In the European Recommendation COM (2007) 551 final, we find that, in the European Union, over 60% of the population lives in urban areas. Urban areas now constitute the living environment of the majority of the population and increased traffic in town and city centers has resulted in chronic congestion. Every year nearly 100 billion Euros, or 1% of the EU’s GDP, are lost to the European economy as a result of this phenomenon. The analysis of the means of transport presented here will show which electrical vehicle is the solution for non-polluting transport according to each specific need. ICPE SAERP, together with RAT Bucharest, has modernized classic tramcars, equipping them with three-phase inverters and asynchronous motors and a partially lowered floor. By 2011, 18 tramcars will be modernized. ICPE SAERP, together with ASTRA BUS Arad, produce and deliver in Bucharest new trolleybuses with lowered floors, equipped with three-phase inverters, with asynchronous motors and with converters for the auxiliary services and for the air conditioning system. Also the trolleybus has a protection device against high voltage present on the body of the vehicle, which is controlled by means of a DSP processor in the master controller. The methodology used in our research is presented in this paper and the results that led us to the conclusions that the type of public transportation proposed is cleaner, more reliable, more efficient and more comfortable than others. Keywords: light metro – LM, metro, tram, trolleybus, urban electric transport.
