Roundabout Planning, Design and Implementation

By the end of this course, you will be able to:

• Assess where roundabouts are appropriate based on operational, safety, and site-specific conditions
• Evaluate design trade-offs to optimize safety, capacity, and long-term performance
• Apply capacity analysis methods to support roundabout planning and decision-making
• Develop practical geometric design solutions aligned with industry standards
• Identify key design, maintenance, and implementation considerations that impact real-world performance

Description

Intersection performance challenges, such as congestion, collision risk, and inefficient traffic flow, require solutions that balance safety, capacity, and long-term operational performance. While roundabouts are widely recognized as an effective alternative, their success depends on appropriate application, sound analysis, and careful design decisions.

This course provides a structured approach to evaluating, planning, and designing modern roundabouts. Day 1 focuses on planning and operational considerations, including assessing suitability, safety performance, and capacity. Day 2 builds on this foundation by addressing geometric design and the practical application of design principles in a range of conditions. Participants may register for either day individually or attend both days for a complete view of roundabout development from planning through detailed design.

Through applied examples and structured guidance, this course supports the development of practical skills that can be directly applied to intersection planning and design challenges in professional practice.
