A new model for the analysis and prediction of air pollution, noise and energy consumption generated by urban traffic is described. This model combines an equilibrium assignment with a set of sub-models for energy consumption and generation of pollutants, based on an urban road network and mixed traffic and individual vehicle characteristics. Network links become line sources of pollution, and the dispersal and diffusion of pollutants across the study area from these sources are also modelled. Basic output information includes traffic flows and total energy consumption and pollution data, and additional disaggregation of the output in terms of vehicle type and trip class (eg trip purpose, origin or destination) is available. The model can simulate traffic conditions over consecutive periods within a day or a series of days, so that pollution generation and dispersal may be studied under a variety of conditions, given meteorological data for the study period. An example involving the application of the model to a small urban area is given. This example examines some likely environmental effects of the provision of a new freeway (a).
