The Raster Module is an add-on module for land use / transport models for modelling locally important environmental impacts and their social implications. The Raster Module uses zonal and link-based outputs from aggregate models, disaggregates it to raster cells of 100 x 100 m in size, applies grid-based analytical and dispersion models for assessing environmental and social impacts and aggregates the results to indicators. The results of the Raster Module are indicators such as emissions, land coverage, environmental quality, exposure of population to NO2, PM and traffic noise and graphical presentations in form of concentration maps for air pollution and of noise level maps. The Raster Module has been successfully implemented as part of the PROPOLIS system in the case study regions Bilbao, Brussels, Dortmund, Helsinki, Inverness, Naples and VizencaThe Raster Module is developed as an independent software package. It post-processes land use transport model output provided in a standardised ASCII format and GIS databases provided in MapInfo or ArcGIS ASCII output formats. It currently loads output of the PROPOLIS models (MEPLAN, TRANUS, IRPUD) and their corresponding GIS databases, but might be extended to other land use transport models.
