§ Mr. Ronald Atkinsasked the Minister of Transport (1) if he is satisfied with the accuracy of official forecasts of traffic growth in the London area, used to support proposals for an expenditure of 20W £1,000 million on motorways from 1971 to 1983; and if he will make a statement;
(2) whether, in view of the inaccuracies of the Greater London Council forecasts of growth of goods traffic and private cars on roads in the London area as shown in the period 1962 to 1966, he will have forecasts of future growth made by his Department.
§ Mr. MarshAll long-term traffic forecasts need periodic checking and revision. Phase III of the London Transportation Study has already produced revised versions of the forecasts produced by Phase II. The G.L.C. have begun a programme of traffic measurements throughout their area and we are discussing with them further steps to monitor growth of travel in London generally. This information is being taken into account in decisions about road building in London as it becomes available.
