HC Deb 20 July 1977 vol 935 cc570-1W
67. Mrs. Joyce Butler

asked the Secretary of State for Transport when he expects to evaluate the success, or otherwise, of the 12 months' experiment in the use of speed control humps; and if he will make a statement.

Mr. Horam

A series of experiments by the Transport and Road Research Laboratory on the use of speed control humps in residential areas is continuing until the spring of 1978, and full results should be available later that year. Preliminary results from the experiments show desirable reductions in traffic speed, volume and noise.
