Transportation Economics in the 21st Century - Infrastructure Shapefiles

This page contains infrastructure shapefiles collected or created under the Transportation Economics in the 21st Century Project with the objective of improving access to data sets and facilitating research. This project supports research on three central issues in transportation economics: the impact of the transportation sector on the economy, new transportation technologies and initiatives such as automation and ride-sharing, and the role of transportation in contributing to household welfare. The data related to this project has been organized in several mayor categories which can be accessed here.

This project is supported by the U.S. Department of Transportation through an inter-agency agreement with the National Science Foundation, which has extended a grant to the NBER.
