摘  要
公交查詢系統是城市道路交通的重要組成部分,是城市發展的必然產物,是聯系國民生活、社會生產和流通領域的關鍵環節。我國城市公交查詢系統的發展處于一個較落后的水平,人們可以獲得信息的方式很少,為了解決這種問題,設計出基于J2EE的公交查詢系統。
本論文詳細介紹了整個系統的已實現的功能。首先，實現多種查詢功能，包括根據商廈名稱、公交車號、日常站點、和任意兩個站點查詢乘車路線。其次，采用最短路徑算法查找任意兩個站點之間的最短乘車路線。最后，提供了用戶留言的功能、用戶管理功能和后臺車次管理功能；用戶留言功能，主要是收集用戶的留言信息，可以根據用戶提供的留言信息或是提出的建議，對系統進行修改和完善；用戶管理功能，主要是刪除用戶信息和修改用戶基本信息；后臺車次管理功能主要包含添加車次和站點功能、更新車次和站點功能、刪除車次和站點功能，這樣做到系統實時更新，為用戶查詢提供更為準確的信息。

關鍵詞：J2EE；最短路徑算法；公交查詢

Design and Realization of Public Transport Inquiry System Based on J2EE
Abstract
Urban public transportation is an important part in traffic and transportation domain, and it's also the inevitable result of social economy's development in urban areas. As an important part of urban transportation system, urban public transportation system is acting a key role in human living, in social production and in transportation domain .But the inquiry system of public transportation developments in our country is in a comparatively backward level. The general passengers have less way to obtain the information. In order to solve this kind of problem, an inquiry system of public transport based on J2EE is designed.
The thesis has introduced the realized functions of entire system in detail. Firstly, the system has realized many inquiry functions. The system can search bus route by the name of business mansion, the number of public transport, ordinary bus station and two arbitrary stations. Secondly, the system uses the shortest path algorithm to find the shortest travel routes between any two stations. Finally, the system provides the functions of consumer message, the bus number managing on the backstage and the consumer managing. The function of consumer message mainly collects suggestions from consumer to modify and perfect the system functions. The function of user managing is to delete user information mainly and revises the fundamental user information. The functions of bus number managing are mainly to add, update and delete the bus number and the station on the backstage. These can enable the system have the quality of real-time updating to provide the accurate information for user.

Key words：J2EE; Shortest path algorithm; public transport inquiry
