• Abstract:
  This research deals with two related issues: investigation and mitigation of roundabout elements that lead to driver ; confusion, and development of a flexible criteria matrix by which the Nebraska Department of Roads (NDOR) can ; evaluate arterial intersections to identify good candidates for conversion to roundabouts. The use of modern roundabouts ; along arterial roadways is relatively new in Nebraska. The first urban arterial roundabout was opened to traffic in June of ; 2002 at the intersection of 33rd and Sheridan Blvd in the City of Lincoln. Citizens and some professionals were somewhat ; skeptical of the capability of this roundabout to improve traffic delay and safety. However, after the construction of this ; roundabout the City of Lincoln has reported reduced traffic delays and the Nebraska Department of Roads (NDOR) has ; reported a reduction in traffic accidents. The objectives of the research include: (1) identification of user issues and ; confusing elements of roundabouts via surveys and development of mitigation measures for safer usage of arterial ; roundabouts in Nebraska; and (2) development of a criteria matrix for arterial intersections that NDOR can use to check the ; candidacy of intersections for conversion to single-or multi-lane roundabouts.
