DEVELOPMENT OF WARRANTS FOR RURAL AT-GRADE INTERSECTION ILLUMINATION
A methodology is formulated that measures the effects of illumination of rural at-grade intersections in quantifiable terms. Previous research indicated that accident reduction is a valid criteria for evaluating lighting effectiveness. The effectiveness of illumination in modifying seven accident measures was evaluated by an analysis of variance. No significant relationship between accident severity and illumination could be inferred from the data. A predictor of accident reduction was developed based on the ratio of night accidents to total accidents after illumination. Values derived using the predictor were found to agree reasonably well with actual values obtained in two previous studies. (Author Modified Abstract)
