mph is not dangerous driving. Won’t lowering the speed limit cause delays to motorists?
The nature of the city’s residential roads is that due to their narrowness and dense parking it is neither safe or appropriate for vehicles to travel at speeds greater than 20mph. This is borne out by the speed surveys, carried out prior to introducing the schemes, which show that in almost all cases the existing average speed is in the range of 18-24mph on the chosen roads.
