AMPA Regional ITS Architecture Update

Element Expanded Functional Requirements: NMDOT CCTV

Functional Area: Roadway Basic Surveillance
  1. The field element shall collect, process, digitize, and send traffic sensor data (speed, volume, and occupancy) to the center for further analysis and storage, under center control.
  2. The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
  3. The field element shall collect, digitize, and send multimodal crossing and high occupancy vehicle (HOV) lane sensor data to the center for further analysis and storage.
  4. The field element shall return sensor and CCTV system operational status to the controlling center.
  5. The field element shall return sensor and CCTV system fault data to the controlling center for repair.
  6. The field element shall return CCTV system operational status to the controlling center.
  7. The field element shall return CCTV system fault data to the controlling center for repair.
  8. The field element shall return sensor system operational status to the controlling center.
  9. The field element shall return sensor system fault data to the controlling center for repair.
Functional Area: Roadway Equipment Coordination
  1. The field element shall include sensors that provide data and status information to other field element devices, without center control.
  2. The field element shall include sensors that receive configuration data from other field element devices, without center control.
  3. The field element shall include devices that provide data and status information to other field element devices without center control.
  4. The field element shall include devices that receive configuration data from other field element devices, without center control.
Functional Area: Roadway Work Zone Traffic Control
  1. The field element shall collect, process, and send work zone images to the center for further analysis and distribution, under center control.
  2. Under traffic and maintenance center control, the field element shall include driver information systems (such as dynamic messages signs and highway advisory radios) that advise drivers of activity around the work zone through which they are currently passing.
  3. Under the control of field personnel within maintenance vehicles, the field element shall include driver information systems (such as dynamic messages signs and highway advisory radios) that advise drivers of activity around a work zone through which they are currently passing.
  4. The field element shall control access to the work zone using automated gate or barrier systems. This includes automated flagger assistance devices that include automated gate arms and other automated gate/barrier systems.
  5. The field element shall provide operational status for the surveillance (e.g. CCTV), driver information systems, and gates/barriers in work zones to the maintenance center.
  6. The field element shall provide fault data for the surveillance (e.g. CCTV), driver information systems, and gates/barriers in work zones to the maintenance center for repair.
Functional Area: Field Barrier System Control
  1. The field element shall activate barrier systems for transportation facilities and infrastructure under center control. Barrier systems include automated or remotely controlled gates, barriers and other systems that manage entry to roadways.
  2. The field element shall return barrier system operational status to the controlling center.
  3. The field element shall return barrier system fault data to the maintenance center for repair.
  4. The field element shall receive requests for access from approaching vehicles using field-vehicle communications and validate and authenticate the requests.
  5. The field element shall grant access only to qualified vehicles.
  6. The field element shall communicate access permission status and access instructions to approaching vehicles using field-vehicle communications.
