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?
