The research and development of new alternatives for the improvement of urban transportation of passengers has dizzily increased all over the world. The population growth is the biggest difficulty for the creation of new lines in dense urban spaces provided with consolidated constructions and equipments, has been lately forced to a more intense search of innovative solutions suitable to these scenes present in big cities. New concepts resulting from the problems experienced today by urban transportation, has grown stronger, according to time, hierarchy of values and contemporary mentality of our society. In this sense, the efficiency in urban transportation has been related to the existing integration of means of transportation, that is, the more numerous forms and options of transporting, the easier and more comprehensive solutions has been found. In view of the new transportation needs, public and private companies have been considering a new way or option on the passenger transportation modality, using an elevated track. The elevated road complements the possibility of an underground via (subway) or via in the level of soil (streets, avenues, etc...), frequently as the only viable alternative so as to avoid expropriations, demolitions or even the use of alternatives highly restrictives to the use of street space by the pedestrian and other more noble public services, being applicable where it is not possible anymore to improve or vitalize urban transportation for lack of physical space at ground level and due to the high cost of via underground. Presently, the elevated roads are the cheapest and rational mode to obtain an exclusive road, free and independent from any obstacle or other elements installed on the ground level, adaptable to any type of geometry or geometrical accidents (ramps, curves, transitions and railroad switches), allowing an automated regular operation and of high speed.
