The London Planning Advisory Committee (LPAC) established to advise on the planning and development of greater London is required to provide strategic guidance to the Secretary of State for the Environment on several issues, including transport; this necessitated a brief but intensive review of scenarios for transport in the year 2001. This paper describes the study and the background to it. Section 1 indicates the role of LPAC, the terms of reference of the study, and the objectives developed by LPAC for the appraisal of transport scenarios. Section 2 describes the approach adopted to the development of the four alternative scenarios, and the detail and underlying philosophy of these scenarios and variants on them. Section 3 outlines the basis for evaluation and the use made of the TRRL's London Area Model (LAM), of qualitative assessment and of professional judgment. Section 4 presents the results of the evaluation and draws a number of policy conclusions. It notes in particular the lack of freedom for manoeuvre before the late 1990's, the relatively poor contribution of road infrastructure improvements, and the pivotal position of road user charges. Section 5 briefly summarizes conclusions and next steps.
