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

International audience ; 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... Mehr ...
