National Transportation Study 1974. Manual 1: General Information.

This manual is the first of two to be developed by the Department of Transportation to assist in conducting the 1974 National Transportation Study. This second in the series of biennial studies has been designed to build upon the data base and organizational framework established for the 1972 National Transportation Study as well as to develop information and analysis for both the National Airport System Plan and the National Highway Needs Study. In addition, the study has been designed to address critical transportation issues regarding all modes of transportation. The purpose of the 1974 study is to report the state of the nation's transportation system both current and as projected in the future and to recommend programs and policies for improvement. This manual provides general information to State and local government participants regarding the study. Part A describes the information requests to be made of the States and Part B describes the work program requested of each State for completing the 1974 study. A subsequent study will contain more detailed information and coding forms. (Author/MF)
