Summary: | This webinar will present information about the analysis, design, and implementation of diverging diamond interchanges. Learn how the use of diverging diamond interchanges began in the U.S., the current status of deployments of the concepts within the U.S., cost advantages, suitable traffic and environmental conditions, tools for estimating capacity, and signal coordination. Also learn about
accommodating pedestrians, bicyclists, transit vehicles, and special design/operations requirements at diverging diamond interchanges as well as constraints and possible treatments for nearby intersections.
|
Learning Outcomes: | Participants will have the opportunity to establish a good understanding of the benefits and limitations of the diverging diamond interchange design, traffic, and environmental conditions under which it will be more cost effective for reducing congestion and improving safety. Participants will learn how CAPX (spreadsheet based software) can be used to quickly size diverging diamond interchange lane configurations, proper scope of signal timing optimization and coordinating design features for accommodating pedestrians, bicyclists, and special transit vehicles. Participants will also learn some innovative treatments for nearby congested intersections toward better use of the capacity potential of
the diverging diamond interchange concept.
