A computational code implementing experimentally tested mathematical models was used to conduct a study on an urban center of southern Italy comprising the cities of Cosenza and Rende that, seat of the University of Calabria, has recorded a systematic and significant expansion in recent years in terms of both urban and demographic development. In Italy the first electric tramway was built in Florence in 1890 and it linked Florence to Fiesole. In 1920 major tramway development was reached. In Europe, North America, South America and Australia, almost all medium and large size cities had urban and intercity networks. In the late 20s, North America first and then Europe reduced the tramway systems replacing them with trolleybuses and buses. The traction electric motor used in most new vehicles is the four-pole three-phase asynchronous motor, that with its control systems, has introduced a number of advantages compared to the DC motor in terms of reliability, less maintenance, high efficiency and control
