Estimating the Economic Impacts of Disruptions to Intermodal Freight Systems Traffic
The goal of this work is to develop and apply a methodology to identify and estimate the economic impacts due to disruption of goods movement. The developed model is based on state of the art economic concepts that will allow the quantification of system wide impacts at the regional level. This advanced research contributes to the NEXTRANS theme of vehicle-infrastructure interactions (Pillar 2) and in integration of various modes and methods. The developed research is beneficial to government agencies such as departments of transportation (DOTs) and metropolitan transportation organizations (MPOs). A case study is included of the 2008 Northwestern Indiana highway closures due to floods. Findings: (1) There are limited secondary data sources appropriate for freight transportation modeling and analysis. (2) The best available data source for freight transportation modeling and analysis, the Freight Analysis Framework version 3, can be used for regional freight modeling under a set of assumptions developed in this project in order to overcome limitations associated to data aggregation. (3) The framework presented in this paper can be used as a good approximation for the analysis of economic impacts due to freight disruptions. Recommendations: (1) Public agencies must improve the way in which secondary data for freight modeling and analysis is presented to the researchers and general public. (2) Availability of more data will improve the calibration of the model and, hence, its accuracy. (3) Regional planning agencies need to develop freight plans that integrate appropriate data sources and models.
