Crash Modification Factor and Feasibility Analysis of Lighting Rural Intersections in Nebraska

Intersection lighting is an important countermeasure intended to enhance safety for drivers during nighttime. According to the National Highway Transportation Safety Administration (NHTSA), nighttime driving conditions account for more than 40% of fatalities, although only 27% of crashes occur at night (NHTSA, 2012). Federal Highway Administration (FHWA) reported that the number of fatal crashes occurring in daylight is about the same as those that occur in darkness. However, the nighttime fatality rate is three times greater than the daytime rate because only 25% of vehicle miles traveled (VMT) occur at night (FHWA, 2023). FHWA and other studies reported that installing lights at the intersection may reduce accidents by around 30% to 40% (FHWA, 2023; Bruneau and Morin, 2005).
