Gotthard Road Tunnel, Göschenen Thermo Portal

As the thermo portal in Airolo has proven itself, ASTRA 2014 has decided to also install a “thermo” portal on the north side of the tunnel for lorries travelling south.

The “thermo” portal looks out for potentially overheated vehicles 1,200 m before the north portal of the Gotthard Road Tunnel. All vehicles are checked both geometrically and thermally in the normal traffic lane at normal speed and assessed in real time. If the system detects overheating in a vehicle (engine, tyre, load), a red light au-tomatically appears via the traffic control system. The vehicle is picked out and further inspected. If necessary, the vehicle is taken off the road.
