Title:

Analysis of Visual Performance Benefits from Roadway Lighting

Accession Number:

01710435

Record Type:

Monograph

Abstract:

As part of National Cooperative Highway Research Program (NCHRP) Project 5-19, several analyses of the visual performance of drivers under different roadway lighting conditions were conducted using simulations based on photometrically accurate lighting software. The analyses assessed the role of different lighting characteristics as they affect visibility for drivers of different age groups. Analyses were conducted using the relative visual performance model, a model of suprathreshold visibility based on the luminance contrast, background luminance, and size of a visual target. In general, the analyses were consistent with the notion that lighting generally improves visibility and by inference, safety, when it provides illumination where potential hazards are likely to be located.
