A system for deployment of traction enhancing agents uses an infrared detecting sensor to receive ambient IR from a roadway, whereby the road surface temperature is determined. The determined temperature is supplied to a traction enhancing agent deployment controller, so that the amount and selection of particular agents can be governed based on the particular road surface temperature. Variations are thereby accommodated, so the most appropriate agent or agents in an appropriate combination and density can be applied.

Traction enhancing deployment system

An imminent icing condition detector employs an infrared sensor with a focusing element to receive ambient infrared energy from a surface, particularly a road surface, and the output of the sensor is processed to provide an indication of the likelihood of icing conditions and to accordingly control a traction control substance deployment system, such as a truck that dispenses a de-icing, anti-icing, or traction substance, such as sand, salt, or other material or mixture of materials in solid granular, liquid, or mixed form.

Imminent icing condition enunciator

An imminent icing condition enunciator employs an infrared sensor with a focusing element to receive ambient infrared energy from a surface, particularly a road surface, and the output of the sensor is processed to provide an indication of imminent icing to the operator of, for example, an automobile or other vehicle. The device is suitably mounted to a vehicle, within a mirror enclosure so as to provide an unobstructed view of the roadway surface.
