Highway Practice in the United States of America

This bulletin has been prepared by the staff of the Public Roads Administration for the use of foreign engineers who come to the United States from all over the world to study and observe highway practice as it has developed in this country, and for other students of highway subjects. The bulletin is divided into four major parts, which report on highway history, administration, and finance; systems and standards; location and design; and construction and maintenance

Highway Statistics Summary to 1945

This pamphlet presents, in convenient form, historical information of general interest on the subjects of motor fuel, motor vehicles, highway-user taxation, highway finance, and mileage. The text in each section has been restricted to a definition of terms and to a brief discussion of the information presented, since the tabulated data and analyses are in large part self-explanatory. The data were compiled and consolidated by the Public Roads Administration but much of the credit for the information must go to State officials. They have been very cooperative in supplying information concerning highways and their use. The statistics presented herein were derived principally from existing reports or tabulations, with discrepancies or inconsistencies in early records eliminated wherever reconciliations were possible. In a few instances additional information was found, the significance of which warranted revision of previously published, data. Each series has been carried back as many years as the data warrant, but the periods vary. It was impracticable to compile motor-fuel consumption data by States earlier than 1925, or national totals prior to 1919, but it was possible to create a motor-vehicle registration series, by States, beginning with 1900. Similarly, complete State highway finance data were available only for years beginning with 1914, although it was possible to obtain information on State debt for highways from 1890. This pamphlet provides background for the annual series begun with the publication of Highway Statistics, 1945
