Ponzi accompanies travelers coming from Marconi airport towards Bologna central station, through a new curved connecting compass, made up of 4 Ponzi RID curved sliding doors with slim profiles, enabled as an escape route. In the event of danger, smoke or fire, the doors open automatically, allowing people to escape. The 4 automatic doors are connected two by two by a central anti-panic door with manual handle. Inside the compass there is a large Ponzi Tire technical doormat that covers the entire area following the camber of the doors and profiles.
