NOTES: Labor productivity for transportation
measures quality-adjusted ton- and passenger-miles per hour. Quality adjustment corrects for differences
in services and handling, e.g., the difference between flying first class and
coach or differences in the handling requirements and revenue generation of
high- and low-value commodities.
Labor productivity for transportation is calculated by dividing
an index of output by an index of employee hours. The transportation output
index is a weighted average of output indexes of railroad, trucking, and air
transportation. The shares of each
mode in total transportation value added (Gross Domestic Product) are used as
annual weighting factors. The index of transportation employee hours is
computed by weighting the employee hour indexes of each mode by its share in
total transportation employees. The
modal output and employee hour indexes were initially estimated by the Bureau
of Labor Statistics using 1987 as the base year.
