Element Expanded Functional Requirements: NMDOT Work Zone Equipment

Functional Area: Roadway Work Zone Safety
  1. The field element shall include work zone intrusion detection devices that detect when a vehicle has intruded upon the boundary of a work zone, under center control.
  2. The field element shall include work zone intrusion detection devices that detect when crew workers have crossed the boundary between the work zone and vehicle traffic, under center control.
  3. The field element shall include work zone intrusion alerting devices that alert crew workers of a work zone emergency or safety issue such as the intrusion of a vehicle into the work zone area or movement of field crew into the travel lanes.
  4. The field element shall include work zone intrusion alerting devices that notify crew via maintenance vehicles of a work zone emergency or safety issue such as the intrusion of a vehicle into the work zone area or movement of field crew into the travel lanes.
  5. The field element shall include work zone intrusion alerting devices that alert drivers that they have intruded upon the perimeter of the work zone, or are about to do so; may provide alerts to drivers directly or via in-vehicle signing.
  6. The field element shall provide operational status for the work zone intrusion detection devices to the maintenance center.
  7. The field element shall provide fault data for the work zone intrusion detection devices to the maintenance center for repair.
  8. The field element shall provide operational status for the work zone intrusion alerting devices to the maintenance center.
  9. The field element shall provide fault data for the work zone intrusion alerting devices to the maintenance center for repair.
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.
