Each year the Ohio Department of Transportation studies and addresses Congested Locations, which are identified by calculating a roadway's volume to capacity ratio (V/C).  This calculation compares the volume of traffic with the capacity (number of lanes) of the roadway to handle it.  Roadway sections with V/C ratios greater than 1.0 are considered congested and added to the work plan and sections with V/C ratios between 0.9 and 1.0 are added if they are outside of Columbus, Cincinnati, and Cleveland.
