Functional Requirements: Roadway Intersection Collision Warning |
|
Description: |
This equipment package includes field elements that determine the probability of a collision in an intersection by monitoring vehicles approaching the intersection. When a potential collision is detected, this equipment package sends appropriate warnings and/or control actions to the approaching vehicles using a short-range interface. It also provides signal indication information to approaching vehicles to improve intersection safety. This equipment package covers any signalized intersection equipped with intersection collision warning field equipment. |
Functional Requirements: |
- The field element shall utilize traffic sensors to monitor vehicles approaching and occupying an intersection.
- The field element shall monitor the operational state, signal timing, and current phase of the traffic signal.
- The field element shall monitor road conditions on approaches to, and within, the intersection.
- The field element shall communicate with approaching vehicles to determine vehicle position, velocity, acceleration, direction, and intended turning movement.
- The field element shall detect potentially hazardous conditions including impending red-light or stop sign violations and potential conflicts between approaching vehicles.
- The field element shall provide intersection status and warnings to approaching vehicles using field-vehicle communications.
- The field element shall update signs or signals to warn the driver of potentially hazardous situations.
