城市公交查询系统 临汾职业技术学院09届计算机应用技术专业毕业论文 城市公交查询系统 摘 要 我国城市公交乘客信息系统的发展处于一个较落后的水平，广大乘客可以获得信息的方式很少。为了解决这种问题，需要加快发展城市公交信息化，大力发展我国的城市公交乘客信息系统。设计一个城市公交查询系统是具有一定实际应用意义的。在此背景下，开发了这个应用程序---城市公交查询系统。本次设计，从城市公交查询系统建立的必要性出发，首先考虑了公交运营的实际情况和不同公交乘客的实际要求，分析了此系统应该具有的功能;其次对系统的主要功能模块进行了详细地描述，在对公交乘客出行心理特征进行分析的基础上，考虑了乘客选择公交线路决策的因素，探讨了以换乘次数最少为目标的公交查询系统的实现方案。本系统选用Qt4作为开发工具，SQLite作为后台数据库，开发城市公交查询系统，实现两个模块---查询模块(包括基本查询和高级查询)和管理更新模块(包括公交站点管理和公交线路管理)的基本功能。最后结合系统开发阶段和调试阶段发现的问题，提出了系统需要完善的地方，总结了开发此系统所取得的经验。 关键词 公交;Qt;SQLite - I - 临汾职业技术学院09届计算机应用技术专业毕业论文 Urban Public Transport Query System Abstract Chinas urban public transport passenger information system development in a comparatively backward, the majority of passengers, the way information is rarely available. To solve this problem and needs to accelerate the development of urban public transport information, to develop Chinas urban public transport passenger information system. Design a city bus check system has some practical meaning. In this context, the development of this application --- the city transit system.This design, from the city to establish the need for public transport query system, we firstly consider the actual situation of the bus operators and bus passengers in different practical requirements, should have analyzed the function of this system; Second, the systems main function modules in detail described in the psychological characteristics of the bus passengers travel on the basis of the analysis, taking into account bus routes and passengers in decision-making factors, discussed in order to transfer the least number of queries for public transit system was implemented. Qt4 use the system as a development tool, SQLite as a background database, development of urban public transport query system, to achieve the two modules --- Query Module (including the basic query and advanced query) and management update module (including site management and bus lines bus management) the basic functions. Finally, system development a
