Abstract
Macroscopic traffic flow models forms arguably the largest family in the model tree, see page 15. They describe traffic flow as if it were a continuum flow and are often compared to, or derived in analogy with, continuum models for fluids. Individual vehicles are not modeled, however aggregated variables such as (average) density and (average) flow are used.

This assumption is related to the continuum assumption, stating that the flow can be described as if it were a continuum instead of individual particles. The validity of this assumption is discussed in more detail in Sect. 7.1.1.
