The concept of Managed Freeways builds upon the Intelligent Transportation Systems (ITS) applications of ramp metering, Active Traffic Management (ATM), and the dynamic demand management capability of managed lanes to implement a comprehensive package of strategies to fully manage access to and demand for a freeway facility. Managed Freeways are urban freeways that utilize integrated data collection sensors along the roadway and advanced system management tools to monitor and control real time traffic conditions to ensure a higher and more consistent level of freeway performance. By utilizing intelligent information, communications and control systems, Managed Freeways systems synchronize the flow of vehicles entering a freeway to those already on the freeway to match the operational capacity. This real time, comprehensive demand management results in considerable improvements in freeway performance and safety helping to maximize the overall efficiency of the facility.
Components of a Managed Freeway can include extensive vehicle detection and data collection systems, coordinated ramp metering, variable speed limits and lane control, incident detection, traveler information and closed circuit television surveillance along with lane-use management, variable pricing, priority vehicle queue bypass, and strategic design considerations (such as ramp queue storage, merge lanes, etc.).
