Abstract:

The real time traffic information acquisition and distribution system based on the Mobile Internet is composed of three parts,the client software running on the smart mobile phone terminal,the  realtime traffic server on the Internet and the query client software running on the smart mobile phone terminal.The system acquires traffic information about the location,speed and direction of those in traffic using GPS,AGPS and GPS data security technology,and processes data by data mining and GIS map matching etc,and releases data using Web GIS and dynamic path planning.Urban traffic problems can be found using data offered by the MIRTTS system,on the basis of which we propose a professional solution to traffic problems,thus alleviating urban traffic congestion,saving resources and reducing motor pollution emission.

Key words: GPS data security;data mining;GIS map matching;location based service;dynamic path planning
