The integrated computer system for modelling of air pollution based on the digital data

The paper presents the integrated computer system for modelling emission and dispersion of car exhaust pollutants in mesoscale. Whole data used in system, concerning information about topography and meteorological condition are gained from GIS. The model of traffic flow is based on well-known safe distance Krauss models. Calculation of pollutants concentration is based on Gaussian finite line source model (GFLSM). In computational system all results of simulation can be visualized and export in acceptable formats to geographical information system. This causes that proposed system has almost unlimited chances in analyses of car exhaust pollutants over space and time.
