| Abstract | This research was undertaken to evaluate the cost-benefits of arterial highway lighting treatments in terms of traffic safety and energy usage. The results have shown that total nighttime dry weather accidents are inversely related to visibility, higher visibility resulting in fewer accidents. Areas with high population densities have a much higher rate than low density areas and CBD areas have a much higher rate than other area types. Regression equations have been developed which predict dry nighttime accident history based on population density, area type and visibility. The results have also shown that more cost-beneficial lighting systems can be designed using HPS rather than Mercury luminaires although it is normally possible to use either source to obtain systems with benefit-cost ratio greater than 1. When visibility and accident reduction potential are the main constraints, optimum designs tend to use 400 HPS luminaires; when cost and energy use are the main constraints, 150 HPS luminaires tend to be optimum. In addition to this Final Report, a Design Guide (FHWA-RD-77-38( has been prepared to assist potential users in conducting cost-benefit analyses of lighting changes at specific locations. |
