ROAD LIGHTING - VISIBILITY AND ACCIDENT REDUCTION

Money is spent on lighting roads primarily because of improved safety. Such matters as civic pride, public amenity and driver comfort may be brought into the argument, but if it were not believed that fixed lighting has a significant effect on road accidents we would not have the mileage of traffic route lighting we enjoy today. The first section of this paper summarises the evidence linking road lighting and accident reduction. Since this link is presumably a consequence of improved visibility, it should be possible to make some theoretical predictions about the benefits of road lighting from a knowledge of human visual performance characteristics. Such predictions are made in the second section of this paper, but the limitations of trying to apply visual detection theory to the complex task of a vehicle driver are explained. Finally, an outline is given of a practical approach to studying the relation between road lighting and accidents, with some details of the techniques used to record and analyse the dynamic visual field of a vehicle driver. /TRRL/
