The research of parking guidance and information system based on dedicated short range communication

Parking guidance and information system (PGIS) is a part of intelligent transportation system (ITS). As a new short-range wireless transmission technology. Dedicated short-range communication (DSRC) is a rock-bottom communication technique of ITS, which realizes the communication between roads and vehicles. In this paper, the DSRC system was introduced. The architecture of PGIS based on DSRC was built up. The information provided by PGIS, as well as its functions and characteristics, was discussed. The key problems in implementing PGIS were put forward.
