Tan Bus Integrated Query System Design And Implementation

In recent years, with the ChangZhuTan group’s rapid economic development, Population also increased dramatically, which brought a lot of travel problems. If you increase the number of private cars, will make the traffic congestion problem is getting worse. Now often reported the city’s main line blocking twelve hours every day, even thirty-four hours. Because the block was relatively long time, it is easy to make people impatient, and very prone to conflict, so only in order to increase the number of buses without increasing traffic pressure in the case, people can travel very well have to solve the problem. The bus system is a an important manifestation of the city’s economic development, transport sectors have also made great efforts, but it also made a great challenge to the public. In order to establish a sound public transportation system, the need for additions or changes to the line, and add or modify the sites. However, the public’s memory is limited, it is impossible for all lines are well known, therefore, a good integration of Changsha, Zhuzhou and Xiangtan’s bus system is imperative.This article from the perspective of the users designed a Changzhutan bus integration system for the user’s query. After analysis the needs of the users、system development environment, key technical, general requirements analysis, system process models, data flow diagrams, overall design, in a depth analysis. Fast query system and convenient public transportation is an important feature, so for the aspect we study some algorithms. When a user queries some of the lines may not be a direct train, which requires a good transfer algorithm. In the least time, least expensive, at least transfer and so on, a good algorithm is also very important to transfer. In order to facilitate the administrator of the line, trips, site maintenance and other information, we designed a system maintenance function. In order to receive timely public users’ opinions and suggestions for the transport system, we designed a message board, users can not login, you can put your own thoughts, convenient and simple. Experiments shows that the system interface is simple and elegant, with a good performance.
