Abstract:

With the development of regional economic integration, the cooperation and integration between the regional public transport systems have been paid more and more attention. This paper proposes a bi-level programming model to describe a kind of integrated transit system across the jurisdictional borders in China. In the upper level problem, the local transit authorities in adjacent regions cooperatively plan and manage the inter-region transit lines, with an objective of maximizing the social welfare. In the lower level problem, the local transit operators in these regions open their local transit markets to each other and jointly operate the inter- region transit lines. They compete with each other to maximize their own profits. In order to obtain more accurate analysis results, the proposed model explicitly consider the stop congestion cost and in-vehicle crowding discomfort cost of the passengers. Numerical studies show that the transit authorities can guide the competitive behaviors of the operators, and then improve the benefits of all participants in the cross-border transit system.
