I buoni risultati ottenuti con il termoportale presente dal 2013 all’entrata sud della galleria autostradale del San Gottardo, hanno spinto l’Ufficio federale delle strade (USTRA) a installarne uno anche sul versante nord. I due termoportali, gestiti entrambi dal Centro d'intervento del San Gottardo, costeranno circa tre milioni di franchi con costi d’esercizio annuo di 600’00 franchi.
Il portale termico consente di prevenire gli incendi individuando i veicoli surriscaldati e bloccandoli per tempo. Il nuovo impianto di Göschenen, definitivamente operativo una volta ultimati i test in corso fino a fine gennaio, permetterà di migliorare ulteriormente la sicurezza all’interno del traforo.
Il termoportale di Airolo ha evitato 24 situazioni critiche nel 2014
L'apparecchio, dotato di tecnologia laser, in funzione ufficialmente dal 4 marzo 2013 ad Airolo è in grado di rilevare le dimensioni del veicolo e di determinare le temperature delle singole componenti tramite due videocamere a infrarossi: se risulta surriscaldato, il mezzo viene bloccato. Ciò che nel 2014 è successo 24 volte.
