Roundabout Geometric Design

COURSE PROVIDER: Gilbert Gedeon, P.E.
Roundabout Geometric Design
Course Highlights

This online engineering PDH interactive presentation provides guidance on the most important design aspects and elements of different types of roundabouts.

Roundabout design involves trade-offs among safety, operations, and accommodating large vehicles. Some roundabout features are uniform, while others vary depending on the location and size of the roundabout. Roundabout design is an iterative process, in which small changes in geometry can result in substantial changes to operational and safety performance. This presentation will detail design considerations specific to multilane roundabouts, rural roundabouts, and mini roundabouts.

This 2 PDH online interactive presentation is intended primarily to traffic engineers, transportation planners, managers, and other technical professionals who are involved in the geometric design of roundabouts.

Learning Objectives

This PE continuing education interactive presentation is intended to provide you with the following specific knowledge and skills:

  • Familiarizing with the general design principles of roundabouts

  • Gaining an overview on double-lane roundabouts
  • Familiarizing with rural roundabouts
  • Learning about the concept of mini roundabouts
