§ Sir Clive Bossomasked the Minister of Transport what arrangements are being made by her Department to study the 118W benefits resulting from the installation of lighting on the Hendon Way section of the M1 motorway and on the section of the M4 motorway leading to London Airport.
§ Mr. CarmichaelData are being collected with a view to assessing the benefits of both installations. Reliable comparisons may however be difficult to make. The Hendon Urban Motorway was lit right from the start. As for M4 to London Airport other changed factors such as the installation of crash barriers and the introduction of the breathalyser tests may make it difficult to isolate the effect of the lighting installation.
