This goal was accomplished through an evaluation of the results of methods already in use. Improved forecasting techniques were recommended, and a manual on forecasting methodology was prepared. The report is intended to serve as a guide to those who find it necessary to forecast the demand for highways. Chapter 1, the introduction, deals in general with such matters as economics and the allocation of resources, forecasting methods, and analysis of forecasts. Chapter 2 is a case-study analysis of national, State, and local area forecasts of population. Next comes a similar analysis of national, State, and local forecasts of motor vehicle registrations. Traffic and travel forecasts are similarly dealt with in Chapter 4. Chapter 5 discusses two aspects of the problems mentioned in the preceding analysis. The first discussed is the problem of accuracy, while the second is the relationship of governmental organization and cooperation to future forecasting activities. (Author) 收起
