Trends and Applications of Cooperative Intelligent Transport Systems (C-ITS)

Abstract

Intelligent transport system (ITS) is a controlled system which uses sophisticated technologies to increase road safety and enhance management of traffic flow as well as to support travelers of all classes, drivers, passengers and pedestrians. With the development of internet and wireless communication technologies, current studies have moved towards cooperation on the road and between transport systems, a new trend was born: the cooperative intelligent transport systems (C-ITS), these systems based on availability of the information and interaction of the vehicle with its environment and other vehicles. In this paper the C-ITS trends and their applications in transport systems are reviewed and discussed. Our work aims to present a comparative study of wireless communication technologies used in transport systems, two types of wireless communication technology are indicate: (1) Radio frequency (RF) technology like Dedicated Short-Range Communications (DSRC), Radio-frequency identification (RFID) and WIFI, (2) Optical wireless communication (OWC) based on visible light technology (VLC). Results show that the DSRC technology is more used and applied to make the cooperation between road entities. A case study of using wireless communication technology in Moroccan highways based on DSRC technology is presented.
