Modelling World 2026
17-18 June 2026, The Met Hotel, Leeds
Why attend Modelling World?
Are our data, tools and process up to the task? Questions and topics that we will address at Modelling World 2026 include:
-
Reflecting the complexities of transport systems. Examples of modelling approaches that focus on integrating modes, transport and spatial planning, and different spatial levels of decision-making
-
Enhancing existing model approaches to respond to the new challenges – examples of non-traditional modelling techniques that put people front and centre, and enable the benefits of integration to be evidenced
-
Are current data sources and survey techniques up to the task? Modelling World will offer the opportunity to showcase emerging data sources and innovative ways of understanding people’s travel behaviour
-
How is artificial intelligence making a difference? Examples and applications of artificial intelligence that make modelling better or faster
-
Responding to the Green Book Review – do models need to be simpler and faster, or more comprehensive?
-
Are developments in open data and open source models delivering the advances we expected?
-
Activity-based models – have they matured enough for mainstream usage?
-
Allowing for dynamics – both within days, between days and in the long term
-
Improving behavioural representation over and above utility maximisation
-
Connected and autonomous vehicles – what can we learn for use in modelling the current vehicle fleet and operations
-
The post-COVID world – do models really need to change?
