A Design Of Dynamic Vehicle Navigation System Which Based On The Wireless Networks

GIS and LBS are the hot application areas by now, and the Vehicle Navigation System was the best important application with good marketing future in this two application areas. the traditional Vehicle Navigation System was not the ability to capture the real time traffic information,this system did not manipulate the suddenly-happened traffic addition.thus,it cause this system's practicability was limited.Aim at this shortcoming of the traditional Vehicle Navigation System,this paper proffered a new design project of Vehicle Navigation System based on C/S architecture,Designed the software and hardware modules of based on this design project,create a new data mode of electronic map that can marked the real time traffic information, and then according to this data mode ,we create a new intelligentized route-search arithmetic to search the best route that evade the road with accident. Then,we developed a software to simulate the running environment of this new system use Java programming language and create a run plane for this system,all of these works proved the feasibility of this new system. At the end of this thesis ,we discussed the application foregrounds of this new system with the development of the 3G mobile communication technology.This research about new dynamic Vehicle Navigation System offset the shortcoming of traditional system, improve the efficiency and accuracy of this system ,make it become more applied, and supply a favourable base for the expending of this system's function.
