This is achieved through the identification of the optimal train speed profiles employing a novel modeling framework based on Data Envelopment Analysis (DEA). Train speed profiles are selected with the objective to transfer more passengers in less time and with less energy under scheduling constraints. Given that DEA is a data oriented, non-parametric method, a large-scale experimental camping has been carried out over an operational tramway system to collect the required inputs/outputs. Numerical results show that when the proposed approach energy consumption can be reduced by 10%. © 2021, Springer Nature Switzerland AG." }
