A macroscopic freeway simulation model is developed to evaluate and compare various freeway control strategies. The resulting model, FRECON, is a properly discrete extension of the dynamic FREFLO model. The model is calibrated and validated on five days of data from the Santa Monica Freeway. Control Strategies are divided into three configurational groups: pretimed, local traffic responsive, and segment-wide traffic responsive. Simulation evaluations, without vehicle diversion or priority treatment, are performed for one pretimed strategy (Linear Programming) and two local strategies (Percent Occupancy and Demand-Capacity). By not responding to daily variations in the traffic demands, the quality of the pretimed strategy's performance is limited. The local view of freeway conditions used by the local traffic responsive strategies limits their ability to control the freeway. A preliminary analysis of segment-wide traffic responsive strategies is also made.
