Paper Abstract

A nonlinear programming model was formulated to provide an integrated traffic control strategy for a freeway corridor under incident conditions. The model includes diversion routes, diversion rates, on- and off-ramp metering rates, and arterial intersection timing plans as control variables. A gradient projection algorithm was employed to solve simultaneously the optimal control measures. The model performance was evaluated and validated by running the simulation and optimization programs of TRANSYT-7F and INTEGRATION. It has been found that the proposed model and control strategy reduce the overall system delay, increase the throughput of the corridor, and thus improve the traffic conditions of the entire corridor.
