Research and Implementation of ETC Application Based on DSRC Protocol

Highways of Dedicated Short Range Communication(DSRC) protocol-based Electronic Toll Collection(ETC) system is expensive and has poor versatility.To solve these problems,it simplifies On-board Unit(OBU) error message frame processing,designs and implements communication frame's analysis and packaging in data link layer and application layer using microcontroller,which is in line with the complex consumer transactions of ETC application process specifications.By porting program to OBU hardware system,test results show that the system is stable,and timeliness is in line with national standards.
