※AASHO：全米州道路行政官協会（American Association of State Highway Officials）

Toward the end of the 1940s, the AASHO Committee on Planning and Design Policies, with the assistance of the BPR, undertook the development of generally applicable analytical techniques for performing economic analysis of highway projects. The work grew out of a survey of state highway departments on the use of economic analysis that found a definite lack of similarity in such procedures and their use (American Association of State Highway Officials, 1960).

Building on earlier work on highway economic analysis, the committee developed a manual for conducting benefit-cost analysis (American Association of State Highway Officials, 1952b). The basic tenet of the manual was "that a profit should be returned on an investment applies as well to highway projects as to general business ventures."
