Included In
Functional Requirements
| ID | Requirement |
|---|---|
| 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. |
