AMPA Regional ITS Architecture Update

Element Expanded Functional Requirements: City of Albuquerque DMS

Functional Area: Roadway Traffic Information Dissemination
  1. The field element shall include dynamic messages signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).
  2. The field element shall include driver information systems that communicate directly from a center to the vehicle radio (such as Highway Advisory Radios) for dissemination of traffic and other information to drivers, under center control.
  3. The field element shall include pedestrian information systems under center control (e.g. warning pedestrians of a potential hazard, or providing mandatory instructions as to the availability of pedestrian access).
  4. The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.
  5. The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the 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: 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.
