Transportation Economics in the 21st Century - Research Projects
The initiative supports projects focused on four distinct topic areas: (1) Transportation and the Economy; (2) New Transportation Technologies and Initiatives; (3) Transportation and the Human Experience; and (4) Transportation Data and Research Infrastructure.
An initial call for research proposals was broadly disseminated in October 2019. It resulted in more than 50 submissions, from which the investigators selected six projects for funding in the 2019-20 academic year. The selection process focused on the intrinsic quality and interest of the projects, and was carried out in consultation with staff members at the Department of Transportation. The funded projects, all of which relate to the Department’s current research needs, are:
Traffic in the City: The Impact of Infrastructure Improvements in the Presence of Endogenous Traffic Congestion
Investigators: Treb Allen, Dartmouth and NBER and Costas Arkolakis, Yale and NBER

A second call for proposals was disseminated in October 2020. From the 39 proposals that were received, the investigators selected five projects for funding, once again in consultation with DOT staff and focusing on topics related to the Department's research objectives. The funded projects for the 2020-21 academic year are:

Investigators: Marta Santamaria, University of Warwick and Diana Van Patten, Princeton University
A third call for proposals was disseminated in August 2021. From the 26 proposals that were received, the investigators selected nine projects for funding, once again in consultation with DOT staff and focusing on topics related to the Department's research objectives. The funded projects for the 2021-22 academic year are:
