Arkansas

Employing Continuous Flow Intersections following a study of their efficacy and a search for candidate locations.

Background: The Arkansas highway Commission undertook a planning study to evaluate the efficacy of continuous flow intersections (CFI). CFI's essentially relocate the physical and operational aspects of approaching left turns at major intersections, in advance of the intersection and in combination with side street signal movements, respectively.

Bottleneck Project: Highway 71B (College Avenue) at Joyce Boulevard, in Fayetteville. After undergoing a consultant aided study of the efficacy of CFI's, and developing a candidate list of intersections; 35 initially, then narrowed to 20, then to 10. The "best fit" candidate was Highway 70/Highway 5, but this intersection was already well under conventional redesign and has moved forward to construction. The second "best fit" candidate was the subject one. At present there is still some necessary final design and further analysis to undergo.
