In France as in Europe, mobility and economic growth have been growing at about the same pace for several decades. Growth in freight hauling, which is usually expressed in ton/ kilometer, is more easily explained by the distance covered than by transported weight. This paper focuses on the concepts of coupling and uncoupling, which have been studied for a number of years. Here, coupling means that demand for freight hauling is correlated with economic growth. This perception allows us to analyze the underlying freight hauling logic and to suggest various means of reducing negative externalities. This approach is based on the links between industrial and logistical organizations, the location of activities, and the planning of freight hauling systems.
