HC Deb 24 July 1963 vol 681 c1451
43. Mr. Brockway

asked the Minister of Transport what was the number of motor accidents involving personal injury between Taplow and Langley on the A.4 during the period 9th April to 30th June, 1962, and on the A.4 and M.4 together during the same period in 1963.

Mr. Marples

There were 53 personal injury accidents on the A.4 and M.4 together from 9th April to 30th June, 1963. In the corresponding period of 1962 there were 40 accidents on the A.4 and four accidents on the length of M.4 then open to traffic.

Mr. Brockway

Will the Minister agree that one of the objects of building the M.4 was both to relieve traffic and reduce accidents on the A.4? Is he aware also that, when the M.1 came into use, the combined accidents on the M.1and the roads it relieved fell by 26 per cent.? In this case the number of accidents has risen. Is not this due to the fact that there is only a two-lane road on the M.4 as compared with a three-lane road on the M.1?

Mr. Marples

As a matter of fact, we have gone into this very carefully and the period chosen by the hon. Member is from 9th April to 30th June, 1963. Everybody agrees that that period is too short to draw any reasonable conclusion. Therefore, I think we must wait for some considerable time more before we can draw a satisfactory conclusion.
