Since 2008, VDOT has required that roundabouts must be considered as an option for intersection control. Their ability to completely eliminate crossing conflict points and reduce crash types that lead to the severest injuries, such as t-bone and right angle collisions, make them a powerful tool in the traffic engineer’s toolbox.
Join instructors Alek Pochowski, AICP, PE and Pete Jenior, PE PTOE in a free,half-hour introductory webinar of their upcoming intermediate roundabouts workshops. The webinar answers general questions about why, where, when and how roundabouts should be considered and provides visual examples of well-designed intersections and roundabout traffic analysis. It provides a quick summary of roundabout design principles such as determining the appropriate number of lanes, strategies for providing speed control and accommodating oversized vehicles, establishing appropriate path alignment and providing appropriate sight distance.
Intended for staff responsible for roundabout or roadway design and their supervisors at both state and local agencies, the in-person workshops will be held in two parts on October 1 and 2. Attendance at both sessions is encouraged.
Part 1, a pre-requisite for Part 2, will examine the differences between older traffic circles and new roundabout design features. Special design elements, such as truck accommodations, bike and pedestrian access, and drainage issues will also be addressed. The session provides participants with the opportunity to design and sketch a single-lane roundabout.
Part 2 will involve interactive discussions on overcoming the unique aspects of roundabout project delivery, and performing roundabout design checks and peer reviews. Part 2 focuses on the special considerations of multi-lane roundabout design, and provides small-group opportunities to sketch a multi-lane roundabout.
Upon completion ofboth workshops, participants will have a fundamental knowledge of roundabout design principles as well as the ability to evaluate when roundabouts should and should not be recommended.
Alek Pochowski, AICP, PEis a senior engineer/planner at Kittelson & Associates, Inc. in Washington, D.C. He is a national expert on the planning, evaluation, and design of roundabouts. Alek has worked on hundreds of roundabout projects across the United States and Canada, and is the principal investigator of NCHRP Synthesis Topic 46-02: Roundabout Design, Operations, and Safety Practices. Alek is a member of the TRB Committee on Roundabouts (ANB75), and has assisted in the efforts to update several statewide roundabout guides.
Pete Jenior, PE, PTOEis a senior engineer with Kittelson & Associates, Inc. in Baltimore, Maryland. He has designed, analyzed, or peer-reviewed roundabout concepts for over 75 intersections in nine states and developed signal timing plans for over 125 intersections. Pete is a member of TRB’s Geometric Design Committee, and has taught short courses on applied roundabout design and performance-based design. Pete has also served as a lead researcher for NCHRP Report 772 Evaluation of the Performance of Roundabout Corridors, developed guidelines for accessibility treatments at roundabouts as part of NCHRP Project 3-78a and 3-78b, and developed four alternative intersection guidebooks for FHWA.
