This is currently only available in paper format. We will scan this study and release it on the Department's website in March. We have identified a number of further reports, released before web publishing was the norm, which we will also release in electronic format alongside this SACTRA study.
The Department has ensured that the findings of the 1994 report are reflected in assessments through advising promoters about appropriate modelling techniques. For the largest proposals, using multi-modal models means analysis takes account of the impacts of generated traffic in assessments. For smaller schemes, the Department has recommended the use of more proportionate but robust approaches.
The specific guidance for road proposals is introduced in TAG Unit 2.9, ‘Variable Demand Modelling—Advice Overview’. For the larger studies, the advice is introduced in TAG Unit 1.2.1, ‘Multimodal Studies: Introduction to Guidance on Multi Modal Studies’. These are available at:
