Analysis of Electrical Urban Transportation Systems from the Energy Standpoint 911742

Energy resources are now limited and the increasing demand impose a carefully management of them. The transport demands a considerable portion of total energy resources and in recent years many efforts were made towards planification and technological improvements. In Argentina the Federal Energy Authority has began in 1985 a Program towards saving and rational use of energy. As a part of the program, a group of engineers has developed studies about urban transport energy planning, considering multimodal systems in which electricity plays an important role as an intermediate link that allows to employ many different energy sources.
In expanding countries the urban transport depends nowadays basically from fuel powered motor buses and large investments in future years will be requiered for the installation of other systems.
