Dynamic Models for Transport Scheme Appraisal

This webinar is based on Aimsun guidance, developed in association with the UK Department for Transport, for the development of dynamic transport models for the purposes of transport appraisal. As such, the methodology we present has been overseen by those who oversee Transport Appraisal Guidance. Dynamic assignment is a powerful tool that can provide detailed predictions of travel time across a network over time. However, until now, non-conformance with the Department for Transport's 'Transport Appraisal Guidance' (TAG), specifically regarding convergence, stability, and robustness, has largely restricted the application of dynamic assignment to operational modelling, development planning and event planning. In this webinar, Gavin Bailey and Tessa Hayman of Aimsun outline a method that ensures dynamic assignment models can reach more stable results. The aim is to provide principles and best practice for practitioners to follow when developing dynamic assignment models, particularly in relation to model stability and convergence.
