In this work we show that some centrality measures in network analysis are exactly an application of the principles underlying the well-known Vickrey-Clarke-Groves (VCG) mechanism. We then present an example relying on a transport framework which highlights how these centrality measures à la VCG can indeed provide valuable information to fairly assess the importance of the analyzed network elements.
In the last years, several Italian legislative interventions concerning the local public transport (LPT) sector aimed at inducing Local Authorities to re-programming the current services by changing the existing transport modes in favor of less expensive ones, while preserving passengers mobility. Indeed, for some local railway routes the existing level demand and its characteristics (e.g. distribution along the day) would justify a switch from rail to bus mode, when the latter are proved to be less expensive in providing comparable services.
