20 mph limit for urban streets to cut road deaths - The Times 16th May 2008

The speed limit on thousands of residential roads will be reduced to 20mph under government moves designed to cut road deaths by a third over the next decade. Variable limits will be introduced on main roads near schools, with digital signs ordering drivers to cut their speed to 20mph or less when pupils are arriving or departing. Cameras that detect a vehicle’s average speed will be used instead of road humps to enforce the limit in some of the new 20mph zones.
