EQUILIBRIUM ASSIGNMENT FOR FIXED TRAVEL DEMAND: AN INITIAL APPRAISAL OF ITS PRACTICAL UTILITY

An analytic traffic assignment model (TRAFIC) has been modified to handle a variety of link supply functions, generalised cost functions for travel behaviour, and all or nothing, incremental (loading methods) in addition to equilibrium assignment techniques. At present the resultant program (ARRB-TRAFIC) is restricted to a fixed demand matrix. These three techniques are compared on a standard test problem to determine the relative effectiveness of each and the sensitivity to small changes is examined through road pricing (toll charging) on a link. Details are given of the potential applications to ATC appraisal, traffic management simulation, and environmental standard costing. /Author/
