In recent years, on-ramp control and freeway redesign to improve freeway traffic operations has received considerable attention. Concurrently, work has been under way to develop coordinated control and design systems to improve street operations. However, only a few studies have used an integrated approach, to control and design both a freeway and an adjacent street network (i.e., an urban freeway corridor). Since corridor control and design systems have already been implemented in some locations and are planned in others, it would be most appropriate to have a methodology available that simultaneously considered all pertinent corridor control and design variables, such as ramp-metering rates, traffic signal timings, quantity of traffic to be diverted, and corridor geometry. The objectives of this study are (1) the development of such methodology and (2) the application of the methodology to corridor control optimization. As an example, the methodology is applied to the determination of optimum fixed-time corridor control strategies using data from the Northbound Eastshore Freeway Corridor (I-80) in the San Francisco Bay Area. Such research is expected to provide optimum corridor control strategies and to stimulate improved usage of existing facilities by balancing traffic against available capacity throughout a corridor system.
