基于绿色经济的高速铁路潜在价值研究

Logit模型是一种较为成熟的旅客运输分担率分析方法,它在旅客运输领领域有着广泛的应用。参照绿色经济的定义,首先,本文分析各运输方式的安全性效用、经济性效用、时效性效用、准时性效用、方便性效用、舒适性效用和绿色性效用7个服务特征属性并建立广义效用函数;其次,研究高速铁路客流分担率模型;再次,运用相关数据及最大似然估计法来确定模型的参数;最后,以武汉~广州间各运输方式的客流分担率来研究该模型的应用。

Research of High-speed Railway’s Potential Value Based on Green Economy

Logit model,a more mature passenger transport share rate analytical method,which is widely used in the field of passenger transport. Reference to the definition of green economy, firstly, this paper analyzes 7 service characteristic properties,such as security utility,economic utility,timeliness utility,punctuality utility,convenience utility,comfort utility and green utility,and establishes a generalized utility function;secondly,this paper studies the share rate model of high-speed railway passengers flow;once again, this dissertation uses relevant data and maximum likelihood estimation method to define the parameters of the model;finally,this thesis takes the passengers flow share rate of all kinds of transport modes between Wuhan and Guangzhou for example to research the application of the model.
