Design And Implementation Of City Transportation Planning System

With the development of our country, people are not satisfied of basic necessities of everyday,but want to get spiritual satisfaction. So more and more people like to travel. The overseas tourism is growing rapidly in recent years. The tour is very troublesome thing. You need to consider a lot of trouble of things. Especially in a foreign country, the traffic has always been a very difficult issue in a strange city. How to get the way to the interest? What is the most convenient way to the interest? In order to solve common problems of the majority of travel enthusiast, so the thesis achieves the transit planning system. This system can solve the trouble to travel, make the travel more comfortable.The implementation of the transit planning system is based on the development process of software engineering. Completing system is divided into four steps: requirement analysis, conceptional design, detailed design, system testing. Firstly, according to the user demand for transport, identifies the main functions of system, including the map operation, information inquiry and background data management. This system is essentially a Web GIS system, which is based on B/S three-tier architecture. The system is completed by.net technology. The system uses the MVC, the database uses the SQL. The system is consistent with two types of data, bus line and POI data. There are two sources of data, including cooperation API and Web Crawl. Web crawling framework is mainly based on Scrapy. Map module uses the image pyramid theory.By using title map to complete the module. The core functionality of the system is the transit planning inquiries. By using the A Star algorithm to achieve this function. And for the lack of A Star algorithm, the thesis has made the optimization of the algorithm. Routing efficiency and quality have been improved by the optimization. This thesis has conducted a complete detailed design for each functional module. Through the analysis of related classes and functions, to complete the design and implementation of each functional modules.After the functional test of each module, the transit planning system has reached the design target. This system can provide services of city to the users who likes travel.
