Ajax Transportation Master Plan Update - Town of Ajax

Town of AjaxTransportation Master Plan UpdateFinal Report4.2 Traffic ControlThe Town of Ajax has been on the leading edge of implementing roundabouts as analternative to all-way stop control at intersections. A roundabout is a circular intersectionwhere traffic flows in one direction around a centre island where the approaches are yieldcontrolled and the right-of-way is given to circulating vehicles. Roundabouts reduce thenumber of conflict points at the intersection thereby increasing safety performance.Roundabouts are also efficient, with higher capacities and reduced vehicle delays whencompared to all-way stops and signalized intersections.There are currently eight roundabouts on Type ‘C’ designated arterials such as KerrisonDrive, Pickering Beach Road, and Williamson Drive, and three roundabouts on collector andlocal roads within residential neighbourhoods. The locations of these existing roundaboutsare summarized below and shown in Exhibit 4.• Kerrison Drive at Alexander's Crossing and Turnerbury Avenue• Pickering Beach Road at Dreyer Drive and Beachview Street• Pickering Beach Road at Foord Road and Rollo Drive• Ryder Crescent at Stokes Drive and Boyd Crescent• Seggar Avenue at Goodhart Crescent• Seggar Avenue at Sabbe Avenue and Westacott Crescent• Williamson Drive at Bellinger Drive• Williamson Drive at Gillett Drive• Williamson Drive at Middlecote Drive• Williamson Drive at Seward Drive and Warner Drive• Williamson Drive at Thackery DriveTraffic signals within the Town are under the jurisdiction of the Town or the Region ofDurham.
