Colorado Tunnel Ventilation Study
Mechanical ventilation of tunnels is costly because of the initial installation and the continued maintenance and operation. However, at some tunnel length corresponding to a particular altitude, traffic configuration and topography there is a need for this forced ventilation. The study was undertaken to help determine the pollution concentration in existing tunnels in Colorado, and predict the length of tunnels which will need mechanical ventilation. The study indicated that, even at high altitudes, tunnels will vent very well when the length is less than 2000 feet and traffic is less than 1500 vph.
