Optimal control of multidestination traffic networks

Abstract

A macroscopic modeling framework for dynamic traffic phenomena on general multidestination networks with time-varying demands is developed. Route choice decisions are made according to the system optimum and the user optimum principle. Solution of the corresponding control problem is achieved by nonlinear optimal control and by feedback regulators. Results are relevant for modeling and control of urban traffic networks, freeway networks, and corridor networks including several control measures such as traffic signals, ramp metering, and route guidance. Examples are provided.< >
