The Evaluation Model: Estimation of Economic, Social and Environmental Impacts of Car Sharing Services

Thischapterdescribesamodelabletosimulatecarsharingconfiguration options, taking into account different dimension of sustainability (environment, economy, mobility and social). We studied the possible effects of such options on the mobility system. In order to identify and structure such effects, we used cog- nitive maps, elicited by means of interviews and workshops made with the researchers with different expertise of the Green Move team and territorial stake- holders. Such maps led to the development of a simulation model for the estimation of the options’ effects. Different sub-models are briefly described in terms of inputs, outputs and operating logic. The model has been used in the design of a full-scale electric car sharing service for the city of Milano.
