Abstract

Floating vehicle equipped floating vehicle technology has been widely used to collect urban and inter-urban road network traffic data for network evaluation, traffic management and dynamic road guidance purposes. It has become one of the major technologies of Intelligent Transport Systems (ITS). Most of the commonly used floating vehicle devices receive floating vehicle data in a frequency of 1 Hz. To collect real time traffic data of the road network for the above application, floating vehicle data from floating vehicles has to be transmitted from vehicles to a traffic data management centre in short time intervals. With the increase in the numbers of floating vehicles, the cost on communication increases dramatically. This is often one of the major barriers limiting the application of floating vehicle technologies for real time traffic route guidance and many other applications. This paper proposes a floating vehicle - floating vehicle data transmission strategy, which can significantly reduce the data transmission cost with satisfied accuracy for real time traffic management and dynamic road guidance purposes.
