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 large-scale construction of high-speed railways and railway passenger dedicated lines, the transportation supply capacity within the channels has been greatly increased, intensifying the competition among various passenger modes. In this paper, a set of all-encompassing modes of passenger transport corridors is constructed based on the transport. Based on the influence of the traveler’s income, travel purpose and traveler’s attributes (with or without self-driving) on the travel time value of passengers, the LOGIT model is added Indicators, the redefinition of the utility function and sharing rate model, the parameters of each model analysis and calibration. Taking Chengdu-Chongqing Passenger Transport Corridor as an example, the characteristic coefficient is determined through the current survey data. Based on this, the service attribute parameters of various travel modes of the Chengdu-Chongqing Railway Passenger Dedicated Line and the expressway double-track line are set up, Share rate.
