Traffic Maps

The Traffic maps listed below display the annual average daily traffic (AADT) on the State Primary system. The Primary system contains the roads that are marked as an Interstate, United States Route, or Illinois Route. These files are very large and may take a significant amount of time to download.

More detailed AADT counts are available on the interactive GIS application.
