Portland State University - University Place Conference Center
1825 SW Broadway, Portland, Oregon

About the 2-Day Course

The advantages of the modern roundabout, including modified and improved design features, are again being recognized, more fully explored, and put to the test in the United States.

Join us for this interactive workshop on the development and design of the modern roundabout. The instructors from Kittelson & Associates, Inc. (KAI) have extensive experience in the field of roundabouts and will cover a wide variety of topics, including:

• Roundabout site selection and planning;
• Operational analysis steps;
• Detailed design guidelines;
• Ways to measure effectiveness.

This course draws from the latest in research and applied techniques. FHWA’s Roundabouts: An Informational Guide, and its forthcoming Second Edition (NCHRP Report 672), provides the backbone for this workshop. In addition, the instructors will incorporate their practical experience, as well as information gained from their interaction with TRB, ITE, NCUTCD, and IESNA committees. You’ll find more details about the instructors and this course on the registration web page.
