FORECAST OF TRUCKLOAD FREIGHT OF CLASS I MOTOR CARRIERS OF PROPERTY IN THE SOUTHWESTERN REGION TO 1990

Truckload revenue freight of Class I common and contract motor carriers of property operating in intercity service in the Southwestern Region has been forecast to 1990 using multiple regression analysis. Data were gathered on the dependent variable (truckload freight) and on thirty independent variables (economic indicators of the Southwestern Region) for the base period 1957 to 1971. Missing values from the time series data were estimated by curve fitting techniques to the known data points. Comparison of the three predictor regression equations, a Department of Transportation projection, and the closest fitting extrapolation of the truckload freight data, along with all the statistical evidence available, led to the selection of a best forecast, which is a set of four economic indicators.
