To address this increase and reduce private vehicle use, it is estimated that public transport should increase daily trips by 1.5 million, 50-60% more than current levels.

Interurban and metropolitan buses are expected to experience the most notable growth, with a projection of nearly one million daily trips, representing a 180% increase. This highlights the need to equip metropolitan roads with robust public transport, featuring dedicated and segregated lanes. Significant increases are also expected in Rodalies (+85%) and Ferrocarrils de la Generalitat (FGC) (+69%), while urban buses (+39%) and the metro (+31%) will see more moderate growth.

One of the pillars of this transformation is the so-called

This paradigm shift in metropolitan mobility aims to reconnect different municipalities, build new transport interchanges, and concentrate density where public transport demand will be highest. Additionally, the creation of new infrastructure, such as the

Both experts and mobility officials argue that Rodalies will play a crucial role in structuring mobility throughout Catalonia, as the greatest opportunities for densification are found outside the AMB. The key is to offer an accessible and reliable service to convince users to forgo private vehicles.
