2011 Congestion Scans
As part of the CMAP Congestion Management Process, staff has created new 2011 congestion scans for expressway segments in northeastern Illinois. Congestion scans show average speed by milepost by time of day for the freeway segment. The congestion scan is a visual display of when and where, on average, a driver will experience lower speeds along a freeway segment.
