A proposal for a self contained electric bus service for medium sized cities

Many medium sized Italian cities present pollution problems, due to their geographical position and climate conditions and mainly due to congested traffic flows. Impacts on the health of residents are becoming more frequent and also risky. Thus different policies have been proposed to reduce environmental effects. Among these, the use of low or zero emission vehicles both for private and public transport. In this paper a fuel cell self contained bus system is proposed for a medium sized town. Moreover its economic feasibility has been evaluated taking also into account residents health advantages.
