intelligent transport system (automotive) (ITS)
The intelligent transportation systems (ITS) approach, based on IEEE 802.11p, aims to reduce increasing road congestion and the resulting macro-economic costs of pollution and accident hazards.
ITS systems aim to provide intelligent infrastructure for vehicles and the transportation surface. The existing resources of traffic routes, parking space and energy are to be optimized, and the fleet management system of transport companies is to be improved by dynamic route selection, avoidance of empty runs and increase of traffic safety. For common applications that inform drivers with additional traffic information such as road conditions, the current traffic situation through a Local Dynamic Map( LDM) or the deployment of police and emergency services, there is the Cooperative Intelligent Transport System( C-ITS) platform, into which a wide variety of applications can be integrated.
Intelligent transport systems (ITS) operate in the frequency range between 5.855 GHz to 5.875 GHz and 5.905 GHz to 5.925 GHz. Therefore, this technology is also referred to as ITS-G5 in the ETSI standard.
The communication systems of intelligent transport systems include traffic information such as the Automobile Radio Information(ARI), digital traffic radio( TMC), freight and fleet management, car-to-car communication( C2C) and car-to-infrastructure communication ( C2I) between vehicle and radio beacons as implemented with Dedicated Short Range Communication ( DSRC) and Wireless Access for Vehicular Environment (WAVE). Other communication services in the context of an intelligent transportation system include cellular networks, satellite navigation, short-range radars, and long-range radars or XM satellite radio.
