Questions
Dangerous intersections — FAQ
What is the most dangerous intersection in Seattle?
In the official records we hold (20 Apr 2026 – 5 Oct 2026), the location with the most reported crashes was 5th Ave & Olive Way, with 30. 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 Seattle Open Data — SDOT Collisions (Seattle Police / SDOT) 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 163 days, 20 Apr 2026 – 5 Oct 2026, and grows each day up to a full year. The source itself is refreshed once a day on this site.
