Telecommunication technologies and informatics – in short „telematics“ – experience rapid progress and increasingly influence everyday life. This includes applications in transport. The use of telematics in transport aims at - providing relevant traveller and traffic information - organisation of procedures in private and public transport - improvement of safety - optimisation of routing - linking various modes - improvement of infrastructure use. The use of modern traffic management and information systems is frequently considered a most important way to guarantee mobility. In some applications such as air transport, telematics are well established and indispensable.
