Abstract

In this chapter, we present a multi-agent system that models and simulates the dynamics of intra-urban mobility through the automated formation and evolution of both groups of households and groups of housing-units. We consider global rules of evolution instead of individual events to represent the evolution of both the population and the housing-stock. The moving mechanism is modelled by interactions between groups and urban-sectors agents in a simulated housing market. We have tested this system on the basis of several censuses datasets of Bogotá city. The evolution of groups has been simulated over 20 years and compared to real data. The results of group formation and evolution mechanisms have been compared to classes produced by classical classification methods. Very good correlations have been found. The simulated population has been compared to real distributions of several Bogotá districts and appears to be close for an important number of them.
