AN INTEGRATED OPTIMAL CONTROL MODEL FOR URBAN FREEWAY CORRIDOR SYSTEMS

An integrated optimal control model has been formulated to address dynamic urban freeway corridors optimal control process. The purpose of this paper is to develop an effective approach for simultaneously solving optimal control measures, including on-ramp metering rates, off-ramp diversion rates, and g/C ratios for traffic signals, on a real-time basis. By approximating the flow-density relation with a two-segment linear function, the non-linear optimal control problem can be simplified into a set of piece-wised linear programming models and solved with the proposed SLP (Successive Linear Programming) algorithm. Consequently, an effective on-line feedback method has been developed for integrated urban freeway corridor control in the framework of the ITS. For the covering abstract see IRRD E102946.
