Combined Modal Split and Assignment Model for the Multimodal Transportation Network of the Economic Circle in China

This article describes economic circles in China and the use of multimodal transportation networks incorporated into these circles. An economic circle is defined as more than one closely adjoining central cities and their influence zones. The authors propose a combined modal split and assignment model with deterministic travel demand for modeling passengers’ choices of intercity bus and train. These transportation modes are the two primary competing modes in the multimodal transportation network of an economic circle in China. The authors also use a generalized travel cost model of highway and railway to incorporate travel time, ticket fare, and passenger discomfort or inconvenience. On the highway network, the interactions of private vehicles and intercity buses are asymmetric. For modeling this component, the authors propose a variational inequality formulation to describe the combined model; a streamlined diagonalization algorithm is then used to solve the combined model. The article uses a multimodal transportation network based on the Yangtze River Delta economic circle to illustrate the proposed method. The findings show how traveler's mode choices change with different levels of demand, as well as how a reduced train fare affects the passengers' choice of travel mode.
