This paper  presents  the  author's view on  the  role  of
transportation  modelling   in  the   evaluation  of   new
information  technologies  for transportation  users.   It
describes  the  basic  methodologies  in  this   area  and
indicates the challenges and requirements arising from the
new context.   It  finally  reviews  some  of the existing
models in the light of these requirements.
