Abstract
This paper develops, through a simulation model, a deeper understanding of the relationship between transportation infrastructure strategy development frameworks and system performance. A strategy development framework for transportation can be characterized by the infrastructure ownership structures, cross-modal and cross-sectoral linkages, revenue sources, resource allocation decision-making processes, and geographic scales of the organizations responsible for making infrastructure investments. Taking the dimensions of a strategy development framework as inputs, the model simulates investments in an infrastructure network over time—in this paper, the national intercity roadway network of Portugal. The results demonstrate the value of using simulation models of complex transportation systems to inform the decisions of not only planners but also of stakeholders who design strategy development frameworks. Such a tool is particularly important given the ongoing reorganizations of the Portuguese transportation sector, including increasing reliance on concession agreements, highway tolls, and sub-national government participation.
