Learn about the safety principles behind the roundabouts and the specific design practices employed to address both simple and complex issues.
Congestion and safety problems occur at intersections, with nearly 70% of all vehicular crashes and approximately 50% of pedestrian crashes in urban areas occurring at or near intersections or driveways. Our current paradigm of intersection and roadway improvements with signalization is often detrimental to businesses near the intersection and overall liveability objectives. This course will discuss how roundabouts can resolve these competing needs and the benefits of roundabouts in the overall roadway/traffic planning process. This course will also discuss the importance of roadway and roundabout design safety principles to ensure well-received and successful projects.
Learning Objectives
- You will be able to describe the benefits of roundabouts in the overall roadway/traffic planning process.
- You will be able to explain the importance of geometric design optimization.
- You will be able to identify the potential pitfalls in roundabout design.
- You will be able to recognize the correlation between operational analysis, geometric design, and multimodal safety.
