Abstract:
Roadway lighting is provided on selected highways to improve the visibility and safety of the nighttime driving environment. Roadway lighting is typically installed due to traffic volume warrants or safety criteria... Turning off or reducing the lighting level during late-night periods is known as a lighting curfew. The potential benefits of implementing a lighting curfew include reduced energy consumption and the associated electrical cost for the agency responsible for the lighting plus reduced light pollution and spillover onto adjacent properties... This research project evaluated the potential benefits of turning off roadway lighting on freeways during the late night and/or early morning hours. The researchers, in consultation with the Texas Department of Transportation (TxDOT) project advisors, decided to focus on freeways because of the prevalence and the accessibility of traffic volume and crash data to analyze the safety impacts of a lighting curfew.
