HC Deb 17 January 1967 vol 739 cc25-6W
Mr. Geoffrey Lloyd

asked the Minister of Transport what research is in hand into methods of accelerating the dispersal of fog on motorways.

Mr. Swingler

Research to date on fog dispersal from motorways has included consideration of the wartime FIDO system, use of lasers and mechanical means. All would be prohibitively expensive, even if practicable.

The Road Research Laboratory are currently surveying the more diverse fog problems, such as frequency of occurrence, location and cost due to delay.
