Sighting Safety

Document Type: Proceeding Paper

Part of: Effectiveness of Highway Safety Improvements


This paper examines the interrelation between drivers' visual needs and the road environment. Specific elements of visual limitation and drivers at greatest risk are identified. This paper presents statistical evidence that such visually limited drivers' crash experience is worse on those road systems which provide less visual information, and worst when their ability to see is even further reduced by darkness. Cost-effective road safety improvements can reduce crash risk of visually limited drivers, and all road users. The effectiveness of one such improvement - the use of wider-than-standard, 8' edgelines - is documented.
