The TASSIM model integrates an urban transportation planning model, vehicle emission factors, and simple air diffusion models in a simulation framework that can be used to analyze the air quality effects of transportation policies. This report briefly reviews the structure of the model and then describes how it was applied to the Los Angeles region. The application required the tailoring of certain components of TASSIM to the peculiarities of the Los Angeles area and the calibration of the model to the regional data. The performance of the model in Los Angeles was then compared with previous experience with Boston for the simulation of the air quality effects of policies that alter the emission rates of automobiles, the character of the transportation system, and the pattern of land use.
