The Bi-level Programming Model and Algorithm for the Interaction Multimodal Traffic Origin-Destination Demands Estimation

考虑各种交通模式间的相互影响 ,利用多模式均衡配流的变分不等式模型 ,建立了拥挤条件下多模式 O-D需求估计问题的双层规划模型 .并在对多模式均衡配流变分不等式模型进行灵敏度分析的基础上 ,给出了关于此类双层规划模型的基于灵敏度分析的求解算法 .

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.
