Step Up for Pedestrians at Night
In 2018, 76 percent of pedestrian fatalities in the U.S. occurred in dark conditions.1 Studies have identified a strong relationship between darker conditions and more severe injury pedestrian crashes.2 Appropriate lighting should increase visibility of pedestrian crosswalks and reduce glare for motorists. Illumination may also encourage more pedestrians to use crosswalks.3 Generally, overhead lights should be placed in advance of crosswalks and intersections, on both approaches, illuminating pedestrians from the sides and not creating overhead shadows on people crossing the road.4
At intersections, overhead lighting is estimated to reduce all types of injury crashes by 27%. Outside of intersections, overhead lighting improvements are estimated to reduce all types of injury crashes by 23%.5 Countermeasures such as high-visibility crosswalks and activated Rectangular Rapid Flashing Beacons increase visibility of pedestrians.
