jDefined as the ratio of peak-period travel time to free-flow travel time; used as a measure of congestion. A value of 1.35, for example, indicates that a 20-minute free-flow trip takes 27 minutes in the peak hour. Source: Schrank and Lomax, The 2007 Urban Mobility Report, Texas Transportation Institute.
