2012 Expressway Atlas: Annual Average Daily Traffic on Northeastern Illinois Expressways

The 2012 Expressway Atlas provides a desktop reference of average annual daily traffic (AADT) volumes and other traffic system statistics, as well as graphics, for northeastern Illinois. The data included in the Expressway Atlas is useful as baseline data for traffic planning. The data is also useful as an input to traffic simulation models and many other expressway-system studies such as safety analysis and pavement design. This baseline data is useful for transportation system planning, but it also includes volume trends by location going back to 1984.

The 2012 Expressway Atlas is the first Expressway Atlas produced by the Chicago Metropolitan Agency for Planning (CMAP) and is also the first atlas produced for Illinois Department of Transportation (IDOT) expressways and ramps in over a decade. The previous six expressway travel atlases were produced by the Chicago Area Transportation Study (CATS) in 1965, 1972, 1984, 1990, 1995, and 2001.
