Disaggregation of Spatial Data for Transport Modelling (2001-2003)

This project supported the work by the City of Dortmund for the city's new transport plan ('Masterplan Mobilität'). The task was to spatially disaggregate socio-economic data, in particular employment data available only at very aggregate level to the travel analysis zones (TAZ) of the transport model applied. For this a methodology was developed in which the data were first disaggregated to small raster cells using ancillary information such as land use maps and then aggregated to the TAZ.
