Progress towards a free, open-source, spatially detailed, multimodal, and all-purpose transport model for Great Britain

Knowing how, why, when, and where people travel is essential for many forms of transport analysis. However, data is often hard to find as it is either expensive (mobile phone data), only considers specific journey purposes (census travel to work data), or specific modes (train ticket data). This paper reports on producing an open-source transport model covering all modes and journey purposes. We highlight novel uses of existing datasets and present preliminary results applicable to the transport planning and research communities.
