Illinois Traffic Stop Study

IDOT is responsible for collecting and compiling the data. IDOT has developed an Internet self-reporting application for submission of the data. Agencies have two options for entering data into the IDOT data collection system.

• The agency can use the IDOT web site to enter data on individual stops.
• The agency will have the option to compile the data using their own data application. The data can be exported from this application into a text file that can then be uploaded to IDOT's website.

Agencies using their own applications are encouraged to upload their data to IDOT at least once a month.

All agencies will need to be registered in order to enter or upload data using this website. They will also need to be registered in order to download the standalone applications. In order to register, please call Julie Neposchlan at 217-524-1117.
