The Research on Road Model in Real-Time Navigation System

摘要：

Vehicle Navigation System is a main part of logistics and supply chain management system.This system can reduce transportation times and get high efficiency.This paper analyzes static road model firstly,a road can be expressed by five parts: node,shape points,line,segment and path.Then a dynamic road model with real-time traffic message Intelligent Transport System implemented to get better navigating performances.Some new congestion coefficients are designed to express the real-time road situations.Based on the ITS development in our country,a real-time data acquiring method is built through gathering traffic messages from public information publishing system.
