AMPA Regional ITS Architecture Update

Element Expanded Functional Requirements: City of Rio Rancho ITS Field Equipment

Functional Area: Roadway Probe Data Communications
  1. The field element shall communicate with passing vehicles for traffic data link time calculations and send collected data to the controlling center; identification will be removed to ensure anonymity.
  2. The field element shall communicate with on-board equipment on passing vehicles to collect current vehicle position, speed, and heading and a record of previous events (e.g., starts and stops, link travel times) that can be used to determine current traffic conditions.
  3. The field element shall communicate with on-board equipment on passing vehicles to collect current status information and a record of previous events (e.g., temperature, wiper status, headlight status, traction control system status) that can be used to determine road and surface weather conditions.
  4. The field element shall communicate with on-board equipment on passing vehicles to collect vehicle trip information (e.g., origin and destination information, travel times) that can be used to support transportation planning.
  5. The field element shall communicate with on-board equipment on passing vehicles to collect a history of precise positioning information that can be used to derive or verify accurate roadway geometry and lane features for use by map update providers.
  6. The field element shall aggregate and forward collected probe information to the center.
  7. The field element shall provide roadside equipment operational status to the center.
  8. The field element shall provide roadside equipment fault indication to the center for repair.
Functional Area: Roadway Reversible Lanes
  1. The field element shall monitor traffic in reversible lanes, including wrong-way vehicles, using sensors and surveillance equipment under center control.
  2. The field element shall include automated reversible lane equipment and driver information systems (such as lane control signals) that control traffic in reversible lanes on surface streets, under center control.
  3. The field element shall include automated reversible lane equipment and driver information systems (such as lane control signals) that control traffic in reversible lanes on freeways, under center control.
  4. The field element shall provide operational status for the reversible lane field equipment to the center.
  5. The field element shall provide fault data for the reversible lane field equipment to the center.
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 Infrastructure Monitoring
  1. The field element shall include infrastructure condition monitoring sensors that monitor the condition of pavement, bridges, tunnels, associated hardware, and other transportation-related infrastructure (e.g., culverts), under maintenance center control.
  2. The field element shall include infrastructure condition monitoring sensors that monitor the condition of pavement, bridges, tunnels, associated hardware, and other transportation-related infrastructure (e.g., culverts), under maintenance vehicle control.
  3. The field element shall provide operational status for the infrastructure condition monitoring sensors to the maintenance center.
  4. The field element shall provide operational status for the infrastructure condition monitoring sensors to the maintenance vehicle.
  5. The field element shall provide fault data for the infrastructure condition monitoring sensors to the maintenance center for repair.
Functional Area: Field Secure Area Surveillance
  1. The field element shall include video and/or audio surveillance of secure areas including facilities (e.g. transit yards) and transportation infrastructure (e.g. bridges, tunnels, interchanges, roadway infrastructure, and transit railways or guideways).
  2. The field element shall be remotely controlled by a center.
  3. The field element shall provide equipment status and fault indication of surveillance equipment to a center.
  4. The field element shall provide raw video or audio data.
  5. The field element shall remotely process video and audio data and provide an indication of potential incidents or threats to a center.
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.
