HC Deb 28 July 1989 vol 157 c1099W
Sir Barney Hayhoe

To ask the Secretary of State for Transport what is his best estimate of the likely average traffic speed in 10, 20 and 30 years' time on the basis of the information and assumptions included in "Transport in London".

Mr. Atkins

I would not expect average traffic speeds in London as a whole to change substantially.
