湖北公交查询系统的设计与实现 摘 要 当今，人类社会已步入信息时代，信息化革命给所有领域带来了前所未有的变革。电脑、手机等信息工具的普及，人们获取信息变得更加完善、快捷。而随着信息技术的飞速发展，手机所蕴藏的无限商机，正在被人们逐步发掘，它不再仅仅局限于通信这一单一功能，正在朝着手提电脑甚至更完善的方向发展。由于手机价廉物美，它已成为人们获得在生活工作上等各种信息服务的最佳选择。 在我国，随着城市化的快速发展，城市公交系统也随之迅速扩大，且更加复杂化，找不到合适的乘车路线的事情经常发生。当前，复杂的公交系统使得用户往往处于迷惑的状态，给出行带来诸多不便，而手机公交查询系统的选题也正是基于该背景。本系统通过对城市公交系统的调研，提出了基于站点优先级和邻接矩阵的公交换乘算法和上下矩阵算法；以J2ME作为开发工具，将其移植到用户手机上，借助于无线互联网，能为客户随时随地提供公交信息的查询；通过测试与分析，证实了该系统的可行性及实用价值。 关键词：公交查询；站点优先级；公交换乘算法；手机；无线互联网 Design and Implementation of City-bus Information Inquiry System Based on J2ME Abstract At present, the human society marches into the information time; the information revolution has brought the unprecedented revolution for all domains. With the popularization of information tool as like Computer, handset and so on, obtaining the information is more and more perfectly and quickly. But along with the rapid development of information technology, the infinite opportunity that the handset contains is being gradually excavated by the people, it no longer merely limits to this sole function of communication, is facing to the development of portable computer or even more perfect aspect. As a result of the low-price and high-quality of the handset, it has become the best choice that the people obtain each kind of information service in life. In our country, along with urbanized fast development, city bus system also rapidly expands, and even becomes more complex. So, finding city bus route becomes more difficult. Presently, the complex city bus system causes the condition which the users often are confused, which brings many inconvenient to people, but handset city bus inquiry system is also based on this background. Firstly, the author investigates the city bus system, provides “the Algorithm based on the stand priority and the next linking matrix” and “the Algorithm based on upward and downward matrix”. Secondly, these Algorithms are transplanted to the handset by J2ME, which can provide the inquiry for city bus at any time
