Why do rural roundabouts have sidewalks?

In rural areas, drivers are normally able to pass pedestrians who are lawfully walking along the roadway or shoulder. However, the design of roundabouts omits shoulders and prevents drivers from passing in order to ensure safe operating speeds. In this constrained geometry, drivers would be unable to pass any pedestrians who were walking within the roundabout. Therefore, even in rural areas, roundabouts typically feature separated sidewalks and crosswalks to ensure safe and efficient operations for drivers and pedestrians.
