A roundabout, a rotary and a traffic circle are types of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction. [1][2]

A roundabout is a circular intersection design where traffic travels at low speed around a central island and entering traffic must yield to circulating traffic.

Roundabouts are an effective option for managing speed and transitioning traffic from high-speed to low-speed environments, such as freeway interchange ramp terminals, and rural intersections along high-speed roads.

The process of designing roundabouts, more so than other forms of intersections, requires a considerable amount of iteration among geometric layout, operational analysis, and safety evaluation.

Oct 22, 2020 · A roundabout is an uncontrolled intersection or an intersection controlled by road signs where traffic moves counterclockwise around a central island. Access to the roundabout is usually controlled by YIELD signs that may be duplicated with additional yield line …

Feb 12, 2018 · A roundabout is a form of circular intersection in which traffic travels counterclockwise around a central island and in which entering traffic must yield to circulating traffic.

2009 Edition Chapter 3C. Roundabout Markings Section 3C.01 General . Support: 01 A roundabout (see definition in Section 1A.13) is a specific type of circular intersection designed to control speeds and having specific traffic control features.. Guidance: 02 Pavement markings and signing for a roundabout should be integrally designed to correspond to the geometric design …

Learn about roundabouts, including how to travel through them as a pedestrian, cyclist or driver. What is a roundabout? A modern roundabout is a circular intersection where drivers travel counterclockwise around a center island. There are not traffic …

summarizes the characteristics of roundabouts. Section 2 presents benefits of roundabout intersections compared to traditional signalized and/or stop-controlled intersections. Sections 3-6 provide an overview of user, location, operational and design considerations respectively.
