The objectives of our research in transportation economics and related areas revolve around (a) gaining a better understanding of socioeconomic impacts of congestion and various congestion-mitigating strategies such as congestion pricing, road space rationing and tradable mobility credits, (b) designing efficient and practical congestion-mitigating strategies that are market-based and more acceptable to the public; (c) investigating new alternatives for transportation financing via, e.g.., public-private partnerships, and (d) developing methodologies to evaluate and prioritize multimodal transportation projects.
