Research Idea Scope

The sustainability of the United States transportation system is threatened over the long term. An aging, congested highway focused system hinders economic prosperity yet revenues are inadequate to pay the cost of long term maintenance and operations. Meanwhile, unintended externalities caused by transportation affect a broad spectrum of human and natural environmental issues and economically disadvantaged groups are unable to share in transportation benefits available to a wider population. In the coming decade, road pricing is likely to become the next step toward creating an economically, environmentally and socially sustainable transportation system.
