There exists a large literature of transportation impacts on economic and demographic change. Prior studies have focused on single modes of transportation individually rather than integrating these modes. Yet, little work has been undertaken to study the economic and demographic impacts of intermodal transportation systems. This study fills the gap in the literature by examining intermodal passenger transportation on demographic change. Specifically, this research investigates the effects of highways and airports on population change in the minor civil divisions of Wisconsin by adopting an integrated spatial approach. The results show that overall, airport accessibility and highway improvement affect population change, but highway accessibility and airport improvement do not. However, the effects exhibit variation across rural, suburban, and urban areas. Highway improvement acts as an investment input and airport accessibility uses the locational advantage to promote rural population growth. In suburban areas, airport accessibility promotes population growth but highway accessibility acts as a facilitator of out-migration. The effects on urban population change are not statistically significant and are likely constrained to land use policies and regulations. This study have important implications to transportation planning as transportation planning practices are focusing more attention on intermodal transportation systems as a whole rather than any single mode of transportation. Intermodal transportation systems have become increasingly important for transportation performance and efficiency.
