HC Deb 09 May 1956 vol 552 c106W
57. Mr. Russell

asked the Minister of Transport and Civil Aviation whether the traffic lights recently installed at the cross roads on A5 in Elstree are vehicle-operated.

Mr. Molson

No. A short trial is being made with a traffic light installation of the fixed time type. This is designed to determine whether control of this difficult intersection can best be effected by a policeman or by a traffic light installation, whether of the fixed time or vehicle-actuated type.
