"Intelligent Transport Systems" (ITS) is a generic term for the integrated application of communications, control and information processing technologies to the transport system. The resulting benefits save lives, time, money, energy and the environment and stimulate economic performance.
ITS covers all modes of transport and considers all elements – the vehicles, the infrastructure, the drivers and users – all interacting together dynamically.
The main function of ITS is to provide services and information for the full spectrum of users – in particular drivers, passengers, vehicle owners and operators, but also vulnerable road users like pedestrians and cyclists – and support safe and efficient traffic management by the transport network operators. The intention is to improve the operation of the entire transport system. With ITS, road users such as motorists, freight and commercial fleet operators and public transport customers can make better judgements on their travel decisions. Factors such as traffic conditions, road maintenance or construction work may potentially impact on travel times; weather conditions will affect the road network and safety.
ITS provides better quality and diversity of information on road and traffic conditions, often in real-time. The use of ITS in Road Network Operations (RNO) also makes it possible to improve existing operating strategies and devise new ways of managing road traffic.
