data refresh in input, output, as well as route planning. With an user-friendly interface, the system is relatively stable therefore has a broad application prospect.
