On-The-Fly Location Referencing Methods for Establishing Traffic Information Services

The paper presents different use cases for location referencing. It shows how a full service chain for traffic information services could be established and gave an overview of the widely used method traffic message channel (TMC). After a discussion about the growing requirements of telematics systems, a new approach to location referencing is presented: the on-the-fly methods. The difficulties regarding the development of on-the-fly methods was discussed and present the AGORA-C method which is currently in the standardisation process. An overview of the publicised test results using the AGORA-C method concerning its reliability and applicability was given. In addition, another algorithm for location referencing, MEI-LIN, was presented which focuses on a better identification of a location using topological information of the surrounding road network. An outlook on the current research in Europe shows the main future tasks of establishing location referencing methods
