INFLUENCE OF CONTROL MEASURES ON TRAFFIC EQUILIBRIUM IN AN URBAN HIGHWAY NETWORK

Traffic control measures play a critical role in determining equilibrium between demand and supply in an urban highway network. Present techniques attempt to optimize network performance assuming a fixed demand pattern. Experience indicates that control measures can be used to influence demand patterns in such a way that total network performance is significantly improved. On the basis of the interdependence of control measures and resulting traffic flow patterns, this paper develops an analytical framework for at systematic optimization of the operation of a highway system. Two practical examples demonstrate such an optimization on a limited scale, and a model and a mathematical program for achieving it are presented. /Author/
