Design And Implementation Of Mobile Traffic Information Dissemination System Based On Android Operating System

ABSTRACT:Intelligent transportation system is an integrated transportation management and control system, which effectively integrates advanced sensor technology, communications technology, data processing, network technology, automation technology, information dissemination technology, etc., and use these technologies in the whole field of traffic management to establish the kind of real-time, accurate and efficient integrated transportation management and control system.I consider ITS as my research direction during the period of my master's internship, and I have made some useful attempts in the design and implementation of the smart phone traffic information systems, and achieved some results."Mobile Traffic Information Dissemination System" is developed in order to meet the needs of a 3G or even 4G network, and this system can timely inform people the various traffic information in Beijing via smart phone terminals, so as to facilitate capital citizens'travel.The main work of this paper is to complete the needs analysis, outline design, detailed design, coding, testing and release work of "Mobile Traffic Information Dissemination System". The innovation points of this paper are listed as follows:1 "Mobile Traffic Information Dissemination System" can release traffic information in Beijing by graphic, text and voice, and it also has the search, path planning, GPS tracking, RSS reader, navigation, chatting, gesture recognition, file uploading, local and network music player functions. This system is so powerful that it will not fall behind in the current domestic and international phone traffic information systems.2 The pattern of this system is rarely seen in the current domestic and international phone traffic information systems and it is quite advanced. This system uses Google map to display the map on Android operating system, and it can generate the corresponding icons, which can be refreshed in several minutes according to the data sent by the server, and if a user clicks some icon, it will show the details of the information of the road and broadcast the information to the user.3 The refreshing of the icons on the map has realized the Ajax results. As of May 2010, in addition to Google and myself, I have never found anyone on the internet had realized the Ajax results of the refreshing of the icons in a Google Map, using Android operating system.
