Questions
Dangerous intersections — FAQ
What is the most dangerous intersection in Tucson?
In the official records we hold (1 Jan 2026 – 19 Oct 2026), the location with the most reported crashes was Broadway Blvd & Wilmot Rd, with 29. That is the highest count, not proof it is the riskiest: busy junctions carry more traffic, and the data has no traffic volumes to compare crashes per vehicle.
How is this list made?
Every crash in the City of Tucson Open Data — Traffic Collisions (Tucson Police Department) has a reported point. We count crashes in a grid of about 45 m squares, then merge each busy square with its neighbours (about 135 m across) so one junction recorded at slightly different points stays one spot. Points that collect many unrelated street names are default locations, not junctions, and are left out.
Why does a junction near me not appear?
Only 20 spots are listed, and only crashes that the police reported and the city published with a location are counted. Recent weeks can still be missing while reports are processed.
How current is it?
The tally covers 292 days, 1 Jan 2026 – 19 Oct 2026, and grows each day up to a full year. The source itself is refreshed once a day on this site.
