Element Expanded Functional Requirements: NMDOT Roadway Treatment Devices

Functional Area: Roadway Automated Treatment
  1. The field element shall activate automated roadway treatment systems based on environmental or atmospheric conditions. Treatments can be in the form of fog dispersion, anti-icing chemicals, etc.
  2. The field element shall activate automated roadway treatment systems under center control. Treatments can be in the form of fog dispersion, anti-icing chemicals, etc.
  3. The field element shall return automated roadway treatment system and associated environmental sensor operational status to the maintenance center.
  4. The field element shall return automated roadway treatment system and associated environmental sensor fault data 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.
