A SYSTEMS DYNAMICS APPROACH TO THE ESTIMATION OF ENTRY AND EXIT O-D FLOWS

After a review of recent approaches to determine traffic flows from traffic counts at complex traffic facilities a new method for the estimation of the origin-destination matrix is presented. For this purpose traffic flow in the facility is treated as a dynamic process. The model uses the information contained in the time sequences of the traffic volumes at the entries and exits at a complex intersection and solves the problem with a parameter optimisation technique satisfying the given constraints exactly. The comparison with real and synthetic data proved the new method to be superior to previously published approaches to the problem. Because of the efficiency of the algorithm, the procedure could be implemented on a microcomputer at the control site giving online the data basis for traffic responsive control. (Author/TRRL)
