For 57 years, the Eno Foundation published a quarterly academic journal, called Traffic Quarterly from 1947-1981 and Transportation Quarterly from 1982-2003. Originally envisioned as being “devoted exclusively to the improvement of highway traffic,” the scope of the publication was later expanded to this:
“To help improve transportation in all its aspects through the conduct and encouragement of appropriate research and educational activities, and through the publication and distribution of information pertaining to transportation planning, design, operation, and regulation.” 
In cooperation with HathiTrust, a consortium of research university libraries led by the University of Michigan, back issues of TQ have now been made available to the public over the Internet for the first time.
