摘  要
城市公共交通（简称“公交”）是与出行人员生产生活息息相关的重要基础设施。提供良好的公交服务是建设和谐社会的基本要求。以信息化为基础，促进乘客、车辆、站点设施以及交通环境等要素之间的良性互动，推动公交系统建设。鉴于中国目前的经济发展状况，中国人出行还是以公交车为主，每个城市的公交系统都比较庞大发达。因此开发一个城市公交路线查询系统就显得十分必要，也更加适应现代社会的需求。
本课题设计主要针对公交路线查询而开发设计的，采用B/S构架，利用Visual Studio.NET2003开发工具结合C#编程语言来完成了功能和界面设计，实现了公交路线的查询功能（包括按线路查询、按站点查询、按起点终点站查询，提供起点到终点的最短公交路线查询，换乘查询，也支持模糊查询。），并使用了.NET中一些web控件编写数据库连接、更新的代码，从而实现了公交路线信息的管理功能（包括对路线信息的添加、删除、修改）。
本文共分为五大章，分别是：引言、理论基础、系统需求分析、系统设计和系统实施及测试。
关键词：公交查询；站点查询；线路查询；最短路径；换乘；模糊查询；
The Design and Realization of CPT Bus Lines Query System
Abstract
City public traffic (CPT for short) is an important infrastructure closely interconnected with production and our daily life.Providing good CPT service is a basic requirement for constructing a harmonious society. Informatization as the basis, promoting the interaction between the passenger, vehicle, station infrastructure and trffic circumstance. and promoting the construction of CPT system.Whereas chinese actual economy developing complexion, people mainly take a bus going out, the CPT system of every cities is so enormous and developed.So developing a CPT bus line query system is greatly necessary, and more meeting the modern society''''s need.
In allusion to the CPT bus line query, the course design is developed and designed. It use B/S mode, and use development tool Visual Studio.NET2003 and programming language C# to completed the function and the design of interface, and realized the query of the CPT bus lines (including query by line, query by stop, query by start stop and end stop, and provide the shortest route querying from start stop to end stop, chang line query, and also support blur query.), and used some Web widgets to compile database connection and updating code, so as to realize the CPT bus lines information management(including add, delete, update the bus lines information).
The thesis has five chapters in all, they are introduction, rationale, system requirement analysis, system design, system actualizing and testing.
Key words: CPT query; stop query; bus line query; the shortest route; chang bus line; blur query;
