Road Tunnel Ventilation Systems


Road Tunnel Ventilation Systems

Road tunnel ventilation systems serve to limit the concentration of air pollutants during normal tunnel operation and to transport smoke gases out of the tunnel during self- and assisted rescue in case of fire.

Depending on the tunnel length, the traffic load and type, as well as the likelihood of traffic jams, different ventilation systems, such as longitudinal, semi- or fully transverse ventilation systems, are used. A combination of these systems is sometimes required.
