| 摘要： | This research provides a comprehensive review and assessment of current ‘alternative intersection’ methods which successfully eliminate the left-turn phase. With increasing traffic and limited resources, the Florida Department of Transportation moves forward with a vision of optimizing intersection control through the implementation of innovative intersection designs through the Transportation Systems Management & Operations (TSM&O) program. Because of the specific interest in the integration of alternative intersection treatments within the State of Florida, this research assessed the operational benefits, challenges, evaluated the safety implications for bicycles and pedestrians through the alternative intersection methods, and quantified driver confusion opportunities, maintenance impacts, and comparative cost control measures for benefit-to-cost ratio development. The operational analysis is based on several case studies presented along with the advantages and disadvantages of each alternative. The overall analysis provided a variety of parameters that need to be considered when implementing any of these designs. These intersections can be significantly cumbersome for vehicles, bicyclists, and pedestrians to navigate without proper implementation of wayfinding signs and education of the road users. However, when applied properly, the benefits of these designs can save municipalities years of capacity and preserve the existing infrastructure for a longer period of time. These goals align with the overall goal of the FDOT TSM&O program. |
