摘要：	The state of the nations infrastructure is the subject of widespread discussion and comment because it is thought to include many deteriorating and unsafe bridges. And ever since the terrorist attacks of 9/11, there has been increasing concern over the extent to which an attack on infrastructure could cause serious economic disruption. This research develops a model by which the economic consequences of an attack on any major element of the highway network can be analyzed. We do this by adding a freight network to a national multiregional economic impact model and making freight traffic flows endogenous. We base our approach on the National Interstate Economic Model (NIEMO) and refer to the elaboration as TransNIEMO (Transportation network and the National Interstate Economic Model). The new model enables us to study the state-specific and industry-specific economic impacts of any significant changes in the nature of highway freight movements. We tested the model for selected freight movements in and out of California. The results are entirely plausible and encourage us to elaborate and test the model for hypothetical disruptions of freight traffic throughout the U.S.
