Estimated Annual Congestion Cost per Person

(Current dollars)

  1990 cost per person 2000 cost per person Percentage change 1990-2000 Annual growth rate 1990-2000
Very large areas 388 648 67 5.3
Large areas 169 424 151 9.6
Medium areas 88 273 210 12.0
Small areas 40 115 188 11.1

Note: Very large = over 3 million population (e.g., New York-northern NJ) Large = 1 million-3 million population (e.g., Atlanta) Medium = selected areas with 500,000-1 million population (e.g., Memphis) Small = selected areas under 500,000 population (e.g., Colorado Springs) TTI estimates delay indirectly by using traffic volumes and methodology developed by the Federal Highway Administration for estimating the effects of roadway incidents. TTI estimates cost by taking into account fuel cost, value of time, and commercial vehicle operating cost.
