• ThrU-Turn intersection

• Single Point Interchanges

• Roundabouts

Mini Workshop 1: Diverging Diamond Interchanges - Design Insights and Innovations

With the first few dozen DDIs constructed and operational in the U.S., there are many valuable lessons that have been learned. Expert designers will relate their project experiences on planning and designing DDIs across the United States, including some innovative variants of DDIs.

Presenters

• Gilbert Chlewicki, ATS-American

• Joel Leisch, Consultant Diverging Diamond Interchange

• Smith Siromaskul, HDR

Mini Workshop 2: Operational Analysis Tools & Techniques for Alternative Intersections

Several operational analysis tools will be highlighted, with tips and techniques demonstrated using case study examples from alternative intersection and interchange projects. The workshop will

explore the differences between several of the most popular analysis tools and explain the similarities and differences in the models.

Presenters

• Ram Jagannathan, Leidos

• Jim McCarthy, Federal Highway Administration - US 212 Safety Program Use 2010 HCM for RCUT

• Michael Armstrong for Lily Elefteriadou, University of Florida - Integrating Alternative Intersections & Interchanges into HCS 2010

• Bastian Schroeder, ITRE/NCSU - Diverging Diamond Interchanges (DDI) in the HCM

Mini Workshop 3: Overview of New FHWA Informational Guides

A “guided tour” of the new FHWA series of stand-alone Informational Guides on the following alternative intersections/interchanges: Diverging Diamond Interchange, Displaced Left Turn Intersection, Median U-Turn Intersection and Restricted Crossing U-Turn Intersection.

Presenters

Overview of New FHWA Informational Guides

• Mark Doctor, Federal Highway Administration

• Brian Ray, Kittelson

• Hermanus Steyn, Kittelson

• Andy Daleiden, Kittelson

• Pete Jenior, Kittelson

Mini Workshop 4: Managing Access & Expectation

A public outreach and involvement effort on innovative intersection projects is essential to success. Additionally, provisions for access to homes or businesses adjacent to any road project can be as controversial as the project itself, suggesting that managing access is also related to managing expectations and clearly communicating trade-offs. Recent experiences and ongoing research will provide insight on how to approach managing both access and expectations effectively.
