Corridor / Congestion Management Program Area

Corridor/Congestion Management consists of the operational coordination of multiple transportation networks and cross-network connections comprising a corridor, and the coordination of stakeholders responsible for corridor mobility and congestion reduction. It includes managing the capacity from multiple transportation networks including freeways, arterials, and public transportation to improve the efficiency of the overall transportation system instead of individual sections of the roadway. This area focuses on maximizing throughput and reducing delays during normal travel conditions.

This is a primary NRO activity with cross-cutting applications and functions. Within NRO, the focus is to enable a coordinated approach to freeway, arterial management, and transit coordination. Freeway management is currently focused on improving the safety, efficiency, and reliability of travel on NRO freeway facilities. It includes a wide range of control strategies including ramp metering, mainline lane controls, HOV lanes, and gate-controlled reversible high occupancy vehicle (HOV) lanes. The Freeway Management System became operational in 1985 and is located in the Traffic Operations Center (TOC).

From the TOC, NRO monitors and manages traffic, recognizes and responds to incidents, and delivers traveler information to motorists. The TOC operates and controls field devices that are typically located along the roadside and which support traffic monitoring and traffic management. The TOC also coordinates with other agencies for responding to incidents and emergencies and participates in a regional incident management plan. The TOC manages the VDOT-owned traffic signals within the NRO boundaries.

The Northern Region relies heavily on the services provided by a number of transit agencies. WMATA provides transit bus and rail service and the Virginia Railway Express (VRE) provides commuter rail service in the Washington DC metropolitan area. NRO coordinates traffic, incident, and transit information through direct communications with the transit agencies. Traffic signal priority for transit buses is being considered by local jurisdictions as well as NRO to improve schedule adherence of transit agencies and the overall roadway network usage efficiency.
