Trieste (Italy)

Trieste is situated towards the end of a narrow strip of Italian territory lying between the Adriatic Sea and Slovenia, which lies almost immediately south and east of the city. Built mostly on a hillside that becomes a mountain, Trieste’s urban territory lies at the foot of an imposing escarpment that comes down abruptly from the Karst Plateau towards the sea.

It has a dense network of bus lines connecting all of its neighbourhoods and is connected to the Karst plateau by an historic tram. There is also a regular daily ferry service between Trieste and Muggia.

Plans and policies

Trieste doesn't have a SUMP established according to the EU guidelines, but an Urban Traffic Master Plan approved by the city council in 2013.  It came into force after a complex process of participation by citizens and stakeholders. It points to a more sustainable urban mobility. Among the aspects that characterize the plan there is the assumption of a scale of values between the different components of mobility which encourages the weaker users: pedestrian and bicycle mobility in the first place, public transport and, finally, private traffic and parking.

Among the major changes proposed in the plan there is the establishment of new pedestrian areas and walking trails. These interventions also aim to pedestrian link between the main parking facilities surrounding the old town and the areas of greatest interest, in order to invite people in the historic center to leave the car in the end of the first row, where there are already several parking areas. This change of habits can lead to a significant improvement of the environmental conditions in the city center.

Great attention has been paid to the needs of certain groups and, in particular, the disabled persons, ensuring accessibility to the pedestrian axes for the vehicles serving the disabled, taxis, and emergency vehicles.
The plan also extended a development of bike lanes and pedestrian paths involving mainly the flat areas and the densely populated areas of the city. The plan also identifies some solutions to promote public transport, including a significant increase in reserved lanes / roads.
