Lots of stuff to learn from the 2007-2009 car crash data, with 309,425 crash reports.

What I noticed

  • SUV drivers do not cause all crashes, contrary to some stereotypes. That vehicle type (for both vehicle 1 and vehicle 2) is only involved in 45,776 crashes (14.79% of all crash reports)
  • The vehicle type most commonly involved in crashes is “personal passenger,” with 294,941 “personal passenger” vehicles involved in 208,888 crashes (67.51% of all crash reports)
  • 1,465 crash reports report “unknown” for both vehicle 1 type and vehicle 2 type (0.47% of all crash reports)
  • 61,645 crash reports have vehicle 1 hitting a parked car (19.92% of all crash reports)
  • There were 16,554 taxis involved in 15,223 crashes (4.92% of all crash reports). And there were 1,311 “taxi on taxi” crashes (0.42% of all crash reports)
  • 3,861 CTA transit buses (that can hold more than 15 passengers) were involved in 3,853 crashes (1.25% of all crash reports). And there were 8 “bus on bus” crashes (0.003% of all crash reports)
  • 1,644 school buses were involved in 1,635 crashes (0.53%). And there were 9 “school bus on school bus” crashes (0.003% of all crash reports)

Data does not include estimated cost of property damage.

Not all vehicles may be unique – some vehicles may be involved in more than one crash.
