§ Mr. Don FosterTo 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. JamiesonThe 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.
