综合客运通道铁路客运专线客流分担率模型

Passenger-sharing rate model of Passenger Railway Line under integrated passenger transport channel

随着高速铁路和铁路客运专线大规模建设,通道内运输供给能力极大提高,加剧了各种客运方式间竞争力度。文中以交通工具为依据构建了客运通道全出行方式集合,在考虑出行者收入、出行目的和出行者属性(有无自驾车)等因素对旅客出行时间价值影响基础上,增加了LOGIT模型的衡量指标,重新定义了效用函数和分担率模型,对各个模型参数进行分析和标定。以成渝客运通道为例,通过当前调查数据确定特征系数,在此基础上,设定成渝铁路客运专线和高速公路复线建成通车后通道各种出行方式服务属性参数,估算出铁路客运专线客运分担率。

With the passenger railway line and high-speed railway opening,the transport service capacity grows fast,which also leads to more and more intense competition of various passenger transports.In this paper,we build the passenger transport model and also add Metrics in LOGIT model based on the selection of all travel methods,in considering the influence of traveler income,trip purpose and traveler attributes （self-driving or not） and other factors on the value of travel time.Then,we re-define the utility function and the sharing rate model.Taking the Cheng-yu expressway as example,we determine the characteristics of coefficients through the current survey data and estimate the share of passenger railway line transport rate and others transport models.
