This page is a one-stop reference for transportation P3 resources. While P3 research often spans across different project types much of the fundamental concepts are transferrable.

This page will be updated as new research is made available.

The Eno Center for Transportation has been involved in the P3 space since with the Eno P3 Working Group (now renamed the Transportation Finance Working Group), formed in 2012 and co-chaired by former Secretaries of Transportation Norman Mineta and Mary Peters. This Working Group has been made possible by generous funding from the Surdna Foundation.

While there is an abundance of P3 research about its economic benefits, the Working Group set out to look at strategies for reducing barriers to implementation while still protecting the public interest. This research effort culminated in our 2014 report, Partnership Financing: Improving Transportation Infrastructure Through Public Private Partnerships.

Following the report, the Working Group taking the lessons learned from the research and using it to help local governments across the U.S. learn more about the P3 development process. This is being carried out through our P3 Technical Assistance Awards, geared towards educating the public sector about P3s.
