Pedestrian fatality risk by lighting condition, 2022 analysis

Analysis of pedestrian injuries and deaths across the injury-severity spectrum by lighting condition. The majority of pedestrian fatalities occur in darkness, and night-time pedestrian deaths have risen far faster than daytime deaths over the past decade; being struck in the dark substantially raises the odds that a collision is fatal, and unlit locations carry markedly higher fatality risk than lit ones. This is traffic-collision data on pedestrians, not runners, so it supports only the general points that darkness raises risk and that lit routes are safer than unlit ones. No running-specific collision or night-time fall dataset was located, so the trip-and-fall risk of running on unlit ground is inferred from footing evidence rather than measured.
