The Intersection Decision Guide aids in choosing among alternatives. It serves as documentation of an assignment carried out by a seven-member Technical Working Group to produce a procedure to determine corrective measures for intersections. Specifically, this Guide prescribes a method or model to be used by INDOT in decision-making relative to choice of basic intersection form, including forms common and uncommon to Indiana. The latter types are typically referenced as “alternative” or “innovative” intersections, and for instance include median U-turn, roundabout, displaced left-turn and other designs.
