Vulnerability is a performance attribute that seeks to infer the impact of partial or total blockage of a pathway reflects the performance of transport network. This concept allows to analyze both of the network resilience and the costs in different scenarios for the various actors involved. This article aims to propose a methodology for analysis and measurement of costs associated with the vulnerability of freight transportation. Thus, we developed a model of road network with 10 nodes and 15 links, based on user equilibrium, in order to perform simulations of failed arcs, in addition to measuring the risks of having obstructions. The model containing costs and risk by scenario sufficient to allow the representation of the phenomenon and the decision-making performance.
