Abstract
Intelligent Transportation System (ITS) is to utilize the sensing, networking and information technologies for transport applications such as road and vehicles. In ITS, various sensors and networks play a vital role in the capturing and transmitting of transportation information. Especially, wireless networks' spectrum resource and reliability are important factors in this system. In this paper, we firstly give a brief description of the techniques adopted by the Intelligent Transportation System, and we then study an heterogeneous sensing and networking platform for the ITS traffic monitoring applications. A case study on video camera based traffic monitoring is given and the adoption of Low-Density Parity-Check (LDPC) coding is proved to support reliable communication.
