Abstract

Collision deterrence system including signaling apparatus and method collision having frequency diversity, amplitude diversity, duty cycle diversity, and modal diversity and capable of being perceived by the following vehicle operator as being indicative of a lead vehicle motive state. The apparatus produces distinctive visual and aural signals constituting a characteristic hazard alert, representative of a lead vehicle motive state. The method generates an unambiguous signal representative of a predetermined hazard in the vehicle travel path. A collision deterrence diversity signaling method provides unique visual and audible signals directed toward a following vehicle operator, eliciting a REC avoidance response.
