REAL-TIME INCIDENT-RESPONSIVE CORRIDOR CONTROL: A SUCCESSIVE LINEAR PROGRAMMING APPROACH

This study's purpose is to develop an integrated, optimal control model to address the dynamic traffic diversion control issues for freeway corridors. The goal is to explore an effective and efficient approach for simultaneously solving diversion 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-wise linear programming models and solved with the proposed SLP algorithm. Consequently, an effective on-line feedback approach has been developed for integrated real-time corridor control.
