NOTES: Capital stock is a commonly used economic measure of the capacity of the transportation system. It combines the capabilities of modes, components, and owners into a single measure of capacity in dollar value. This measure takes into account both the quantity of each component (through initial investment) and its condition (through depreciation and retirments). Data include only privately owned capital stock unless otherwise noted. Capital stock data are reported after deducting depreciation. Consumer motor vehicles are considered consumer durable goods. In-house transportation includes transportation services provided within a firm whose main business is not transportation. For example, grocery companies often use their own truck fleets to move goods from their warehouses to their retail outlets. Other publicly owned transportation includes publicly owned airway, waterway, and transit structures but does not include associated equipment. Other privately owned transportation includes sightseeing, couriers and messengers, and transportation support activities, such as freight transportation brokers. Data may not add to total because of independent rounding.
