摘要

The study presents estimates of the Texas transportation bill from 1970 through 1982 and forecasts of the transportation bill from 1983 to 2005. The transportation bill is all expenditures for transportation by the private sector in Texas. The historical data were divided into passenger and freight expenditures and subdivided by transportation mode to establish the relationships between modes and between each mode and the total transportation bill. Mathematical equations were developed from the historical data and utilized to forecast future trends in the transportation bill. Transportation is forecasted to play a vital role in the Texas economy, constituting approximately one-quarter of the Gross Texas Product through 2005.
