SIMULATION OF FREEWAY STRATEGIES (FREQ3CP)

This report describes the development, computerization, and application of an analytical procedure for entry control at freeway ramps. Two types of control strategies are developed: control on a passenger basis and control on a vehicle basis. The analytical procedure encompasses two models. The first is a simulation model which is deterministic and macroscopic, that predicts the freeway traffic performance as a function of freeway design and allowable ramp flows. The second is a decision model, which has a linear programming formulation, that selects a control strategy meeting the objectives and constraints. The simulation model was validated under field conditions, and the predicted traffic performance compares very favorably to actual, measured traffic performance. The two models were integrated and computerized, and the composite model was applied to a number of sites to demonstrate its applications and to provide some results for possible implementation.
