Intersection Lighting Impacts on Nighttime Crashes Reduction and Safety Improvement

The Federal Highway Administration uses lighting as a significant countermeasure to increase roadway safety during nighttime. Statistics show that 25% of all motor vehicle travels occur at night, but approximately 50% of all traffic fatalities occur during nighttime. This research investigated the benefits of intersection lighting on the expected nighttime crashes reduction in both rural and urban intersections. Recent crash data from the Highway Safety Information System database for Minnesota and California were used to study the effect of intersection lighting on the expected nighttime crash frequency. The negative binomial regression model was used to analyze data. Overall, illuminated intersections showed a reduction of 3.61% and 6.54% in the expected nighttime crash frequency as compared to dark intersections in Minnesota and California, respectively.
