The report documents design, development and testing of strategies for control of traffic within an urban freeway corridor, the Dallas, Texas, North Central Expressway Corridor. A multilevel control strategy was developed for four primary elements of the study: freeway, frontage roads, arterial streets, and driver information. A hardware system design was developed and a central computer and minicomputer system for corridor control was implemented. Strategies presented provide for real-time traffic responsive control in all phases. Freeway ramp metering rates are based on one minute speed and flow data, with response to individual gaps. Frontage road control provides for selection of three or four phase operation to accommodate progression optimization. Arterial control incorporates variable phasing and skip-phasing for this purpose. Frontage road and arterial control parameters are updated on a ten-minute basis.
