Abstract
Intelligent Transportation System (ITS) provides efficient transport system and wide range of commercial applications. Highway Electronic Toll Collection (ETC) system is one of the most important applications in ITS. Multi-lane Free Flow (MLFF) ETC system is the trend of development in the world. However, traditional communication technologies, such as infrared and RFID, cannot satisfy the requirements in MLFF ETC systems. In this thesis, we develop a WAVE/DSRC contention free polling based ETC system. The toll area is divided into reservation zone and transaction zone. Vehicles entering reservation zone request toll gate for a reserved service channel on control channel. When vehicles entering transaction zone, they use reserved service channel to pay the tolls. The multiple roadside units (RSUs) with independent service channels in toll gate use polling based contention free transaction process to toll vehicles in transaction zone. We conduct experiments by Estinet7.0, the commercial version of NCTUns, and show the reliability of tolling service in our system. We also discuss effects of variable parameter setting and give some suggestions for further system developers.
