An analysis of methodologies to estimate the economic impacts of freight transportation system disruptions

Abstract

Disruptions to the freight transportation system are costly due to freight's critical relationship to economic productivity. This research will analyze the current methods of estimating the economic impacts of disruptions to the freight transportation system. A review of existing literature will be conducted with the intent of finding methods that address different types of disruptions and impacts. Due to varying economic scopes and disruptions studied, the results will likely indicate a broad range of methodologies and trends. The results will be used to better understand the different approaches taken when quantifying the economic impacts of disruptions and therefore enable more informed policy, regulation and investment.
