Roadway Intersection Safety Warning |
This equipment package includes field elements that monitor vehicles approaching and occupying an intersection and warns drivers when hazardous conditions are detected. It detects impending red-light or stop sign violations and potential conflicts between vehicles occupying and approaching an intersection. When a potentially hazardous condition is detected, a warning is communicated to the approaching vehicles using short range communications or signs/signals in the intersection. For signalized intersections, an interface to the signal controller allows this equipment package to monitor signal status and possibly change or extend the signal phase to reduce the risk of a collision. This equipment package is defined to support a range of implementation options including initial implementations that rely on sensors and intelligence embedded in the intersection to increase safety of a general vehicle population through implementations that communicate with and supplement a vehicle population that is equipped with vehicle-based sensors and short range communications that enable the vehicles to detect and warn their own drivers of hazardous situations. |
