A HISTORY OF ROUNDABOUTS IN THE UNITED STATES AND FRANCE

About the turn of the century William P. Eno in the United States and Eugene Henard in France were instrumental in introducing the concept of the "rotary" or "gyratory" movement at existing circles. This article traces the history of traffic circles and right-of-way rules at intersections in the two countries. The yield-to-the-right rule caused vehicles to lock at circles and other intersections and led to the demise of the traffic circle. Following the British example, French highway engineers are now building smaller circles whose operation relies on the rule to yield to traffic in the circle, but the American highway profession remains opposed to the use of this traffic control technique.
