Pedestrian-related crashes are a common cause of roadway fatalities, and reduced visibility at night is a probable contributor to pedestrian injuries and death. The purpose of the present study was to systematically evaluate different approaches to lighting at pedestrian crosswalks to improve pedestrian visibility and detection. The project team conducted a series of photometrically accurate lighting simulations in order to assess the visual conditions resulting from different lighting configurations, and assessed the economics (initial cost, and electricity and maintenance costs) of each system evaluated. Finally, the most promising lighting configuration was field tested during a one-night demonstration at an intersection in New Jersey. |
