Title: REAL-TIME INCIDENT-RESPONSIVE SYSTEM FOR CORRIDOR CONTROL: MODELING FRAMEWORK AND PRELIMINARY RESULTS
Accession Number: 00676680
Record Type: Component
Availability: Find a library where document is available Abstract: An integrated optimal control model has been formulated to address the dynamic freeway diversion control process. An effective and efficient approach is developed for simultaneously solving diversion control measures, including on-ramp metering rates, off-ramp diversion rates, and green/Cycle ratios for traffic signals on a real-time basis. By approximating the flow-density relation with a two segment linear function, the nonlinear optimal control problem can be simplified into a set of piecewise linear programming models and solved with the proposed successive linear programming algorithm. Consequently, an effective on-line feedback approach has been developed for integrated real-time corridor control. Preliminary simulation results with INTRAS for a sample network have demonstrated the merits of the proposed model and algorithm.
