T0578 Modelling Approaches Research Study

The required service is to undertake research into approaches to modelling highway scheme impacts alternative to the existing strategic modelling techniques. It is supposed that these alternative approaches may have the potential to better reflect the impacts of schemes whilst continuing to account for reassignment and variable demand responses. In particular, the research is to focus on two main alternative approaches: mesoscopic modelling; and hybrid modelling. TPG are looking to understand whether the application of these approaches would lead to a meaningful improvement in the assessment of schemes, and in what circumstances they should be considered. It is intended that the focus of…
