A recent LRRB project, “Strategies for Effective Roundabout Approach Speed Reduction,” provides the methodology to select, install, and evaluate treatments at different locations. This project had two goals:
- To analyze existing research and conduct a survey of roundabout design and installation practitioners to determine best practices;
- To develop a resource that engineers can use to identify appropriate speed reduction treatments for high-speed approaches to roundabouts.
The result was a 100+ page report. The goal of this RIC task is to synthesize this information into a more useful, quick-reference tool, possibly including one or more of the following:
- A more digestible decision tree
- One-pager quick reference
- A video
