Application of Rough Set Theory in the Inter-city Passenger Traffic Sharing
Zhu Cong-kun · 2007
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.
