| 摘 要： | Logit模型通常用于城际间客运量分担率的预测,其理论基础是假设乘客对交通工具选择的效用函数符合Gumbell分布,这与大交通中出行分布的特点是一致的,但是效用函数在求解时存在着困难,为此作者对Logit模型中效用函数的求解方法作了改进,采用粗糙集理论代替层次分析求解效用函数,以增强Logit模型的实用性,并结合哈尔滨-长春和哈尔滨-大连间客运量分担率的预测证明模型的有效性。

| Abstract: | The Logit model is often used to estimate the intercity passenger traffic sharing,based on the hypothesis that the utility function of the passenger's choices of the transportation vehicle conforms to the Gumbell distribution.This agrees with the journey distribution characteristics in the big transportation,but it is difficult for the utility function to obtain the solution.Therefore the author improves the utility function solution in the Logit model with the rough set theory to replace the analytic hierarchy so as to solve the utility function,finally to strengthen the usability of the Logit model.The validity of the model is proved in the passenger traffic sharing between Harbin and Changchun. |
