Road Tunnels: Emissions, Environment, Ventilation

Due to a steady tightening of emission laws for cars and changes in the risk assessment of a tunnel fire, some design data need constant updating. The Report of the PIARC Committee on Road Tunnels to the XXth World Road Congress, 1995 (20.05.B) reviews the art of tunnel ventilation over the last 15 years.

In the present publication new design information and some references are given for dimensioning a longitudinal and a semi-transversal ventilation system.
