- This paper aims to integrate mode, line, and frequency for a new transit line. The model has a bi-level structure in which the upper
level of the model is formulated to determine mode selection, line configuration, and frequency, whereas the lower level of the model
is formulated to determine mode share and link flows in order to reflect travelers behaviors related to choices of modes and routes.
An application of the proposed model uses a test network. The results of this application show that the proposed model performs
better than the existing methods. The model realistically simulates the influence of a new transit line on its surrounding network by
reflecting changes in travelers behaviors according to the transit lines construction, and it also provides a theoretical basis for the
evaluation of the feasibility of the planned investment in a new transit system.
