基于mfcaccess的交通换乘路线设计-学位论文

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进展，但是目前我国的城市公交换乘信息系统还未进展到较为先进的水平,宽阔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,使城市公交加速进展，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 算法进行搜索，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（根据线路、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 AbstractThe 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 it's practical for us to develop city's 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 s...
