Abstract
In this Paper, I discuss about travel behaviors in networks and the direction ofresearch in the future. Firstly I overview behavior models at two view points of GEV family models and other models. Next loading algorithms for SUE and solutions have developed is shown focusing on logical consistency between behavior models and equilibrium models. Finally I present the point of view those are altermative set generation problem, asymmetry effect on network behaviors and dynamics in travel behaviors in these research area.
