The transition from strategic to mesoscopic modelling
This paper describes recent trends in mesoscopic transport modelling, with a particular focus on the challenges faced in the transition from strategic transport models to mesoscopic transport models. Jacobs have undertaken a number of recent projects requiring the creation of mesoscopic model matrices (often for dynamic models), which rely on strategic transport models for supplying input demand data. Matrix estimation has often been part of this process, and the paper discusses the learnings we have gathered through this experience, such as the impacts to matrix size, average vehicle trip lengths, the various matrix estimation control factors and their outcomes/effects. A variety of matrix growthing processes have also been considered based on estimation outcomes. The paper includes discussion on the various challenges in transitioning from strategic to mesoscopic models, with potential solutions offered and also two recent case studies to demonstrate approaches that have been adopted.
