Sponsored by the Niedersächsische Technische Hochschule (NTH), the research project PLANETS (Planen und Entscheiden in Netzwerken autonomer Akteure im Verkehr) adresses the development and evaluation of new innovative approaches for a cooperative management of traffic in cities based on Car-to-X communication. The interdisciplinary project consortium consists of four partners at three NTH locations: In PLANETS, the IKT cooperates with the Department of Transport and Urban Engineering and the Institute for Business Information Systems (Department of Decision Support) at the Technical University of Braunschweig and the Department of Informatics (Research Group Mobile and Enterprise Computing) at the Technical University of Clausthal.
Wireless networks between vehicles as well as between vehicles and infrastructure (Car-to-X-communication) are currently adressed in the context of worldwide activities in research, development and standardisation. This technology of the future can be applied in various environments. Besides services of information and entertainment (e.g. dynamic navigation, mobile access to the Internet), applications enhancing the efficiency of traffic (e.g. to avoid traffics jams, enhanced route guidance, etc.) and increasing traffic safety (road hazard warnings, signal violation warning, etc.) are of particular interest.
The Car-to-X system electronically extends the driver's horizon and enables entirely new safety functions. Traffic participants shall be warned of not yet visible but critical dangerous spots (e.g. ends of traffic jams). Applications to enhance the efficiency of traffic like e.g. intelligent traffic lights are possible. Car-to-X communications form a well suited basis for decentralized active safety applications and therefore will reduce accidents and their severity. Currently, there is a lack of methods to achieve cooperation between traffic participants and collective management of traffic. Furthermore, we need testing environments, in which prototypical functions of assistance can be tested realistically and from which valid valuations can be deduced. The technical realisation is based on the protocol family IEEE 802.11 (wireless LAN). Nevertheless, there is a lack of research, in which the real value of Car-to-X communication is proved. Such researches are essential in achieving a successful market launch.
One of the aims of the research project PLANETS is the development of efficient functions in assistance management and traffic management based on Car-to-X-communication to enhance the security and quality of traffic. The second end is to create a virtual testing environment to evaluate the quality of traffic, the assistance functions and the implemented communication models qualitatively and quantitatively.
As a summary, the following objectives are targeted in PLANETS: A dynamic management of traffic, flexible strategies of interactions for decentral Car-to-X communication and the establishment of a platform for simulation.
