- W2241431433 abstract "This paper presents the accident reduction effect found by installing roadway lighting in conformance with the American National Standard Practice for Roadway Lighting. A portion of Ogden Avenue in Naperville, Illinois, had only one block of modern lighting plus a few intersection lights in a length of 2.8 km. This five-lane roadway (two through lanes plus a center two-way left-turn lane) is 18 m wide. Street lighting was installed and maintained at a design level of 15 Lux, as appropriate for a major route in an intermediate area. A 4-year study of accidents was made, with 1984 and 1985 used in the before period and 1986 and 1987 in the after period. More than 800 accidents occurred during the total study period. Overall, accidents were reduced from 31% at night to 23% in the after period. The greatest reduction was in midblock locations, where the before percentage was 35 and the after was 21. The night accident reduction was 36%, calculated either on a night/day ratio of rates per million vehicle kilometers or by the simpler method of night percent change. If total day plus night accidents are considered, the overall accident reduction was 14%. An economic analysis, comparing the installation cost with the estimated cost of accidents prevented, showed payback in one year." @default.
