Methodology for Measuring Output, Value Added, and Employment Impacts of State Highway and Bridge Construction Projects

For planning and policy purposes, state departments of transportation (DOTs) need to measure the economic impacts of highway projects. This paper presents a methodology to measure the output, value added, and employment impacts of specific types of highway and bridge improvement. Data from Kansas is used to illustrate the methodology. An 11-step procedure is described for adjusting the Kansas IMPLAN input-output model so that it can measure economic impacts for specific types of highway and bridge improvements. Data from a study of the Kansas Comprehensive Transportation Program, which included expenditure of $5.24 billion on state highway system projects, is used to demonstrate the calculation of output, value added, and employment impacts for five specific categories of highway and bridge improvements. The methodology presented in this paper can be used by state DOTs in their own planning efforts as well as to advise policymakers regarding the economic impacts of alternative highway programs.
