HC Deb 17 March 1927 vol 203 c2219W
Sir H. BRITTAIN

asked the Minister of Transport how many points there are in the Metropolitan area where the gyratory system of traffic is operating; and whether any point of this system has been tried and found ineffective, and, if so, which?

Colonel ASHLEY

The gyratory system of traffic, as distinguished from "one-way" streets such as the Haymarket, Long Acre, etc., is in operation at seven places, namely: Parliament Square, Hyde Park Corner, Trafalgar Square, Piccadilly Circus, Marble. Arch, Knightsbridge and Sloane Square. With regard to the last two, the system has only recently been put into experimental operation and I am awaiting reports on its operation from the Commissioner of Police and the London Traffic Committee. So far as the other five are concerned, all the information available tends to show that the systems have been effective.
