Integrated Decision Model of Mode, Line, and Frequency for a New Transit Line to Improve the Performance of the Transportation Network

Abstract

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.
