National ITS Architecture Functional Requirements
associated with City of Richmond Traffic Operations Center:

TMC Incident Detection

1. The center shall receive inputs concerning upcoming events that would effect the traffic network from event promoters and traveler information service providers.
2. The center shall receive inputs from the Alerting and Advisory System concerning the possibility or occurrence of severe weather, terrorist activity, or other major emergency, including information provided by the Emergency Alert System.

TMC Basic Surveillance

1. The center shall maintain a database of surveillance equipment and sensors and associated data (including the roadway on which they are located, the type of data collected, and the ownership of each).
2. The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.

TMC Advanced Rail Crossing Management

1. The center shall accept collect highway-rail intersection (HRI) advisory or alert data from rail operations centers.
2. The center shall implement control plans to coordinate signalized intersections around highway-rail intersections (HRI), under control of center personnel, based on data from sensors and surveillance monitoring traffic conditions, incidents, equipment faults, pedestrian crossings, etc.

TMC Signal Control

1. The center shall manage (define, store and modify) control plans to coordinate signalized intersections, to be engaged at the direction of center personnel or according to a daily schedule.
2. The center shall remotely control traffic signal controllers.
3. The center shall collect traffic signal controller fault data from the field.
4. The center shall collect traffic signal controller operational status and compare against the control information sent by the center.

TMC Regional Traffic Management

1. The center shall exchange traffic information with other traffic management centers including incident information, congestion data, traffic data, signal timing plans, and real-time signal control information.

TMC Incident Dispatch Coordination

1. The center shall coordinate information and controls with other traffic management centers.
2. The center shall coordinate planning for incidents with emergency management centers - including pre-planning activities for disaster response, evacuation, and recovery operations.
3. The center shall exchange alert information and status with emergency management centers. The information includes notification of a major emergency such as a natural or man-made disaster, civil emergency, or child abduction for distribution to the public.
