Chicago Red Light Camera Violations by Intersection and Date

Chicago's Red Light Camera Program records daily violation volumes at each camera location from July 1, 2014 onward, excluding the most recent 14 days. The dataset includes all potential violations captured by the system and reviewed by contractors, regardless of whether a citation was ultimately issued. Columns suggest detailed geospatial and administrative data for each recorded event.

Use Cases

• Analyzing temporal trends in violations using VIOLATION DATE and CAMERA ID.
• Correlating violation rates with community characteristics using Community Areas and Census Tracts.
• Assessing enforcement coverage across political boundaries using Wards and Historical Wards 2003-2015.

Strengths

• Provides a long-term record of violations starting July 1, 2014.
