Volume-to-Capacity Ratios

Congestion also can be measured by a volume-to-capacity ratio (V/C Ratio). For the purposes of congestion calculations in this regional analysis, congestion levels are defined as:

  • V/C Ratio greater than 1.0 = Severe Congestion
  • V/C Ratio of 0.75 to 1.0 = Heavy Congestion
  • V/C Ratio of 0.5 to 0.74 = Moderate Congestion
  • V/C Ratio of less than 0.5 = Low or No Congestion
