RESEARCH into the de-icing of road surfaces by submerged electrical elements was among the projects shown to invited guests during two open days at the Road Research Laboratory at Harmondsworth last week.
The need to obtain further data on the stresses to which road surfaces arc subjected has prompted the Laboratory to devise a machine for automatically weighing vehicles in mcition. It takes the form of a pad sunk flush into the road surface, recording weights as vehicles pass over it (The Commercial Motor, May 2),
The Traffic and Safety Division of the Laboratory at Langley, Bucks, was also open to visitors. Tests shown included those on various types of safety glass, on vehicle braking under different conditions and tests on safety equipment. Records of detailed post mortern examinations on accidents, carried out in collaboration with local police forces, .provide information for the development of safer vehicles and on the causes of accidents.
Many types of equipment on show had been tested in connection with the setting up of compulsory vehicle inspection stations, some devices for this use having been designed by the staff of the Laboratory.
A Morrison Electricar milk float was also exhibited with a full-width horizontal mirror above the windscreen to give the driver full vision up to the front bumper. This has been devised to reduce the risk of accidents to small children, who are particularly prone to injury from silent electric vehicles.
