A simulation model for risk assessment in a smart mobility ecosystem based on the inoperability input-output theory

In our modern society, the vicious circle "urbanization, traffic congestion and lack of security" is choking metropolitan authorities, leading to a declined quality of life, as the demography rises, along with mobility demand. For cities to operate efficiently, urban mobility should be established in a sustainable manner, combining urban planning, mature infrastructures and technological innovation. The mobility landscape is then being reshaped and represents a new constraint in city management, but also innovative opportunities for authorities and business. The design of the mobility ecosystem should then take into account many interdependent systems of which any failure may affect the equilibrium of the whole. This paper proposes a simulation model of the critical infrastructures of the urban mobility, seen as a system of systems. The simulation is based on the inoperability input-output model. The scenario performed allows to analyze different strategies of adjustment in case of external disturbances.
