Traffic services for vehicles: the process from receiving raw probe data to space-time diagrams and theresulting traffic service

Markus AUER, Hubert REHBORN, Sven-Eric MOLZAHN, Micha KOLLER

Frontiers of Engineering Management 2017, Volume 4, Issue 4, Pages 490-497 doi: 10.15302/J-FEM-2017008

Abstract: Today, large quantities of vehicle data (FCD: floating car data) are widely used by traffic service providersto create and broadcast traffic states in road networks.After the matching process, space-time-diagrams are created of the probe data showing traffic situationVarious examples illustrate how traffic service quality depends on the number of matched GPS raw dataTraffic reconstruction is followed by a translation into traffic information messages, which can be sent
