    Video Conference (designated rooms at DOT sites)


REGISTRATION DEADLINE: Wednesday, February 28, 2018


Roundabouts have been growing in use across the United States and are becoming a common intersection alternative for roadway projects. An understanding of associated issues is necessary for those who analyze, design and build roundabouts. This presentation will give an overview on the history of roundabouts and the most recent applications. It will include an overview on types of roundabouts and associated capacities of single and multi-lane installations. Design considerations will include design speed, sizing, truck accommodations, pedestrian and bike considerations, right-of-way impacts, signing and pavement markings. Design software options will also be covered. The presenter will give examples of projects he has designed over the past 17 years. Based on the feedback on this presentation, a future specific roundabout design presentation may be considered.
