In general, junction designs that favour higher-speed turning, weaving and merging movements by motorists tend to be hostile for cyclists. Free-flowing arrangements can be hazardous for cyclists and should be avoided.[1] Features such as large entry curvature, slip-roads and high flow roundabouts are associated with increased risk of car–cyclist collisions.[54][55] Cycling advocates argue for modifications and alternative junction types that resolve these issues such as reducing kerb radii on street corners, eliminating slip roads and replacing large roundabouts with signalized intersections.[4][56]
