Tunnel Ventilation – State of the Art

The use of the term tunnel in this paper refers to all transportation-related tunnels including highway tunnels, transit tunnels such as metro and subway, and railroad tunnels. From a ventilation viewpoint highway tunnels are defined as any enclosure through which vehicles travel. This definition includes not only those facilities that are built as tunnels, but those that result from other construction such as development of air rights over roads. All highway tunnels require ventilation, which can be provided by natural means, traffic-induced piston effects and mechanical ventilation equipment. Ventilation is required to limit the concentration of obnoxious or dangerous contaminants to acceptable levels during normal operation and also to remove and control some and hot gases during fire-based emergencies. The ventilation system selected must meet the specified criteria for both normal and emergency operations and should be the most economical solution considering both construction and operating costs.
