Combination Truck Hours of Delay

Combination truck hours of delay were estimated on an hourly basis by determining the difference between delay threshold travel time and actual travel time along a facility. Delay threshold travel time/speed is considered the additional travel time experienced by a motorist beyond what would be experienced under uncongested conditions. The definition of uncongested conditions was defined as LOS B.

In 2019, the combination truck daily hours of delay decreased by 5% from 2018 to about 16,500 hours.
