EAC’s Position on Roundabouts and Active Transportation August, 2013 The Ecology Action Centre has noted an increasing trend to use roundabouts to improve intersections in the province of Nova Scotia. Through our research we have learned that roundabouts can be a great method to improve traffic flow and reduce traffic collisions. Properly designed roundabouts can reduce the speed of traffic going through intersections, reduce lanes of traffic, and bring an element of beauty to an urban street scape.
