§ Mr. George Cunningham
asked the Secretary of State for the Environment whether the Traffic and Road Research Laboratory has yet concluded its studies on the most effective design of high capacity traffic circles, and, if so, when the results will be available.
§ Mr. Mulley
Studies of roundabouts are continuing. The results of a series of experiments will be published shortly in the Transport and Road Research Laboratory's Annual Report 1973. The research findings will be incorporated in a technical memorandum from my Department, which will be available within a few months.
