The Bi-level Programming Model and Algorithm for the Interaction Multimodal Traffic Origin-Destination Demands Estimation
模式间相互影响时估计O-D需求的双层规划模型及求解算法

Interaction among traffic modes on mixed traffic network is considered in this paper, a bi\|level programming model based on the variational inequality of multimodal equilibrium assignment is established for origin-destination demands estimation. Then sensitivity analysis is presented about the variational inequality of multimodal equilibrium assignment, and a heuristic algorithm based on sensitivity analysis is proposed. Finally a numeral example is given.
