Abstract

Increasing greenhouse gas (GHG) emission is one of the most important concerns of world decision-makers. The considerable part of it belongs to the transportation systems. As a solution, the world is going to use urban electrical transportation systems, and thus designing optimal methods and novel strategies is essential nowadays. Indeed, reducing the amount of consumed electrical energy and having optimum and efficient energy management for electrical means of transport requires several vital elements. Designing a travel profile is one of the most crucial parts of these methods. A travel profile for the fully electric train ET245 with three stations is designed and analyzed in Milan, Italy, as a case study in this paper. As the first step, route data are acquired by the Google Maps tool. Then, the train data is collected from the manufacturer's catalogues and datasheets. Finally, computations were performed by Excel spreadsheets. The results indicate that the designed path in the proposed travel profile is covered by a commercial speed and requires reasonable electrical energy, which is considered economical and advantageous.
