The new Sustainable Urban Mobility Plan (SUMP) in Terrassa established the action plan for 2016-21. It incorporates a group of measures aimed at reducing the accident rate, noise pollution and energy consumption, which allows for an improvement in environmental quality and the habitability of the streets. Also wants to increase the autonomy of the children, the elderly and disabled people.
Besides public transport such as rail, metro, tram and bus networks, collective passenger transport also covers car-sharing, car-pooling and flexible mobility services such as train-taxi schemes and demand-responsive transport in areas of low demand.
Improvements to public transport services may address public transport vehicles and related infrastructure, as well as management techniques.
