The London Transportation Study and beyond

Abstract

Ridley T. M. and Tresidder J. O. (1970) The London Transportation Study and Beyond, Reg. Studies 4, 63–71. The London Transportation Study was carried out in three phases. Phase I collected basic data on person and travel characteristics in 1962. Phase II made the first forecasts of potential demand for travel in London in 1981 assuming certain population, employment, income and car ownership levels and that car owners in future would behave in the same way as in 1962. Phase III extended the previous work and developed methods which allowed the testing of alternative combinations of road and public transport networks, the estimate of road travel demand in balance with capacity assumptions and the economic evaluation of networks. The paper briefly describes the methods used, the tests carried out and shows how the new methods produced revised estimates of future travel. The implications of these results and the possible effect of revised planning assumptions are discussed.
