基于MFC/Access的交通换乘路线设计 摘 要 现如今，人们的出行方式有了更多的选择，城市公交系统作为交通运输的主体得到了迅速的发展，但是目前我国的城市公交换乘信息系统还未发展到较为先进的水平,广大的城市民从公交信息系统得到的信息不是很全面，信息量比较少,为了解决这种状况,使城市公交加速发展，更加信息化，设计一个公交换乘信息系统有较为现实的应用意义。本次设计是基于MFC/Access的公交换乘路线信息系统。首先将公交路线网抽象成一个带权图，然后根据用户提供的起始站点和目的站点，运用dijkstra算法进行有哪些信誉好的足球投注网站，为用户提供一个最优的乘车方案。本系统使用Microsoft Visual C++6.0作为开发工具，用VC++中的MFC应用程序框架来实现。这个公交换乘信息系统主要包含两个模块，分别是查询模块（按照线路、站点和两站点查询）和管理更新模块（公交线路管理和管理员账户管理），最后根据本系统在开发阶段和调试阶段出现的问题,得到了系统需要改进完善的地方,总结了设计开发本系统所得到的经验和收获。 关键词：dijkstra，路线换乘，MFC架构 Design of Transfer bus route based on Dijkstra algorithm Abstract The development of the bus passenger information system is in a level that fall behind of the city in our country. The large part of passengers can acquire few ways of the information. So its practical for us to develop citys bus passenger information system in order to resolving this problem. The design is based on the dijkstra algorithm bus transfer line query system. First, It’s need to change the bus route network into a weighted graph abstraction, Then the system searches use by the dijkstra algorithm according to the initial site and destination site which provided by user, and provides users with an optimal travel program. The system uses Microsoft Visual C++6.0 as development tool,achieves by the MFC application framework which in VC++. these functions can be divided in to two parts---search system (Including the line search、station search and between two stations search) and management update system(Including Bus line management and Administrator account management). At last according to the problems that happened in the period of using, I summed up some ways to improve the system, and some experiences that I can have from this research.
