Strategies for Effective Roundabout Approach Speed Reduction

Summary:

Using existing research and survey results, this project developed a new resource to enable Minnesota local road engineers to select appropriate speed reduction measures for roundabouts. Further research is needed to determine the relative effectiveness of different measures alone and in combination.
