French Surveys of the Delivery Approach: From Cross-section to Diachronic Analyses

This paper presents a diachronic analysis of two surveys carried out in the city of Bordeaux (France). The first one was performed in 1994, the second in 2013. The interest is that the second survey followed a very similar methodology as the first one performed twenty years previously. It allows us to identify invariant parameters of the complex urban goods movements system, and also to distinguish, for the parameters that have undergone significant changes, those resulting from changes in the city and those resulting from changes in logistics.
