DEVELOPMENT OF A NEW URBAN LINE WITH INNOVATIVE TRAMS

The trend of the population increase combined with the global climate change and the rising energy prices make sustainable mobility a big issue for urban communities. Since in urban areas it is in act a process of infrastructure development, the modernization of Light Rail Vehicle (LRV), whose final purpose is to intensify the urban transport network in an environmentally friendly way (reduction of visual and noise pollution), will be chased too. This paper is focused on a study developed in the North of Italy (Brescia) and its target is to plan a new tramline without catenary to reduce the urban and architectural impact of infrastructure. In this way, it is possible to reduce the environmental impact especially in specific areas of an urban centre. The work analyses the use of the batteries and the main parameters to size the storage system technology in order to supply the tram correctly whenever it crosses the catenary free section.
