Functional Areas
ISP Probe Information Collection
- The center shall collect traffic probe data (speeds, travel times, etc.) from appropriately equipped vehicles and short range communications equipment.
- The center shall aggregate collected traffic probe data, calculate route segment travel times, route segment speeds, and route usage, and disseminate to other centers.
Roadway Probe Data Communications
- 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.
- 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.
- The field element shall aggregate and forward collected probe information to the center.
- The field element shall provide roadside equipment operational status to the center.
- The field element shall provide roadside equipment fault indication to the center for repair.
TMC Probe Information Collection
- The center shall collect operational status for the roadside probe data collection equipment.
- The center shall collect fault data for the roadside probe data collection equipment for repair.
- The vehicle shall record vehicle trip information (e.g., travel times, origin and destination information for vehicles that opt in) that can be used to support transportation planning.
- The vehicle shall transmit collected probe data to the center.
- The vehicle shall transmit collected probe data to field equipment located along the roadway.
- The vehicle shall report the number of vehicle occupants to field equipment located along the roadway.
- The vehicle shall respond to requests from short range communications equipment for identification information that can be used to collect basic probe information; the field equipment will remove identification information to ensure anonymity.
- The vehicle shall track its current vehicle position, speed, and heading and record snapshots of events (e.g., starts and stops, link travel times) that can be used to determine current traffic conditions.
