A METHOD AND SYSTEM FOR DETECTING AND ESTIMATING ROAD TRAFFIC FROM LOCATION DATA OF MOBILE TERMINALS IN A RADIOCOMMUNICATION SYSTEM, SO AS A PROGRAM THEREFOR

摘要

The invention relates to a method and a system for detection and estimation of road traffic on the basis of position-locating information on mobile terminals of a radio communication system. The method determines if a mobile terminal under consideration is in motion or is stationary, then if it is located inside or outside of the road section under surveillance. From the knowledge of the position and speed of displacement of each mobile it is evaluated if the road traffic is flowing or slowing, and -if at least one terminal belonging to the road section is stationary, it checks if a traffic jam situation exists and if the stationary mobile is involved in it.
