SIDRA Intersection Two Day Workshop

This two-day SIDRA INTERSECTION workshop will be presented by Dr. Rahmi Akçelik and Mr. Mark Besley who are the developers of this popular software. It provides an interactive learning opportunity with hands-on computer experience, working together with instructors through many examples. The workshop objective is to teach participants how to effectively use SIDRA INTERSECTION for roundabout analysis, signal capacity and timing analysis and lane-based network modeling using different intersection types (roundabouts, traffic signals, two-way sign control as well as pedestrian crossings), and how to apply and interpret results from the model to solve intersection and network problems. The workshop is set for US users with examples based on the SIDRA HCM (Customary) software setup of SIDRA INTERSECTION.  The latest SIDRA INTERSECTION Version 7 incorporating the HCM 6 roundabout capacity model will be used in this workshop. The workshop is offered for new and existing users of SIDRA INTERSECTION. Workshop Details [PDF] Registration: Walt Thomas    |    Class Information: Chris Cunningham

Roundabout Design

15 PDH credits

The instructors for this course will present the key geometric principles and guidelines used to develop and design a roundabout. They will highlight the differences between older traffic circles and rotaries and new roundabout design features. They will also address the typical questions of why, where, when and how roundabouts should be considered as an appropriate intersection solution. This course includes modules on recent research on U.S. roundabout capacity, roundabout design techniques, and hands-on exercises, including sketching single-lane and multilane roundabouts in a small group. The basis for the course is NCHRP Report 672: Roundabouts: An Informational Guide, Second Edition, the latest information in the HCM 6^th Edition, other state-of-the practice research, and the collective experience of the instructors on roundabout projects and research. Upon completion of this course, participants will:

• Have a basic understanding of roundabout applications,
• Understand the guiding principles of roundabout design,
• Be able to perform basic design checks of a single-lane roundabout,
• Understand the principles of roundabout design for single-lane and multilane roundabouts,
• Be able to sketch a concept single-lane roundabout and multilane roundabout,
• Understand the nuances of roundabout design related to vertical design, pedestrian and bicycle treatments, and right-turn bypass lanes.

Unconventional Intersections Laboratory

6 PDH credits

The purpose of the follow-up laboratory is to provide attendees the chance to work through hands-on examples and apply the principles discussed at the workshop. The session will include at least one challenging surface-street example, one difficult grade-separated intersection example, and one constrained interchange example. Attendees will work together in small teams to develop potential solutions and then will discuss their potential solutions with the larger group. The laboratory should again be of interest to any planners, designers, and operations professionals who work on intersections and interchanges. Laboratory attendees should have attended the alternative intersection and interchange workshop on October 21, 2020 or at some point in the past, or should have professional experience with intersections and interchanges. Attendees will need to apply basic math to the examples and should bring a laptop to the session to make the calculations easier.
