A GIS based component-oriented integrated system for estimation, visualization and analysis of road traffic air pollution

The integrated emission evaluation system offers entirely new ways of using the emission model and gives additional visualization and analysis possibilities.

Abstract

Road traffic is a dominant source of air pollution. Therefore it is necessary to provide decision-makers with up-to-date emission information in an easily understandable form. To achieve this goal we have integrated existing emission calculation software with a graphical user interface, which includes a GIS (geographical information system) component. The paper first gives a summary of the basic road traffic emission model and then focuses on the design and implementation of the computer application with the emphasis on the used component and GIS technology. The integrated emission evaluation system offers entirely new ways of using the emission model and gives additional visualization and analysis possibilities.
