METHOD FOR PROVIDING OPTIMAL ROUTE DYNAMICALLY BASED UPON DSRC IN TRAFFIC SYNTHESIS MANAGEMENT SYSTEM

摘要

PURPOSE: A method for providing a dynamic optimum path information in an integrate traffic control system based on a DSRC(Dedicated Short Range Communication) is provided, which provides an optimum path information to vehicles on a road in real time by collecting and processing road traffic condition data based on the DRSC network. CONSTITUTION: An OBU(On Board Unit)(21) transfers its own ID and additional information to a road side base station(22) by communicating with the road side base station, after the road side base station entered into a cell on a service. The road side base station transmits a passing vehicle information to a local center(23) according to a communication protocol determined in real time. The local center calculates traffic condition information of a territorial jurisdiction, being based on data collected from the road side base stations of the territorial jurisdiction and transmits a related information to a central center(24). The central center updates the traffic condition information of the whole road network by assembling traffic condition information from the local centers, and transfers the updated information to the local centers.
