Active Transportation

Complete streets, transit, bikeway, and pedestrian planning, design, and performance measurement

Roundabouts: Balancing Safety & Mobility for All Users

The course will guide transportation practitioners through the evaluation and design aspects for roundabouts within a multimodal and complete-street context.

Topics covered include lane configuration, traffic operation evaluation, bike and pedestrian design, signing and striping, right of way, drainage, and landscaping consideration. Additionally, we will discuss planning and policy, safety, public involvement, operation, geometry, and other design components.

The instructor will explain lessons learned from past practices in a variety of jurisdictions including California, other states and other counties. Students who wish to receive an evaluation of real life practice are encouraged to attend.

Additional course detail is provided in the sections below.

  • Course Outline

    Day 1: Why Roundabouts

    • History of Roundabout
    • Definition of Roundabout
    • Benefits of Roundabout
    • Why Roundabout Is Safer
    • Roundabout Development in the US
    • FHWA & Caltrans Policies, Guidelines & References

    Day 2: Roundabout Planning Aspects

    • Reflect on Lessons Learned in Day 1
    • Roundabout Planning and Community Context
    • Roundabout Capacity Analysis Geometric Parameters

    Day 3: Roundabout Design Aspects

    • Reflect on Lessons Learned in Days 1 & 2
    • Roundabout Geometric
    • Design Design Attributes & Multi-modal Considerations
    • Final Design Process
    • Case Study
  • What you will learn

    By the end of this course, students will understand the principles and working concepts of roundabouts within contexts of policy, planning, public involvement, design and operation.

    Students will also learn about capacity analysis, crash rates, traffic calming, right of way impacts, geometric design principles, sight distance criteria, traffic operations, pedestrian and bicycle treatments, landscape, drainage as well as other system considerations.

    The class will evaluate many roundabouts implemented in the US, as well as other countries in Asia and Europe.

  • Who should attend

    This course will benefit transportation professionals who are involved in planning, feasibility study and design of roadway projects that may incorporate proposed intersection modifications and traffic calming.

    Attendees will be able to quickly assess considerations for installing roundabouts as an alternative to traditional intersection controls.

    This course is targeted to expand the knowledge of individuals with some background in evaluation and design of intersections and other mobility improvement projects, although such background is not a prerequisite for attending this training.
