5. Conclusion
This paper proposes new type of combined mode and route choice network equilibrium model where the
travellers are assumed to choose their mode considering whole of their trip-chain. Furthermore, since the common
lines problem is considered in the public transportation assignment, it is possible to describe the passengers' route
choice behaviour more rationally. The proposed model is formulated with the Variational Inequality Problem and
the relaxation method is applied to solve the proposed model. Finally, the proposed model is applied to a small
network and the validity of the proposed model is confirmed. As a future work, since the proposed model remains to
be a static model, it is worth considering a dynamic effect. Also, the proposed model would be applied to a real
network.
