Geographic and Time-of-Day Shifts in Pedestrian Crashes by Injury Severity Level

This project will explore geographic and time-of-day shifts in pedestrian crashes by injury severity level. Both fatal and non-fatal pedestrian injuries are important to understand due to their personal and societal costs, even though we lack a good national dataset that documents them. If all levels of injuries are shifting in a similar way as fatalities, then increases in fatalities may simply reflect higher pedestrian exposure overall, especially at certain locations and times. But if the more recent locations and times of crashes are associated with a more severe distribution of injuries, then the higher numbers of fatalities may be due to the same overall level of pedestrian activity shifting to locations and times that are prone to more severe injury outcomes. In either case, understanding where and when crashes are occurring—and why locations and times might be shifting—is essential to preventing future pedestrian injuries. The research team will use pedestrian injury severity data from at least 10 metropolitan regions from the 2010s and early 2020s to answer the following questions: (1) How much did fatal, severe, and non-severe pedestrian injuries change over the last decade? (2) What geographic shifts occurred in pedestrian crashes at each injury severity level over the last decade? (3) What time-of-day shifts occurred in pedestrian crashes at each injury severity level over the last decade? (4) Why did these geographic and temporal shifts in different injury levels occur?
