In many Japanese provincial cities, undesirable outcomes such as atmospheric pollution and traffic congestion emerge caused by motorization. It also raises the need for the transportation options for the aged people and children. The introduction of LRT system with high operation performance and preferable environmental impacts attract attention of policy makers. On the other hand, few researches have dealt with the commutes by bicycle and the transfer on foot while these account a great rate in the urban area transportation. We focus on the effects of the introduction of LRT and related transportation policies in Okayama and Soja city in Okayama Prefecture by applying spatial interaction model, logit model for the transportation mode choice. We then employ the system optimum assignment, user equilibrium assignment and stochastic user equilibrium assignment model to evaluate the route choice behavior. Bicycle and walk options are also taken into account.
