A Study on Floating Car Based Information Processing Technology


The floating car technique is one of the key technologies in ITS (intelligent transportation system)to acquire the traffic information in recent years. In this paper, firstly, the fundamental principle of floating car technique is introduced. Then, the enhanced processing procedures of floating car information system, and some important approaches including map matching, path deriving and traffic information calculating are emphasized. To review the key issues affecting information processing accuracy, such as poor GPS data precision and complex road network, a serious of enhanced approaches are presented. Finally, some experiments are given to evaluate information processing accuracy and future work is pointed out.
