National ITS Architecture Functional Requirements
associated with VDOT Joint Berkley Bridge- Downtown Elizabeth River Tunnel TOC:

Center Secure Area Surveillance

1. The center shall remotely monitor video images and audio surveillance data collected in secure areas including facilities (e.g. transit yards) and transportation infrastructure (e.g. bridges, tunnels, interchanges, roadway infrastructure, and transit railways or guideways). The data may be raw or pre-processed in the field.
2. The center shall exchange surveillance data with other emergency centers.
3. The center shall identify potential security threats based on collected security surveillance data.
4. The center shall remotely control security surveillance devices in secure areas including facilities (e.g. transit yards) and transportation infrastructure (e.g. bridges, tunnels, interchanges, roadway infrastructure, and transit railways or guideways).
5. The center shall respond to control data from center personnel regarding security surveillance data collection, processing, threat detection, and image matching.
6. The center shall monitor maintenance status of the security sensor field equipment.

Center Secure Area Sensor Management

1. The center shall remotely monitor and control security sensor data collected in secure areas including facilities (e.g. transit yards) and transportation infrastructure (e.g. bridges, tunnels, interchanges, roadway infrastructure, and transit railways or guideways). The types of security sensor data include environmental threat (e.g. chemical agent, toxic industrial chemical, biological, explosives, and radiological sensors), infrastructure condition and integrity, intrusion and motion, and object detection sensors. The data may be raw or pre-processed in the field.
2. The center shall exchange security sensor data with other emergency centers.
3. The center shall identify potential security threats based on collected security sensor data.
4. The center shall disseminate threat information to other agencies, including traffic, transit, maintenance, rail operations, and other emergency management centers.
5. The center shall request activation of barriers and safeguards on request from center personnel.
6. The center shall monitor maintenance status of the security sensor field equipment.

Center Secure Area Alarm Support

1. The center shall collect silent and audible alarms received from travelers in secure areas (such as transit stops, rest areas, park and ride lots, modal interchange facilities).
2. After the alarm message has been received, the center shall generate an alarm acknowledgment to the sender.
3. After the alarm message becomes a verified incident, the center shall determine the appropriate response.
4. The center shall determine whether the alarm message indicates an emergency that requires the attention of public safety agencies, and forward alarm message data to the appropriate agency as necessary.
5. The center shall forward the alarm message to center personnel and respond to the traveler or transit vehicle operator as directed by the personnel.

TMC Traffic Information Dissemination

1. The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
2. The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.
3. The center shall retrieve locally stored traffic information, including current and forecasted traffic information, road and weather conditions, traffic incident information, information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements), and the definition of the road network itself.
4. The center shall distribute traffic data to maintenance and construction centers, transit centers, emergency management centers, and traveler information providers.

TMC Incident Detection

1. The center shall collect and store traffic flow and image data from the field equipment to detect and verify incidents.
2. The center shall exchange incident and threat information with emergency management centers as well as maintenance and construction centers; including notification of existence of incident and expected severity, location, time and nature of incident.
3. The center shall provide road network conditions and traffic images to emergency management centers to support the detection, verification, and classification of incidents.
4. The center shall provide video and traffic sensor control commands to the field equipment to detect and verify incidents.

TMC Incident Dispatch Coordination/Communication

1. 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. The information may include the alert originator, the nature of the emergency, the geographic area affected by the emergency, the effective time period, and information and instructions necessary for the public to respond to the alert. This may also identify specific information that should not be released to the public.
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 incident information with emergency management centers, maintenance and construction centers, transit centers, information service providers, and the media including description, location, traffic impact, status, expected duration, and response information.
4. The center shall provide road network conditions and traffic images to emergency management centers, maintenance and construction centers, and traveler information service providers.
5. The center shall exchange road network status assessment information with emergency management and maintenance centers including an assessment of damage sustained by the road network including location and extent of the damage, estimate of remaining capacity, required closures, alternate routes, necessary restrictions, and time frame for repair and recovery.
6. The center shall coordinate information and controls with other traffic management centers.

Traffic Data Collection

1. The center shall collect traffic management data such as operational data, event logs, etc.
2. The center shall assign quality control metrics and meta-data to be stored along with the data. Meta-data may include attributes that describe the source and quality of the data and the conditions surrounding the collection of the data.
3. The center shall receive and respond to requests from ITS Archives for either a catalog of the traffic data or for the data itself.
4. The center shall be able to produce sample products of the data available.
