Transportation Tunnels

Road tunnels are very unique environments. Keeping passengers safe and on the move are the key priorities for tunnel managers and operators. A good Public Address (PA) system can help overcome some of the challenges faced on a day to day basis by providing an effective means of communication between the tunnel operators and tunnel users.

In a tunnel the PA system is the only way of communicating with the passengers once they are outside their vehicles. More often than not these systems are now emergency sound systems, so they are also used as the primary form of communication in the event of a fire or other emergency. In the past some tunnels have chosen not to install PA systems because they realised that it was impossible to deliver clear messages with conventional loudspeaker solutions. HARMAN has made it our mission to provide solutions that can deliver clear and intelligible messages.

HARMAN’s tunnel solutions are not just limited to PA. Our innovative architectural lighting solutions can be used to break the monotony of driving in longer tunnels and to enhance tunnel portals.
