Why attend Modelling World?

Introducing Modelling World 2022, held in Birmingham on 8-9 June 2022. 


For the 2nd time since 2019, we'll be able to meet in person and catch up on months worth of insights and experience from a truly unprecedented time in data and modelling history...


The triple whammy of pandemic response, urgent climate change mitigation and the disruption - possibly for ever - of the transport, social and economic trends we knew and loved (or hated) – has left the data and modelling community with new challenges and opportunities as it gets to grips with a range of new uncertainties.


Modelling World 2022 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.


And don't forget the unique Modelling World buzz - which will be louder than ever this year – the excellent dinner, the UK's top data and modelling exhibition, the Master of Modelling Awards and networking drinks!

Why attend?

Innovation showcase

'No model’ assessments: active travel and shared mobility tools

Emerging transport technologies ask increasingly complicated questions of the models that are used to assess them, and to support design and decisions. Is the only answer making existing modelling tools even more complex? Can the uncertainties surrounding the operation and impacts of these futures change our way of thinking about their assessment?
Over the past few years – in reaction to new travel trends embedded during the pandemic, and now in the quest for to decarbonise transport – Government has been increasingly supportive of active travel, shared mobility and a range of other place-based carbon reduction initiatives.
Innovators from academia, public and private sectors have developed a range of toolkits and platforms enabling the rapid analysis, planning and testing of new scenarios, street infrastructure and design interventions. Others have developed place-based carbon calculators that support more accurate predictions of transport carbon emissions. Data inputs range from AI-driven video sensing to GIS and more traditional metrics such as transport stops, isochrones, PTALs and census data.
For the first time in 2022, Modelling World is organising a showcase of these innovative tools. Delegates will able to see short talks, live demos and network with the creators and users of these tools.

Chair: Tom van Vuren, Regional Director for UK & Europe at Veitch Lister Consulting

Morning Plenary: It wasn’t the computer that said road

This plenary session at Modelling World will hear from David Milner, the author of the ‘Computer Says Road’ report, about his concerns around the role of modelling in current land use planning.


A panel of modelling experts will respond, and the conference chair will facilitate a discussion about how the modelling profession can respond positively to this challenge, for example by:

•    Removing unconscious bias from the models?
•    Revisiting the valuation principles in appraisal?
•    Scenario planning?
•    Educating end users?

Gerry Casey

Senior Consultant, Arup

Gerry lead Arup’s City Modelling Lab, an R&D team working across both fundamental and applied research in city scale simulations. I'm interested in evidence based decision making and modelling for enlightenment, not post-justification.

The City Modelling Lab is an interdisciplinary team, with a mixture of domain experts (in transport, energy, climate change, air quality, and economics), data scientists, software engineers and designers working to make cities better. We work on city scale simulations, for both hard infrastructure scenario testing (e.g. new metro systems) and soft policy testing (e.g. road pricing). We synthesise populations and build Agent and Activity based models of our cities.

We use these techniques and approaches to help us guide decision making on decarbonisation, equitable growth and the possible impact of innovation and disruption (e.g. ride sharing and MaaS). I work closely with academia and I’m interested in both fundamental and applied research in this space.
