Research series
Crash Atlas
A growing collection of city- and county-level studies of truck-involved fatal and severe-injury collisions across US metro areas. Each edition catalogs corridor-level patterns, time-of-day peaks, victim demographics, and pedestrian/cyclist deaths — all from publicly available crash records, with the raw data downloadable for republication.
Editions
-

About the series
Each Crash Atlas edition follows the same methodology: pull the relevant state's crash dataset (SWITRS in California, FARS for federal, plus state-specific equivalents elsewhere), restrict to truck-involved KSI (Killed or Severely Injured), clean and geocode, then publish the headline findings alongside the raw data.
The goal is to make corridor-level truck-crash data legible to journalists, transportation planners, and the general public — with citations to the original public sources and a downloadable dataset for anyone who wants to republish.
Coverage plan: California (Los Angeles → San Francisco Bay Area → Central Valley), Texas (Houston → Dallas/Fort Worth → San Antonio), Illinois (Chicago), Georgia (Atlanta), and Florida (Miami → Tampa → Jacksonville) over the next 12 months. The shared methodology page below explains the data layer behind every edition.
