Traffic flow modelling : what do we know ?


Abstract :

This survey presentation tries to identify to what extent the state of the art in traffic flow
 modelling meets the requirements given by empirical field observations.
The presentation will first present the main features of traffic flow as they can be derived
from field measurements. It will then make a review of the (few)  concepts widely
accepted  in traffic flow modelling, and of the more numerous points on which tentative
models do exist but are either incomplete or controversial. It will conclude with some
considerations on the comparison between models and field observations.
