§ Ms Glenda Jackson
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 305W 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.
