摘　　要：基于随机效用理论的多项logit(MNL)模型常用来解决多方案选择问题。介绍了该模型进行个体出行模式决策分析的方法,建立了线性效用函数假设条件下,个体出行模式选择概率与模式特性变量之间的近似线性关系。最后通过一个两模式决策分析的简例说明该模型的用法及灵敏度分析方法。Muhinomial Logit model （MNL） based on the discrete choice theory is often used to solve the problem about multi-alternatives choice. A method for analyzing individual behavior of travel mode choice by this model was introduced. The approximate linear relation between mode-choice probability and attributes variables of travel modes was established under the assumption of linear utility function. In the end, an example of binary mode choice model is applied to illustrate its usage.
