The paper describes a project dealing with the deployment of an e-mobility service for persons with disabilities. The service is focused on the movements of people with disabilities within and between buildings of Sapienza University of Rome, dislocated in different areas of the city. A methodology suited to design correctly the service is explained. For each connection, different routes and electric vehicles are analyzed in terms of travel time, energy consumption and battery state of charge by a software developed by the authors; the most suited routes and electric vehicles can be thus chosen. Amongst the numerous connections analyzed in the project, the paper reports and discusses results of a single case study, in order to show the effectiveness of the proposed methodological approach.
