Alternative Intersections Comparative Analysis

The purpose of this project is to develop a guidebook for the analysis of alternative intersection designs, to be used by consulting engineers performing comparative analysis, during the preliminary engineering phase of a project. Intersection designs supported by the Federal Highway Administration (FHWA) to be included in the proposed guidebook include the displaced left-turn intersection, the median u-turn intersection, the restricted crossing u-turn intersection, the quadrant roadway intersection, the jughandle intersection, and the modern roundabout. The proposed guidebook will be divided into three sections: an overview of the various design alternatives, including literature review and documentation of where and how they have been implemented; a synthesis of analysis guidelines for these designs, specifically examining Federal recommendations and any existing State recommendations; and a proscribed analysis methodology for conducting comparative analysis of these design alternatives in preliminary engineering. The primary artifact generated by this research will be a guidebook for consultant use in the preliminary design and analysis of alternative intersections. Secondary artifacts will be conference and journal papers documenting the research findings that result from generating the guidebook. Outreach activities are consistent with the overall goal of increasing implementation of alternative intersection designs, and will take the form of general-interest presentations on the topic as available.
