Potentiale, Wirkungen und ökonomische Bewertung von hochwertigen Verkehrsinformationsdiensten

This paper analyzes the high-end range of traffic information systems for individual motorized traffic and for public transport. High value-added traffic services are characterized by dynamic, personalized information, including suggestions for alternative routing; they are supplied on a commercial basis, mainly by private enterprises. Based on a qualitative forecast of the diffusion of high value-added traffic information systems, we estimate their potential impact on the transport system as a whole, as well as on the environment. The approach also considers the strategies of the key actors (mainly enterprises) at each level of the value-added chain: Primary data collection and treatment, distribution of information services, data transfer, and the reception of information via specialized devices. The study concludes that high value-added traffic information systems will be much more widely diffused in the future, both in public transport and in individual motorized traffic. Traffic information services will also lead to a more efficient use of infrastructure. However, as regards economic policy, there seems to be no need for state intervention to remedy market failure. -- Telematics ; Traffic Information Services ; Market Failure ; Market Development ; Verkehrstelematik ; Verkehrsinformationsdienste ; Marktversagen ; Marktentwicklung
