To ask the Secretary of State for the Environment, Transport and the Regions what proposals he has to review the NRTF means of appraisal for traffic generation. [6873]

My Departments advice on traffic generation is contained in Volume 12 of the Design Manual for Roads and Bridges. Section 2, Part 2, Guidance on Induced Traffic. This was revised in February 1997, following experience with the advice issued in December 1994 which implemented recommendations made by the Standing Advisory Committee on Trunk Road Assessment. There are no proposals for further revisions at present. The National Road Traffic Forecasts are a forecast of traffic growth, not a means of appraisal.
