Signs direct traffic entering the roundabout to slow down and give the right of way to drivers already in it. Roundabouts can calm traffic in addition to providing a more steady traffic flow than conventional intersections.
SHARED LANES - Roadway lanes where bicycles and motor vehicles share the same lane.
SHARROW - A “sharrow” or shared-lane marking is a pavement marking symbol to assist bicyclists with lateral positioning to indicate more appropriate positioning away from the curb or parked vehicles.
