INCIDENT SURVEILLANCE AND CONTROL ON CHICAGO-AREA FREEWAYS

Since 1961, Illinois has had considerable operational experience with surveillance and control of incidents occurring on Chicago-area expressways. In that year, the Illinois radio communications center was joined by two new units, the Emergency Traffic Patrol and the Expressway Surveillance Project, whose duties are to handle expressway incidents and increase expressway efficiency and safety by means of electronic traffic aids. The initiation and subsequent expansion of these three units recognized that urban freeways did not operate by themselves and that attention to continual maintenance and operational responsibilities was needed. This report describes various portions of the Illinois Department of Transportation program for reducing congestion, improving flow, increasing safety, expediting emergency responses, and providing motorist information. The considerable operational experience and refinements to date, as related to handling Chicago-area freeway incidents, are reflected in the contents.
