• Abstract:
  The intersection and mandatory movement lane control signs placed on intersection approaches are critical to ; safe and efficient intersection operations. Ramp, frontage road, and cross-street approaches to interchanges ; often widen at intersections to accommodate additional through or turn lanes. Currently there is ; inconsistency in conveying to drivers how they should align themselves upstream of a diamond intersection ; to maneuver for their desired turning movement as the intersection widens. These inconsistencies can result ; in drivers making incorrect lane selection, which may result in late lane changes or illegal turns. This project ; conducted state-of-the-practice surveys, focus groups, and driver surveys to develop test signs used for field ; deployment and evaluation regarding lane assignment on frontage roads and cross streets. The findings ; include evaluation of an enhanced R3-8 sign to show roadway widening on a frontage road and evaluation of ; a guide sign to indicate lane choice when approaching a freeway interchange on a cross street. The research ; provides recommendations on when to apply non-standard signing to more clearly convey lane assignment to ; drivers on approach to more atypical intersections.
