Advances in Agent Population Synthesis and Application in an Integrated Land Use and Transportation Model

Agent-based microsimulation models of socioeconomic processes require an initial synthetic population derived from census data. This paper builds upon the Iterative Proportional Fitting (IPF) procedure's well-understood statistical properties. While typical applications of IPF are limited in the number of attributes that can be synthesized per agent, a new method introduced here implements IPF with a sparse list-based data structure that allows many more attributes per agent. Additionally, a new approach is used to synthesize the relationships between agents, allowing the formation of household and family agents in addition to individual person agents.
