基于概率占优的C-Logit随机交通分配模型
A probability-dominant C-Logit stochastic traffic assignment model

摘要 在引入一种新的路径相关性指标基础上,构建了C-Logit概率占优用户均衡(PdUE)模型，给出了其等价形式，C-Logit-PdUE模型不仅保持了原有Logit-PdUE模型的良好数学结构和性质，而且还能合理处置路径叠加问题，最后，借助数值算例对模型参数进行了灵敏度分析，算例结果显示路径叠加问题对交通分配结果影响显著.
Abstract：This paper develops a C-logit Probability-dominant User Equilibrium (PdUE) model in which a new route correlation measure is suggested, and equivalent versions of the new model are established accordingly. The current C-Logit PdUE model is capable of maintaining the superior mathematical structure and properties of the original Logit-PdUE, and meanwhile, it is capable of handling the path overlapping problem. In the end, a numerical example is conducted to perform parameter sensitivity analyses in the model. Results show that the path overlapping problem has significant effect on the traffic assignment consequence.
