It is not the low speed which makes urban driving so maddening. It is the herky-jerky stop-and-go nature of urban traffic. The Modern Roundabout provides the opportunity for a low-speed but continuous flow.
What is a Modern Roundabout?See also RoundaboutsUSA
A Modern Roundabout is a type of circular intersection that has been successfully implemented in Europe and Australia, and more recently in the USA. Despite the tens of thousands of roundabouts in operation around the world, there are only a few in Canada. Until recently, roundabouts have been slow to gain support in this country. The lack of acceptance can generally be attributed to the negative experience with traffic circles or rotaries built in the earlier half of the twentieth century. Safety and operational problems caused these traffic circles to fall out of favor by the 1950's. However, substantial progress has been achieved in the subsequent design of circular intersections, and a Modern Roundabout should not be confused with the traffic circles of the past.
