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 report supplies data on short tunnels in Colorado and predicts concentrations of pollutions in longer tunnels based on formulas now in existence. Vehicle emission data for high altitudes is also reported. (Author modified abstract)
