Cyclist Information

How do roundabouts keep cyclists spinning?

Bicycle facilities are typically included in all of our roundabout planning and design. Normally we include facilities for the novice or recreational bicyclist which provides a means to traverse the roundabout without encountering the adjacent motor vehicle traffic.These separated bicycle facilities cross the exits and entries at least one car length from the edge of the circulatory roadway lane, adjacent to the pedestrian crossings. Speed is a fundamental risk factor in the safety of bicyclists and pedestrians. Typical bicyclist speeds are in the range of 12 to 15 mph, and designs that constrain the speeds of vehicles traversing the roundabout to similar values will minimize the relative speeds and thereby improve safety. Design features that slow traffic such as tightening entry curvature and entry width, and radial alignment of the legs of a roundabout, such as with the urban compact design, are considered safe treatments for bicyclists.
