This research was undertaken to evaluate the cost-benefits of arterial lighting treatments in terms of traffic safety and eneryg use. As a result, a Design Guide has been developed to assist potential users in conducting cost-benefit analyses of lighting changes at specific locations. This Design Guide provides instructions for using a computer program to determine visibility on arterial streets and a method for conducting a cost-benefit analysis of new and upgraded lighting systems. In addition to this Design Guide, a Final Report (FHWA-RD-77-37) has been prepared to summarize the results of this research. The results have shown that arterial streets with high population density, in CBD areas, with low visibility have higher accident potential than arterial streets with low population density, in Other areas with high visibility. Regression equations have been developed which predict dry, nighttime accident potential based on population density, area type and visibility. In addition, the results have also shown that more cost beneficial lighting systems can be designed using HPS rather than Mercury luminaires. /Author/
