Published as NCHRP Research Report 948: BACKGROUND . New alternative intersection and interchange designs - including Diverging Diamond Interchanges (DDI), Displaced Left-Turn (DLT) or Continuous Flow Intersections (CFI), Restricted Crossing U-Turn (RCUT) intersections, Median U-Turn (MUT) intersections, Quadrant Roadway (QR) intersections ...

Research That Looks Out For Pedestrians & Bicyclists At Intersections This research project led to the development of methods for ensuring pedestrian and bicycle safety at AIIs. The resulting guidebook, NCHRP Report 948, provides transportation practitioners with ways to integrate non-motorized user-safety considerations at AIIs through ...

8,000 comments, NCHRP Research Report 948 provides a performance-based assess-ment method that can be applied in the concept or final design stages, as well as in safety audits of existing locations. A Test of "20 Questions" At the heart of NCHRP Research Report 948 is a quantitative analysis method built around 20 design flags: 20 perfor-

Alternative Intersections and Interchanges (A.I.I.s) are designs that improve operations and safety for motorized traffic by strategically adjusting the geometric features at a given location, working on the general principle of redistributing motor vehicle demand at an intersection in an attempt to limit the need to add capacity with new lanes to improve traffic flow.

How To Apply NCHRP Report 948. After conducting a literature review, surveying agencies who have implemented A.I.I.s, and holding focus group sessions to understand the experience of pedestrians and bicyclists, our research team developed a quantitative analysis method built around 20 design flags.

This webinar will provide an overview of NCHRP Report 948 and a methodology for evaluating and quantifying pedestrian and bicyclist safety at alternative intersections, as well as conventional intersections the new designs may be compared against. The "20 Design Flags" method provides a performance-based approach to evaluating design elements of existing or proposed intersection designs.

This report provides specific guidance for four common Alternative Intersections and Interchanges (A.I.I.s): Diverging Diamond Interchange (DDI), Restricted Crossing U-Turn (RCUT), Median U-Turn (MUT), and Displaced Left-Turn (DLT). ...

NCHRP Research Report 948 provides examples of forms for this process. 4. If desired, use a qualitative rating or ranking to compare alternatives based on the number of comfort-related or safety-related design flags, recognizing that these design flags are only part of the overall evaluation process. ...

The primary focus of the research is roadway functional classifications of collector and above. The approaches to evaluate pedestrian and bicycle treatments can be separate, but implementation of the treatments should be coordinated. ...

The TRB National Cooperative Highway Research Program's NCHRP Research Report 926: Guidance to Improve Pedestrian and Bicyclist Safety at Intersections provides a succinct process for selecting intersection designs and operational treatments that provide safety benefits for pedestrians and bicyclists, and the most appropriate situation for ...

Fortunately, there is a new method available in NCHRP Research Report 948 that quantifies the quality of experience for a pedestrian or bicyclist at any intersection.10 Based on focus groups, surveys, and expert opinions, the researchers developed a method that scores each crosswalk and bicyclist movement at an intersection on 20 different aspects.
