A Real-time Traffic Information Collecting And Displaying System Based On Mobile Terminal

With the rapid development of China's economy,traffic congestion has increasingly become a thorny problem in urban life.At present,the urban road infrastructure of our country is nearly perfect,so it is almost impossible for the state to rebuild the urban road in a short time.Therefore,improving the utilization ratio of urban roads becomes one of the effective methods to relieve traffic pressure.Using the communication and computer technology to analyze real-time traffic can provides real-traffic information for traveler to select appropriate travel route,so it has important significance in relieving traffic pressure and helping people travel.In view of the powerful functions of mobile terminal and the popularization of application,a real-time tradfic information collection and display system based on mobile terminal is designed and implemented.The main works are as follows:Firstly,the new method of using mobile terminal to collect traffic information is proposed after analysing shortcomings of the current methods of collecting real-time traffic information,and the method of designing native mobile map APP to Web APP also raised to solve the problem of current mobile map APP cannot be used in diffent platform;Secondly,demand analysis of the server,the client and the database of system software is carried out based on the introduction of related theory and technology in system development;Thirdly,detailed design and implementation of the server,the client and the database are elaborated according to the demand analysis.The server mainly includes stroring and processing of users' information,collecting and processing of real-time traffic information,acquiring and processing of event traffic information and so on.The client mainly includes the display of real-time traffic with the support of Baidu Map,the submission and display of event traffic,personalized settings and so on.The database includes seven parts accroding to the demand analysis;Finally,simulated test is implemented,especially on the real-time traffic display and event traffic submission,and the test results are displayed;The test results show that the system achieves a good performance.The function of displaying real-time traffic and function of submiting and displaying event traffic are realised,and the desired target is achieved.
