Abstract	The need for a highway fog warning system has long been internationally recognized. With such a system, motorists can avoid tragic pile-up accidents caused by dense or patchy fog. The development of a cost-effective highway visibility sensor that measures the density of roadway fog and is linked to traveler information systems could substantially reduce fog accidents. With this in mind, FHWA conducted a study - summarized in this brief - to develop a low-cost, reliable fog sensor.
