  Nowadays, it is possible to collect precise data describing movements of
public transport. Specifically, for each bus (or tram) geoposition data can be
regularly collected. This includes data for all buses in Warsaw, Poland.
Moreover, this data can be downloaded and analyzed. In this context, one of the
simplest questions is: can a model be build to represent behavior of busses,
and predict their delays. This work provides initial results of our attempt to
answer this question.
