§ Mr. Remerasked the Minister of Transport how many pedestrian crossings, fitted with the ray apparatus similar to that established on the Sutton by-pass, have been placed in England; whether this apparatus is experimental; and whether he will state the results of those experiments?
§ Mr. BurginFive traffic light signal installations employing ray detector apparatus have been provided in different parts of the country. Experience with this type of apparatus has led me to the conclusion that installations of the normal type are to be preferred.
