Conference 2021


Why attend Modelling World?

Introducing the long-awaited face-to-face Modelling World 2021 in Birmingham on 5-6 October 2021. 


For the first time since 2019, we'll be able to meet in person and catch up on 18 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 2021 will bring 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?

West Suite

Addressing increasingly complex problems with data and simpler model approaches

The questions that are traditionally answered with strategic transport models get more complex. Traffic flows are up to or exceed their pre-COVID levels. Public transport is still very underused. Cycle flows have stabilised. Underlying travel behaviour has changed, but how? Transport academic Steve Melia, in Local Transport Today, questioned how well our models can predict the effects of road closures and pedestrianisation, suggesting surveys and research, and will share insights in this session.

In this session we will explore if more complex models are the answer; or if this is better addressed by simpler, more transparent model approaches, or the direct use of data. What data techniques exist that allow us to gain such more detailed understanding? What are the risks of oversimplifying? Do dynamics need to be reflected better; is there a remaining role for equilibrium approaches?

Morning plenary: climate change and key technical challenges of modelling carbon interventions
Chair: Tom van Vuren, Director, VLC Europe

  • Introduction to the challenge: Phil Goodwin, Emeritus Professor of Transport Policy, UCL and UWE

  • Decision-making depends on the cost we ascribe to carbon: Laurence Oakes-Ash, CEO, City Science

  • Developing a carbon analysis toolkit for Greater Manchester: Daniel Fisher, Appraisal and Analysis Manager, Transport for Greater Manchester


Context: In a world of climate change, the future will not be sufficiently like the past for modelled transport relationships based on base year and historic trends to be a useful guide to the future.

Similarly, carbon-reducing interventions to reverse or limit climate change impacts pose practical challenges to transport modelling – reducing the need to travel, the increased importance of active modes, and accommodating emerging technologies. How well-prepared is the transport modelling profession to play its role?


Format: This will be an interactive session with plenty of audience participation. Come prepared with your views and insights, based on the work you have done or are doing in this space.

We will use interactive conference engagement tools such as polls, slido and votes to warm everybody up in this first session of the day.

Superforecasting workshop


Led by Warren Hatch, CEO, Good Judgment

In this interactive workshop, we will apply Superforecasting strategies from new research to modelling challenges.


We will cover three core concepts with real-world illustrations:

  • cognitive bias mitigation

  • noise reduction

  • information filtering


These strategies are evidence-based to improve the accuracy of forecasting and are designed to be complementary to existing processes​.

For those that wish to delve deeper, here is Good Judgment’s ‘Forecasting Aptitude Survey’, which interested participants can complete before the event

The link takes you to an online personality quiz that measures characteristics that Good Judgment found to be highly correlated with forecasting accuracy. These are of course optional and entirely anonymous. At the end of the quiz, you will receive your individual results, so please take a screenshot or make a note if you would like to keep a record. Then we will be sharing the aggregated results at the workshop.

Closing plenary: who are the modellers of the future?

Session facilitated by Tim Gent, Technical Director, Atkins


Participants include:
*Aruna Sivakumar, Centre for Transport Studies and Director, Urban Systems Lab, Imperial College London

Keith Buchan, Skills Director, Transport Planning Society

John Parkin, Professor of Transport Engineering, University of the West of England

Sherin Francis, Principal Transport Planner, Jacobs & Katie Pearce, Senior Transport Planner, Jacobs

Fred Ewing, Managing Consultant, Meridian Business Support

Claire Cheriyan, Strategic Analysis Manager, Transport for London

Devrim Kara, Director, PTV UK


Issues include:

  • What we mean by ‘a modeller’? Who are these strange people in practice, and what skills do they have/use?

  • How do modellers get created? Where do they come from?

  • Acknowledge the huge diversity in both these points: transport modelling is a tiny profession splintered into many sub-disciplines.

  • Supply/demand problems: We always seem to be ‘short of modellers’. Is this definitely true, and why?

  • Future needs in terms of volume and type of modellers and issues of diversity and inclusion

  • How do we work together to achieve that? Who needs to be involved?
