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.
