Functional Requirements:

Roadway Basic Surveillance

  • 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.
  • The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
  • The field element shall return sensor and CCTV system operational status to the controlling center.

Roadway Short Range Traveler Information Communications

  • The field element shall distribute traveler information including traffic and road conditions to passing vehicles using short range communications, under center control.
  • The field element shall distribute advisory information, such as evacuation information, wide-area alerts, incident information, work zone intrusion information, and other special information to passing vehicles using short range communications, under center control.

Roadway Incident Detection

  • The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
  • The field element shall remotely process video data and provide an indication of potential incidents to the traffic management center.

Roadway Signal Controls

  • The field element shall control traffic signals under center control.
  • The field element shall respond to pedestrian crossing requests by accommodating the pedestrian crossing.
  • The field element shall provide the capability to notify the traffic management center of pedestrian calls and pedestrian accommodations.
  • The field element shall return traffic signal controller operational status to the center.

Roadway Traffic Information Dissemination

  • 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).
  • 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).

Roadway Equipment Coordination

  • The field element shall include sensors that provide data and status information to other field element devices, without center control.

Roadway Work Zone Safety

  • 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.
  • 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.
  • The field element shall provide operational status for the work zone intrusion detection devices to the maintenance center.
  • The field element shall provide operational status for the work zone intrusion alerting devices to the maintenance center.

Roadway Work Zone Traffic Control

  • The field element shall collect, process, and send work zone images to the center for further analysis and distribution, under center control.
  • 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.

Roadway Field Device Monitoring

  • 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).
  • The field element shall send operational status of connected field equipment to the maintenance center.
  • The field element shall include a local interface that provides operational status and fault data for connected field equipment to field personnel.

Field Management Stations Operation

  • The field management station shall accept configuration information from the center.
  • The filed management station shall pass data provided by the center to local field devices and report data from the field devices back to the center.
