Mons, a medium-sized city located in Wallonia (Belgium), is congested with cars on the morning and the evening.

This article presents original research based on data from the “Fédération Wallonie-Bruxelles” of 2018. The first part presents the distribution of school ... [Show full abstract] facilities, and the minimum possible distances students should travel. The results show that the distribution of secondary school facilities is not perfectly adapted to the place of residence of adolescents. Then, the distances travelled will be highlighted, as well as a comparison with the minimum possible distances. The last results show a difference between the distances travelled by the primary school students, between the intramuros and the extramuros of Mons. To conclude, future research directions will be presented, in connection with the current health crisis and supporting a more transdisciplinary and systemic approach where density of students benefits are less obvious in view of the observed motility.
