This webinar will look at three cities (Adelaide, Auckland and Brisbane) and the approaches adopted for modelling work between the differing platforms (macro/meso/micro) and their intended uses, with a particular focus on modelling constraints. This session will help provide modellers with some insight into how different regions use their models to address their objectives and a chance to interact with the speakers at the end of the session (after all three presentations have been completed).
The three presentations are:
1. “It’s hard not to Gridlock – Constrained Capacity” - John Davies
John will briefly set out the challenges to the vision of integrated macro/meso/micro model systems and give some insights into what Auckland is currently doing to manage this in a pragmatic way. This will focus on demand/supply concerns and network capacity issues, as well as the capacity of people, process and models. Some thoughts related to microsimulation modelling issues will also be covered. John will include some things that Auckland is trying to resolve these challenges.
2. “Citywide Mesoscopic Modelling: Challenges in application with the Brisbane Mesoscopic AIMSUN Model” - Tejas Trivedi
The presentation will focus on insights gained into challenges through development and application of a large-scale mesoscopic model in a variety of projects. The challenges range across model development, linkages to the strategic demand model and sub-area project models applications. The presentation will explore the opportunities in current modelling practice, with the case study of the Brisbane Mesoscopic AIMSUN model.
3. “Development of South Australia’s integrated modelling framework” – Keyvan Pourhassan, Chris Mayer and James Parrott
This presentation will cover some of the nuances of the Adelaide Travel Demand Model; in particular, with respect to constraining capacity. It will also cover the integration between the demand model and the Greater Adelaide Mesoscopic model, the challenges associated with this task and some of the approaches adopted to address them.
