Microsimulation model of land use and transportation dynamics is seeing a growing demand for an initial set of agents with detailed socioeconomic and demographic attributes at a disaggregated scale. Creating large-scale spatially detailed synthetic population has become increasingly challenged. To achieve spatial details in microsimulation, data integration in three aspects (topography, demography and firmography) needs to be concerned. Using Singapore as the case study, the work focuses to approximate real-world distribution of topography and demography. For topography part, the work mainly constructs an integrated building database by fusing heterogenous data sources from different agencies, which are semantically different. For demography, the work estimates the joint distribution of household and individual characteristics under multiple levels of constraints. By allocating households into buildings, we can thus initiate microsimulation for land use and transportation system.
