论文摘要
在过去时间的价值的研究中，旅行时间的价值和节省旅行时间的价值是在很长一段时间内隐约区分的两个不同概念。本文应用观点理论来讨论不同受访者和不同模型之间旅行时间和节省旅行时间的价值的差异。为此，本文设计了一份针对城市旅行行为的RP-SP问卷，并收集了409 Guangzhou居民的旅行偏好数据。 By introducing potential profiling to capture the effects of heterogeneity between classes, the respondent group is divided into three categories according to its individual socio-economic characteristics such as age, income, educational attainment, etc. After that, the utility function of travelers is established, and the MNL model, MIXL model, S-MNL model, G-MNL model, LCL model and MM-MNL model are selected for the total sample and three types of groups to estimate the时间值。本文强调了VTT和VTT的定义，并提出了一种使用LPA估算VTT和VTT的方法，以识别旅行者的异质性。
In research on the value of past time, the value of travel time and the value of saving travel time are two different concepts that have been vaguely distinguished over an extended period of time. This paper applies the theory of perspectives to discuss differences in the value of travel time and savings in travel time between different respondent groups and under different models. To this end, this paper designs an RP-SP questionnaire for urban travel behaviour, and collects data on the travel preferences of 409 Guangzhou residents. By introducing potential profiling to capture the effects of heterogeneity between classes, the respondent group is divided into three categories according to its individual socio-economic characteristics such as age, income, educational attainment, etc. After that, the utility function of travelers is established, and the MNL model, MIXL model, S-MNL model, G-MNL model, LCL model and MM-MNL model are selected for the total sample and three types of groups to estimate the time value. This paper emphasizes the definitions of VTT and VTTS, and presents a method for estimating VTT and VTTS using LPA to identify traveler heterogeneity.
