Roundabouts are not good for pedestrians and bicyclists.

Roundabouts are very pedestrian friendly. The splitter islands provide a space for pedestrians in the middle of each crossing. Therefore, pedestrians only need to cross one direction of traffic at a time. The pedestrian crosswalks are set at least one full car length back from the yield line. That way, pedestrians do not have to cross in front of drivers that are looking for their gap in traffic. Experience has shown that the stopped vehicle one car length back from the yield line is more aware of pedestrians.

One special note: pedestrians should never cross to the center island in a modern roundabout.

The benefit of modern roundabouts in terms of the rate of bicycle crashes has not been as successful as the benefits to motorists and pedestrians. Some studies have found that bicycle crash rates have not been reduced. Other studies have found that bicycle crash rates may actually increase. For this reason, many new modern roundabouts include bypasses for on-street bike riders.
