Reducing carbon emissions in the transport sector is essential for the EU to reach its climate targets. EU policies focus on promoting sustainable mobility while ensuring that regions across Europe remain well-connected. To effectively shape these sustainable transport systems, it is essential to understand the mobility patterns and the motivations behind them. Travel behaviour – which includes choices about when, where, and how individuals travel – directly influences the flow of people and goods, and is shaped by factors like transport alternatives, personal preferences, and geographic location. The rapid evolution of data collection methods has opened new possibilities for analysing and modelling these behaviours, offering deeper insights to support efficient and sustainable transport systems.
