NoVA STC - Inventory Element

VDOT NoVA STC- Inventory Element

Interconnects -- Flows -- Entities -- Market Packages -- Functional Area

Status: Existing

Definition: This element represents the proposed integration between existing transportation and mangement systems in VA, MD and DC into a regionNOVA STC is a nerve center of an integrated system of advanced technologies including computer software, traffic cameras, lane control strategies, ramp meters, reversible control gates, and HOV lane restrictions. From the STC, VDOT monitors and manages traffic, recognizes and responds to incidents, and instantly delivers information to motorists. VDOT Northern Virginia Smart Traffic Center is responsible for monitoring and managing traffic conditions on I-495, I-95/395, and I-66. The STC will be part of the PSTOC in the near future.

Stakeholder: VDOT NoVA District

National ITS Architecture Functional Area associated with VDOT NoVA Smart Traffic Center:

Collect Traffic Surveillance - Management of traffic sensors and surveillance (CCTV) equipment, and distribution of the collected information to other centers and operators.
ITS Data Repository - Collect and maintain data and data catalogs from one or more data sources. May include quality checks, error notification, and archive coordination.
Service Patrol Management - Dispatch and communication with roadway service patrol vehicles that monitor roads to aid motorists, offering rapid response to minor incidents.
TMC Environmental Monitoring - Management of environmental sensors and assimilation of collected data with other current and forecast road conditions and surface weather information from weather service providers and roadway maintenance operations.
TMC Evacuation Support - Development, coordination, and execution of special traffic management strategies during evacuation and subsequent reentry of a population in the vicinity of a disaster or major emergency. Interfaces with emergency management and other traffic management centers.
TMC Freeway Management - Remotely controls ramp meters, mainline metering, and lane controls on freeways based on upstream and downstream traffic flow and ramp queue length algorithms.
TMC HOV Lane Management - Remotely controls high-occupancy vehicle (HOV) lane sensors, driver information systems, and ramp meters to manage use of HOV or High Occupancy Toll (HOT) lanes; also detects HOV violators and notifies enforcement agencies.
TMC Incident Detection - Remotely controls traffic and video sensors to support incident detection and verification; exchange information with other agencies including emergency management, maintenance and construction, alerting and advisory systems, event promoters, intermodal freight depots, and traveler information systems.
TMC Incident Dispatch Coordination/Communication - Center-based capability to formulate an incident response that takes into account the incident potential, incident impacts, and/or resources required for incident management including proposing and facilitating the dispatch of emergency response and service vehicles as well as coordinating response with all appropriate cooperating agencies.
TMC Probe Information Collection - Collects, assimilates, and disseminates vehicle probe data collected from roadside beacons and centers controlling transit vehicles, emergency vehicles, toll collection points, and route-guided vehicles.
TMC Reversible Lane Management - Remotely controls traffic sensors, surveillance, and automated reversible lane equipment and lane control signals to control traffic in reversible lanes.
TMC Traffic Information Dissemination - Controls dissemination of traffic-related data to other centers, the media, and travelers via the driver information systems (DMS, HAR) that it operates.
TMC Traffic Network Performance Evaluation - Systems to predict travel demand patterns to support traffic flow optimization, demand management, and incident management. Collects data from surveillance equipment as well as input from other management centers including emissions, event promoters, and other TMCs.
TMC Work Zone Traffic Management - Coordination with maintenance systems using work zone images and traveler information systems (such as DMS), and distribution of work plans so that work zones are established that have minimum traffic impact.
Traffic and Roadside Data Archival - Collects and archives traffic and environmental information directly from the roadside for use in off-line planning, research, and analysis.
Traffic Data Collection - Collection and storage of traffic management data. For use by operations personnel or data archives in the region.
