Abstract
The present invention is a roadside safety system and method to communicate to a roadside personnel a potential danger created by an oncoming vehicle. The system includes a projection system that selectively projects a pattern of light in a direction along the roadside, a sensor system that includes a camera to detect the oncoming vehicle, an alert system connected directly or indirectly to the sensor system that selectively causes an alert to notify the roadside personnel when there is the potential danger; and a control system that selectively enables the projection system to project the pattern of light and causes the alert system to issue the alert. The projection system establishes a virtual flare on the road to warn oncoming vehicles of a emergency situation and a processor can process information received by the sensors and can then determine potential threats created by oncoming vehicles.
