The conference


Why attend Modelling World?

We are once again at a critical time in modelling history...


The Department for Transport's Chief Scientific Adviser and Chief Analyst recently announced areas of research interest for 2023. One priority is 'reducing environmental impacts, tackling climate change, improving air quality, biodiversity and ensuring the transport system adapts to be resilient to the effects of climate change'.


The rapid development of modelling capability and tools leaves modellers well placed to help the DfT deliver on these aims.


At the same time, the evolution of new travel, social and economic trends has given the data and modelling community many opportunities – as well as new challenges – as it gets to grips with current uncertainties.


Modelling World 2024 brings together UK and European experts – with a few international provocateurs thrown in – to meet, network, discuss and debate the way forward in an independent, convivial and professional space.

Why attend?

19 June programme


Mercian Foyer

Registration opens: Morning networking and refreshments served


Mercian 1

Opening plenary: the morals of modelling

Chair: Tom van Vuren MBE, Strategic Consulting Partner, Amey, Board Director, Transport Planning Society and Visiting Professor, Institute for Transport Studies, University of Leeds


How do we ensure we best reflect future transport needs in our decision-making?

  • Erica Thompson, Associate Professor of Modelling for Decision Making, Department of Science, Technology, Engineering and Public Policy, UCL

  • John Bates, Transport Modelling Consultant

  • Katie Hall, Business Director, Transport Planning, Systra

  • Simon Lusby, Managing Director & Head of Consulting, City Science

A discussion around reasons why our current approaches to transport modelling can fail to reflect the key decisions that people make when deciding why, where, when and how to travel, and can also poorly address wider societal choices, preferences and implications. Where does this leave the modeller’s responsibility?
