Note that the functional classification of roadways is the jurisdiction of the Illinois Department of Transportation and is subject to change. Data are derived from the US Geological Survey 1:100,000 Digital Line Graph files, transportation layer, 1980-1986. Publication dates of the USGS maps used as sources range from 1980 to 1986. Major highways were updated as of 1993. The maximum estimated error in horizontal position based on National Map Accuracy Standards is 167 feet. Attributes include up to three highway route numbers. Purpose: In a natural resources context, highways and roads are primarily used as a cartographic element on maps for spatial reference. They are also used for analyses that require, for example, a buffer area between roads and natural features. These data are appropriate for use in local and regional thematic analysis. They are not appropriate as a geodetic or engineering base.

Pseudo nodes (nodes between arcs with common attribute values across all non-system attribute fields) may exist on some arcs. Completeness_Report: No statement of completeness was provided with the original USGS DLG data. Visual inspection and use suggests that coverage is comprehensive but reflective of the date of source map publication date. This date varies across the state. All interstates and toll roads contained in USGS 1:100,000 DLG files are included. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Accuracy is equal to that of 1:100,000 analog maps based on USGS National Map Accuracy Standards.
