Henebery, Ann. "The Rules of the Road: Then Versus Now", Eno Center for Transportation, October 6, 2015. Accessed October 9, 2017. "William P. Eno is internationally recognized as an original pioneer of traffic regulation and safety. He authored the very first Rules of the Road, which were adopted by New York City in 1909 and by London and Paris in the years following. He was dubbed the n'Father of Traffic Safety' and many of the traffic-flow innovations that we now take for granted were a result of Eno’s hard work. He is credited with designing Columbus Circle in New York City and the traffic circle surrounding the Arc de Triomphe in Paris."
