Mobility Assessment of Pedestrian and Bicycle Treatments at Complex Continuous Flow Intersections

JOURNAL OF TRANSPORTATION ENGINEERING PART A-SYSTEMS, 147(5).

By: I. Ahmed n , S. Warchol*, C. Cunningham n & N. Rouphail n 

author keywords: Continuous flow intersection; Displaced left turn; Alternative intersection; Pedestrian; Exclusive bicycle path; Stopped delay; Number of stops
TL;DR: This study evaluated the mobility performance of pedestrian-bicycle crossing alternatives at continuous flow intersections (CFIs) by comparing CFI crossing types with a standard intersecting pattern. (via Semantic Scholar)

Queue-Based Guidance for Signalization Consideration at Two and Three-Legged Intersections

TRANSPORTATION RESEARCH RECORD, 2673(10), 416–426.

By: S. Warchol n, N. Rouphail n , C. Vaughan n & B. Kearns n 

TL;DR: A data-driven method for determining the need for considering additional signalization analysis at intersections with fewer than four legs is developed, similar to the delay-based level of service D/E threshold for two-way stop-controlled intersections in HCM6 Chapter 19.

Signal Timing for Diverging Diamond Interchanges: Fundamentals, Concepts, and Recommended Applications

TRANSPORTATION RESEARCH RECORD, (2557), 1–10.

By: C. Cunningham n, B. Schroeder, S. Phillips, T. Urbanik, S. Warchol n & A. Tanaka

TL;DR: The state of the practice in DDI signal phasing with principles established in the Signal Timing Manual is documents, namely, that it uses consistent phase numbering in a logical format to describe each of the phasing concepts being considered and discussed in this paper.
