Quasi-steady-state, analytic air quality models for various types of roadway tunnels are presented. These models can be used to estimate the concentrations of pollutants in roadway tunnels and to determine vehicular emission rates. These models are used to evaluate formaldehyde concentrations resulting from the emissions of methanol-fueled vehicles. It is shown that, within the expected emission rates of methanol-fueled vehicles, formaldehyde concentrations in roadway tunnels are not likely to be a health concern for the general public. One possible exception is during heavily congested traffic conditions; during these conditions, formaldehyde concentrations may result in eye irritation for sensitive individuals.
