x Modal split (Mode choice). In this step the share of different modes of transport in total trips is estimated. Mode
choice models usually have a logit character and use either generalized travel cost or travel times quotient of
different transport modes as a utility function.
x Trip assignment. This step involves searching the shortest path between defined TAZ’s. There are plenty of
procedures, from the simplest ones (single route, all or nothing), to more sophisticated (multi route, stochastic
equilibrium).
