During the pandemic of COVID-19, the demand of the transportation systems are drastically changed both qualitatively and quantitatively and the network has become obsolete. In this article, we study the problem of finding an optimal subnetwork that guarantee that (i) the minimal access time from any node of the urban network to the new network is not \em too large compared to the original transportation network; (ii) for any itinerary, the delay caused by the deletion of nodes of the transportation network is not \em too big; and (iii) the number of nodes of the transportation network has been reduced at least by a known factor. A solution is optimal if it induces a minimal global delay. We model this problem as a Mixed Integer Linear Program before applying the model on a real-case application on the Lyon's buses transportation network.
