ET-NET-an international travel/traffic information exchange network

With the continuing development of affordable mobile and fixed communications technologies the demand for real-time, accurate information on a wide variety of subjects and interests is increasing. In the transportation sector, such information demand growth can be seen in conjunction with fundamental changes in the methods of disseminating traffic and travel information to travellers. This paper describes the INTERCHANGE project´s work in developing approaches towards the electronic data interchange of traffic and travel information between traffic information centres across Europe. The work has included the drafting of pre-standards and the implementation of a pilot network, ET-NET. Both of these areas are described. INTERCHANGE is a project in the European commission-funded DRIVE II (Advanced Transport Telematics) programme.
