§ 90. Mr. Danceasked the Minister of Transport if he will make a statement on his policy regarding the use of antidazzle and crash barriers on sections of motorways; and what further experiments are being carried out.
§ Mr. MarplesI am having a full study made in conjunction with the Road Research Laboratory of safety measures on motorway central reserves.
Experiments with the metal mesh antidazzle screen on M.1are continuing. The evidence so far of its effect on accidents is however insufficient to warrant the extension of the screen or its installation on other motorways. A further experiment making use of hessian screens to test the anti-dazzle value of central reserve planting is being conducted by my Department on M.1.
To test the value of crash barriers two nine-mile experimental lengths of double steel rail stafety fence are shortly to be installed on M.1. The Road Research Laboratory is also continuing tests of the cable type safety fence.
