基于绿色经济的高速铁路潜在价值研究

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

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。

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.
