Evaluating the Performance of Corridors with Roundabouts Chapter 5–Conclusions and Suggested Research Page 5-1 CHAPTER 5. CONCLUSIONS AND SUGGESTED RESEARCH Corridors of roundabouts have developed as roundabouts have become more common and more distributed across the United States; 58 corridors were identifed at the start of this project.

Evaluating the Performance of Corridors with Roundabouts Page 5-2 o An existing suburban corridor being evaluated for safety and operational improvements due to changing context and a need for pavement rehabilitation. The use of the CCD for these four examples results in roundabout control being selected for three of the corridors, and signal control being selected for the fourth.

Evaluating the Performance of Corridors with Roundabouts Chapter 5–Conclusions and Suggested Research Page 5-5 procedure were developed using data collected on signalized arterials. The applicability of these methodologies to roundabout corridors should be assessed, and models and/or user preference surveys should be conducted for any roundabout specific aspects of corridors Before/after safety analysis: Several studies have established crash modification factors (CMFs)
