For the Washington Post, Ian Duncan, Emmanuel Martinez, and Dylan Moriarty analyzed traffic fatality data from the National Highway Traffic Safety Administration:
The Post analysis documents, for the first time, a sharp increase in places with clusters of pedestrian deaths, revealing the deadliest neighborhoods and stretches of road in hundreds of cities. The number of locations with at least three recent pedestrian deaths clustered within a mile of one another tripled during this period, from more than 275 in 2010 to more than 825 in 2023, The Post found. Those hot spots increased most in states in the southern half of the country such as Tennessee, North Carolina and Arizona.
A searchable map lets you see incident counts in places of interest, which is unsettling when you see dots and hexagons not far from where you live.
