HC Deb 02 July 2002 vol 388 cc216-7W
Mr. Don Foster

To ask the Secretary of State for Transport what research has been conducted(a) by and (b) for his Department on the effect of variable speed limits; and if he will make a statement. [66005]

Mr. Jamieson

The Transport Research Laboratory (TRL) monitored trials on the effectiveness of variable speed limits outside schools. Variable message signs were installed outside schools that reduced the speed limit typically one hour around school arrival and leaving times. The results showed very little reduction in vehicle speeds and the report concluded that as a speed reducing feature they were ineffective.
