MR. A. J. H. CLAYTON, B.Sc. (Eng.), Assoc.M.Inst.C.E., said he was a visitor who had
specialised in one aspect of the problem which was being discussed, viz., that of road traffic. The road traffic problem suffered because everybody thought he knew something about it. Road traffic control however, was a branch of road engineering and he feared that even road engineers did not study it as much as they should, yet it was particularly important in towns where large volumes of traffic had to be handled.
