Mini Roundabout FAQs
Roundabouts have been effective at increasing safety and efficiency of vehicle traffic. Traditional roundabout design typically requires a larger “footprint” than a traditional four-way intersection. More local agencies are implementing “mini roundabouts,” a type of roundabout characterized by a small diameter and fully traversable islands (central island and splitter islands). The focus of this implementation project will be an FAQ document that: Defines and educates local agencies on use of mini and compact roundabouts; Provides selection criteria on when to use and details regarding the center treatment; Synthesizes and provides easy navigation to technical information.
