THE EFFECT OF PRESENCE LIGHTS ON THE DETECTION OF CHANGE OF VEHICLE HEADWAY

Previous experimental work has established a general relationship between light level and the detection of change in headway of a followed vehicle. It was assumed that the structure of the vehicle and its background had negligible effect on detection. Data are reported here on the effect of simulating vehicle presence lights. The results suggest that presence lights make an insignificant difference to the detection of change of headway. This is further evidence that the original relationship can be applied in practical situations with confidence. Implications of the results to fixed and vehicle lighting design ar discussed. /Author/TRRL/
