In agent-based microsimulation models for land use (e.g., UrbanSim (2010)) or transportation planning (e.g., MATSim-T (2010)), agents’ decisions are simulated over time in order to predict future states of the system. The initial step is the definition of agents – usually, persons and households. If a snapshot of the entire population of the study area, taken at the simulation’s base year, were on hand, one could use this as an initial placement. Unfortunately, such data is often not available due to privacy and cost constraints. To tackle this issue, one can combine different data sources to derive a disaggregate representation of the agents, matching given criteria like correlation structure and marginal sums. This process is referred to as population synthesis.<br/><br/>We summarize recent efforts to population synthesis for microsimulation (Auld et al., 2010; Pritchard and Miller, 2009; Ye et al., 2009; Srinivasan and Ma, 2009; Arentze et al., 2007; Guo and Bhat, 2007). All of the aforementioned works share two tasks: (a) adjustment of an initial population, taken from a past census or other survey data, to current constraints, and (b) selecting households and optionally assigning them to geographic areas. We describe the above tasks, and analyze and evaluate the characteristics of the particular approaches. This information will hopefully be helpful for the implementation of future population synthesis routines. Show more
