NUMERICAL FILTERING AND AUTOMATIC CONTROL OF TRAFFIC

FILTRAGE NUMERIQUE ET CONTROLE AUTOMATIQUE EN TRAFIC ROUTIER

The control and regulation of traffic on access motorways to large urban areas (corridors) necessitates a knowledge of several traffic indicators. This paper develops a calculation method for certain of these parameters: mean speed, number of vehicles, density. The method employed uses the kalman filter, particularly adapted to digital calculation. The algorithms obtained have been tested using actual data obtained from tests on certain sections of the A13 motorway outside Paris. /TRRL/
