Questions

Dangerous intersections — FAQ

What is the most dangerous intersection in Chicago?

In the official records we hold (29 Sep 2026 – 20 Oct 2026), the location with the most reported crashes was Near Lake Shore Dr, with 12. 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 Chicago Data Portal — Traffic Crashes (CPD) 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 22 days, 29 Sep 2026 – 20 Oct 2026, and grows each day up to a full year. The source itself is refreshed once a day on this site.
