Tunelový Rozhlas Case Study

Slovakian highway construction and maintenance company, Národná dialničná spoločnosť, a.s., recently deployed a sophisticated ASL Voice Alarm (VA) system for three motorway tunnels on the D1 and D3 motorways which bypass the city of Žilina in Northwest Slovakia, spanning over 6km of road. The brief was to provide an EN 54-compliant system for a series of motorway tunnels to allow for the safe and trouble-free evacuation of people in case of a fire event or traffic accident. The system had to cater for acoustic challenges of tunnels and to be centrally controlled and monitored.
