Title: An Introduction to FHWA’s Quadrant Roadway Intersection Informational Guide
Date and Time: Thursday, April 9, 2020; 2:00 – 4:00 PM ET
Description: Alternative intersections and interchanges offer the potential to improve safety and reduce delay at a lower cost and with fewer impacts than traditional solutions. In 2014, the Federal Highway Administration published informational guides for four innovative designs: the Median U-Turn (MUT), Displaced Left Turn (DLT), Restricted Crossing U-Turn (RCUT), and Diverging Diamond Interchange (DDI). Recently, a fifth guide has been developed to provide information on the Quadrant Roadway Intersection (QRI).
The QRI concept uses a roadway in one intersection quadrant and three coordinated, signalized intersections to eliminate direct left turns at the main juncture. This allows a reduction in signal phases to improve intersection safety, capacity, and efficiencies. In addition to vehicular operational and safety improvements, the QRI has many multimodal benefits, including shorter and safer crossings for pedestrians and bicycles.
FHWA is pleased to offer this webinar to all Federal, State, Municipal, and Consultant transportation practitioners responsible for or interested in providing innovative solutions at intersections in need of operational, safety, and/or multimodal improvements. The webinar presentation will introduce the QRI Guide and review the information presented in the guide, focusing on intersection operations, safety, various geometric forms, and planning and design criteria to consider when evaluating the QRI as a potential intersection improvement alternative. The presentation will also include information provided from several DOTs that have constructed a QRI in recent years. Certificates of completion for professional development hours (PDHs) will be provided upon request.
Presenters: Jeff Shaw, FWHA Office of Safety Technologies, Guide Technical Manager; Jonathan Reid, Arcadis, Lead Author; Joseph E. Hummer, NCDOT State Traffic Management Engineer; and representatives from State DOTs having implemented the QRI.
