ABSTRACT
The aim of this chapter is to develop a unified framework to model urban phenomena by embedding an explicit choice-theoretical approach into a dynamic context. More precisely, the type of phenomena addressed in the chapter can be given the general heading of mobility processes, that is processes where a (usually large) set of human actors change state over time, according to some evaluation and choice behaviour. The different states occupied by the actors, in the systems of our concern, are geographically distinct, so that a change in state implies a change in the geographical location where some activities are performed. The criteria for evaluation and choice are both exogenous, that is depending on some local features of the different states, and endogenous, that is depending on the interactions among different actors. Typical examples of such mobility systems are:
