Greater connection between neighbourhoods and neighbouring municipalities
It has also been estimated that linking the two tram networks would double the number of service users, and that the overground tram line along Diagonal could carry up to 222,000 passengers a day. The project would therefore reduce overall congestion in the city by 0.4%, and the daily number of vehicles using the central section of Av. Diagonal by 12,500.
The unification of the tram network will improve links between various city districts and also make it possible to connect Barcelona with the eight surrounding municipalities (Hospitalet de Llobregat, Esplugues de Llobregat, Cornellà de Llobregat, Sant Joan Despí, Sant Just Desvern, Sant Feliu de Llobregat, Sant Adrià de Besòs and Badalona). This is why it is one of the key factors for enhancing the public transport system, as well as combating the air and noise pollution caused by an excessive use of private motor vehicles in the city.
Moreover, the urban model resulting from the improved tram service is a healthier one, as fewer cars will lead not only to a direct reduction in air and noise pollution, but also to greater road safety. The new tram link is therefore an opportunity to redesign the city and implement a model based on sustainable mobility, which prioritises pedestrians, bicycles, and public transport, with the aim of building a healthier, more equitable and sustainable city for everyone.
This new city model also aims to promote high-quality public spaces (with more urban greenery and more space for pedestrians), reduce air and noise pollution and enhance the efficient management of the city's resources and waste.
