用户异质下铁路交通通勤者出行成本

The Travel Cost of Rail Commuters under Heterogeneous Users

摘要: 在铁路交通出行系统中，首先在考虑出发时间选择的基础上，通勤者按照早到惩罚与体触拥挤参数的差异被分成两组，研究了两组通勤者乘坐地铁时的出行行为，并由此推导出两组异质性用户乘坐铁路时的出行成本。其次，研究了双站点下两组异质性用户的出行行为，并由此推导出双站点下异质性用户乘坐铁路时的出行成本。研究表明，在考虑异质性差异的存在时，通勤者的出行成本相比同质性假设下的出行成本更低，且异质性差异越大成本将会越低，并且随着通勤人数的增长，异质性因素对出行成本的影响也将变得更显著。最后，算例的结果也表明了在进行铁路出行成本计算时，异质性因素需要被关注。

Abstract: In the railway transportation system, first of all, on the basis of considering the choice of departure time, commuters are divided into two groups according to the difference in the parameters of early arrival penalty and physical contact congestion. The travel behavior of the two groups of commuters when riding the subway is studied. This derives the travel costs of two groups of heterogeneous users when riding the railway. Secondly, the travel behavior of two groups of heterogeneous users under dual-sites is studied, and the travel costs of heterogeneous users under dual-sites are derived from this. Studies have shown that when considering the existence of heterogeneous differences, the travel cost of commuters is lower than the travel cost under the homogeneity assumption, and the greater the heterogeneity, the lower the cost, and as the number of commuters increases growth, the impact of heterogeneous factors on travel costs will also become more significant. Finally, the results of the calculation example also show that the heterogeneity factors need to be paid attention to when calculating the railway travel cost.
