1/ For 1980-1992, Interstate System based on 100 percent inventory; non-Interstate arterial and collector functional systems estimated from sample data; urban and rural local functional systems estimated assuming two through lanes. For 1993-1995, Interstate System, other freeways and expressways, and other principal arterial functional systems based on 100 percent inventory; minor arterial, urban collector, and rural major collector functional systems estimated from sample data; rural and urban local and rural minor collector functional systems estimated assuming two through lanes.
