Design of electronic toll collection system based on global positioning system technique

Currently, most electronic toll collection (ETC) systems around the world are implemented by DSRC (dedicated short range communication) technology. However Global Positioning System technique is applied to ETC to replace DSRC technique in recent years. It is an innovative technology for expressway network electronic toll collection solution, which is totally different scheme comparing to traditional DSRC-based technology. In this paper, the frame composing and working flow of the system are described, the design of GPS-based ETC system are discussed detailedly, and the advantages and disadvantages of the system are discussed at last.
