The Joint Transportation Research Program (JTRP) has partnered with the Purdue Libraries to provide state-of-the-art digital production and open-access web-based dissemination tools. The largest collection is composed of over 1600 technical reports produced for projects funded by the Indiana Department of Transportation. The technical report production process and open access policy has been tremendously successful with over 1,000,000 downloads in the last 6 years and is widely regarded around the country as a best practice for producing and disseminating transportation research. This process and selected download statistics are described in a recent Transportation Research Board paper.

Purdue faculty members are highly sought after for transportation-related research by many other government agencies, associations, and the private sector. To leverage the streamlined production and dissemination processes developed by JTRP and the Purdue Libraries, the JTRP Affiliated Reports series was created to provide Purdue faculty a publication venue for technical reports funded by other sponsors. Each of the publications in this series has an acknowledgment section that recognizes their sponsor(s).
