National ITS Architecture Functional Requirements
associated with VDOT Midtown 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 Freeway Management
  1. The center shall remotely control systems to manage use of the freeways, including ramp meters, mainline metering, and lane controls.
  2. The center shall collect operational status from ramp meters, mainline metering, and lane controls and compare against the control information sent by the center.
  3. The center shall collect fault data from ramp meters, mainline metering, and lane controls.
  4. The center shall implement control strategies, under control of center personnel, on some or all of the freeway network devices (e.g. ramp meters, mainline metering, and lane controls), based on data from sensors monitoring traffic conditions upstream, downstream, and queue data on the ramps themselves.
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.
  2. The center shall exchange traffic control information with other traffic management centers to support remote monitoring and control of traffic management devices (e.g. signs, sensors, signals, cameras, etc.).
TMC Incident Detection
  1. 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.
  2. The center shall collect and store traffic flow and image data from the field equipment to detect and verify incidents.
  3. The center shall receive inputs concerning upcoming events that would effect the traffic network from event promoters, traveler information service providers, border crossings, and intermodal freight depots.
  4. 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.
  5. The center shall provide road network conditions and traffic images to emergency management centers to support the detection, verification, and classification of incidents.
  6. The center shall provide video and traffic sensor control commands to the field equipment to detect and verify incidents.
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.
