Traffic Safety

Traffic Safety

Preventing severe crashes on our City's streets. Data analysis and policy research help CDOT address traffic safety concerns centered around the following issues: 

Vehicle Speed & Size

70% of Chicago traffic deaths involved drivers traveling at high speeds. Over half of pedestrians killed in the city are hit by an SUV or larger vehicle.

Reckless Driving

Nearly 90% of traffic deaths in Chicago involve reckless behavior by people behind the wheel.

Persistent Inequities

Chicagoans who face the greatest barriers to health, income, and personal safety are also the most likely to die in traffic crashes.

How CDOT Uses Data
