based on the most likely estimates of congestion costs, these ranges should be used
to re
ect potential errors in estimation.

hourly earnings for determining the value of travel time
savings are shown in Table

shows average costs of travel time for US metropolitan areas, as well
as nationwide. These estimates are based on the average wage in the region, and
they are adjusted by the cost to trucks of delayed delivery of goods
