Transportation Investment and GDP, Some Concepts, Data, and Analysis

Transportation investment consists of purchases of transportation fixed assets with a service life of more than one year and changes in inventories. Transportation fixed assets include transportation infrastructure, rolling stocks, and other equipment that are used in the provision of transportation services. Transportation investment, by implementing new technology, establishing continuity of routes and eliminating bottlenecks, and by improving the coverage and accessibility of the transportation network, helps augment the capacity and improve the efficiency of the transportation industry. Hence, statistics on transportation investment indicate the potential capacity and efficiency of transportation in future years. This report provides statistics on capital investment by sector (government, private business, and households), asset type (infrastructure, rolling stock, and other equipment used by transportation industries), and by mode of transportation (air, highway, water, mass transit, railroad, and pipelines). The investment dataset represents transportation investment before deducting depreciation of the existing capital; and this data is presented as a percentage of gross domestic product (GDP), and wherever useful, as a percentage of total gross fixed capital formation. The report also provides a review of the literature that examines the linkage between transportation investment and economic performance, a survey of similar statistical works undertaken by other U.S. government agencies and agencies of foreign countries, a discussion of data sources and procedures used to develop the dataset, and a descriptive analysis of transportation investment in relation to GDP.
