Driving on roads in Illinois costs motorists a total of $18.3 billion per year in the form of extra vehicle operating costs (VOC) as a result of driving on roads in need of repair, lost time and fuel due to congestion-related delays, and the costs of traffic crashes in which roadway features likely were a contributing factor. The TRIP report calculates the cost to motorists of insufficient roads in the Chicago, Champaign-Urbana, Metro East, Peoria-Bloomington, Rockford and Springfield urban areas.
