I was in Europe over the
summer and one of the things I enjoyed was driving through the roundabouts. I
love roundabouts! Or traffic circles, if you prefer (but I don’t). I believe they
are more fuel efficient, safer and a less polluting option than four-way stops
and other intersections.
The logic goes - because drivers aren’t stopping, less vehicle
emissions are produced. When a constant speed is maintained, there is no spike
in emissions due to stopping and starting. Higher fuel efficiency is therefore
attained – and in the city too! With the vehicle already running, engine noise
is rather lower than starting from a complete stop. No doubt this would be
appreciated by homeowners!
