Real-time information about average speeds on links in a road network constitutes a very important component of efficient traffic management. Using this information enables to detect congestions, calculate travel times, predict future traffic situations and hence have a good base for correct traffic management measures. These measures are in turn important in order to reduce the environmental footprint from road traffic and decrease travel times. Retrieval of this information through the signalling information already available in cellular system is an efficient and scalable way of obtaining data. This information is available in GSM, UMTS and other cellular systems.
The aim of our work is to assess the potential of new technologies and communication patterns for extracting more accurate and reliable traffic information. To this end we also develop new algorithms and simulation models to distil cellular signalling data into useful traffic information. Read more
