A Bilevel Programming Model for Continuous Equilibrium Network Design and Its Solution Algorithm for Urban Transit System
城市公交系统连续平衡网络设计的双层规划模型及求解算法

According to transit network characteristics, transit network is systematically described in this paper. A bilevel programming model for transit network design problem is presented, in which the upper model is a normal transit network design model, and the lower model is a transit equilibrium assignment model. A heuristic solution algorithm based on sensitivity analysis is designed for the model proposed. Finally, a simple example is given to illustrate the application of the model and algorithm suggested.
