Monitoring trucks to reveal Belgian geographical structures and dynamics: From GPS traces to spatial interactions

Résumé

Despite the fact that freight transport has a huge impact on the economy and the environment, datasets have always been scarce or restricted to very small a-spatial samples. We here aim at diverting spatial data collected in Belgium for tolling trucks proportionally of their use of the road network, and at further extracting geographical structures and dynamics out of this massive dataset. The paper first relates to the numerous problems encountered when using and transforming big data generated by On Board Units GNSS (cleaning, transforming and preprocessing), second it maps and comments movements (traffic) and stops of trucks within the entire country, and finally partitions the country into mathematical communities of places that most interact. Analyses are performed for the complete sample, but also for sub-categories based on the country of registration underlining the spatial specificities of freight transit in Belgium. This exploratory spatial data analysis enables to reveal multi-level spatial structures associated to urban hierarchies, transport infrastructure but also firm locations or political organizations, tickling the complexity and interconnectivity of any measure taken for a more sustainable future.
