Illinois Traffic and Pedestrian Stop Study

On July 18, 2003, Senate Bill 30 was signed into law to establish a four-year statewide study of data from traffic stops to identify racial bias. The study began on January 1, 2004 and was originally scheduled to end December 31, 2007. However, the legislature extended the data collection several times, and also expanded the study to include data on pedestrian stops. Public Act 101-0024, which took effect on June 21, 2019, eliminated the study's scheduled end date of July 1, 2019 and extended the data collection.

The Illinois Traffic and Pedestrian Stop Study System, maintained by IDOT, collects and compiles Traffic and Pedestrian Stop data from Police Agencies throughout the State of Illinois. Data is submitted by Police Agencies through an IDOT self-reporting application.

The IDOT system and application allows Police Agencies to submit Traffic and Pedestrian Stop data per individual stop or allows Police Agencies to compile required data using their own application which can then be uploaded to the IDOT system via a text file.

All Traffic and Pedestrian Stop data collected for 2024 must be submitted by February 1, 2025.

Effective January 1, 2024, the Illinois Secretary of State will begin using ‘X’ for Gender X (non-binary, etc.) on Illinois driver’s licenses. The Illinois Department of Transportation (IDOT) has decided to follow federal guidelines utilizing the Model Minimum Uniform Crash Criteria (MMUCC) and use ‘O’ (Other) for Gender X (non-binary, etc.).

Beginning January 1, 2024, law enforcement agencies submitting traffic and pedestrian stop data will use the following codes for the Gender field.

  • 1 or M for Male
  • 2 or F for Female
  • 3 or O for Gender X (Non-Binary, etc.)
  • 9 or U for Unknown

Law enforcement agencies will be required to use these codes when submitting crash reporting records to IDOT, whether it be electronically or by paper. All Third Party, XML electronic vendors and paper agencies have been notified of this change.

Police Agencies are required to be registered to utilize the system. For additional assistance Please contact Sean.T.Berberet@Illinois.gov or 217-524-1117.
