Element Expanded Functional Requirements: Bernalillo County Field Sensors

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 Data Collection
  1. The field element shall collect traffic, road, and environmental conditions information.
  2. The field element shall include the sensors and supporting roadside devices that sense, collect, and send traffic, road, and environmental conditions information to a center for archival.
  3. The field element shall collect sensor status and sensor faults from roadside equipment and send it along with the recorded data to a center for archival.
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 Field Device Monitoring
  1. The field element shall monitor the operational status (state of the device, configuration, and fault data) of connected sensors (such as traffic, infrastructure, environmental, security, speed) and devices (such as highway advisory radio, dynamic message signs, automated roadway treatment systems, barrier and safeguard systems, cameras, traffic signals, ramp meters, short range communications equipment, security surveillance equipment).
  2. The field element shall send operational status of connected field equipment to the maintenance center.
  3. The field element shall send collected fault data to the maintenance center for repair.
  4. The field element shall include a local interface that provides operational status and fault data for connected field equipment to field personnel.
  5. The field element shall include a local interface that allows field personnel to command diagnostic tests on connected field equipment.
