The problem of macroscopic modelling of freeway flow dynamics is addressed in this paper. Existing . simple and high order continuum models are examined, modified and treated numerically. Subsequently they are implemented to a number of situations representing uninterrupted and interrupted flow conditions in order to assess their effectiveness. This is accomplished by comparing model results with a data base generated through a detailed microscopic simulation program recently developed by the FHWA.The problem of multilane dynamics is also addressed.
