Chicago's High Crash Corridors: An Interactive Map

Chicago's Vision Zero initiative designated its High Crash Corridors by analyzing reported crash data to find the streets with the highest concentrations of severe crashes — those causing serious injury or death — with particular attention to people walking and biking. The city uses this network to focus street-safety investments where they can prevent the most harm.

• High traffic volume: the busiest arterials expose more drivers, pedestrians, and cyclists to conflict points.
• Wide, fast design: streets built to move traffic quickly raise the severity of the crashes that do occur.
• Complex junctions: multi-street intersections create more potential collision paths and driver confusion.
• Mixed use: corridors combining retail, transit stops, and dense pedestrian activity see more vulnerable-road-user crashes.

• City of Chicago / Chicago Department of Transportation — Vision Zero Chicago High Crash Corridors Framework Plan (the official designation of the corridors shown).
• Corridor names reflect the streets identified in that plan; marker coordinates are approximate locators placed along each named street.
• This map does not assign crash counts or rankings to individual corridors — no official ranked list of intersections is published, so none is implied here.
