Nottingham city council has for the last 20 years has been creating stop start traffic, I. e, roundabout with traffic lights, traffic lights that turn to red for no reason, narrowing of the roadsystem. These will only add to pollution. One area in Nottingham centre was a simple traffic island, it was taken out, now you have to go through 5 sets of traffic lights with a half mile diversion. They wonder why we have pollution .
