Transportation investment policy faces an unprecedented critical moment especially when traditional public funding sources shrink. How to allocate the limited funding source among different modes of transportation infrastructure to maintain their quality and function is not only a challenging decision, it also requires the knowledge and understanding of the relationships between transportation infrastructure and regional economic development. This study conducts a comparative assessment investigating this relationship with a focus on a multimodal perspective. Through the comparison of the authors’ previous evaluation studies conducted at different geographic scales in the US and using different data and methodologies, the regional economic impacts of different modes of transportation infrastructures are contrasted and discussed. Although transportation infrastructure is found to have a consistent positive impact on regional development across different studies, the effects vary considerably among different modes of transportation. Issues of impact assessment and policy implications are raised and discussed.
