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.
