%X This work analyzes methods for the identification and the stability under perturbation of a territorial community structure with specific reference to transportation networks. We considered networks of commuters for a city and an insular region. In both cases, we have studied the distribution of commuters? trips (i.e., home-to-work trips and vice versa). The identification and stability of the communities? cores are linked to the land-use distribution within the zone system, and therefore their proper definition may be useful to transport planners.
