基于Gumbel分布的非集计模型研究

The Study of Disaggregate Model Based on Gumbel Distribution

如何充分运用已建成停车换乘设施的能力,又不会由于交通需求太大在交通换乘点产生交通拥挤是交通运输领域研究的一项重点。利用非集计模型对出行者选择行为进行分析可以有效确定换乘点的分担率。概率论中,Gumbel分布是一种在交通运输领域较为罕见的频率分布函数,文章将重点运用Gumbel分布对出行者在换乘设施的选择行为模型进行公式推导及论证。

How to make full use of the existing park ride（ PR） facilities while avoiding congestion caused by a high demand of PR activities at these facilities proves to be a challenge to transportation research. Disaggregate model which is used to analyze traveler choice behavior can effectively identify the share rate of change point. In probability theory, the Gumbel distribution is a relatively rare frequency distribution function in the transportation field, this article will focus on formula deduction and demonstration using the Gumbel distribution on traveler＇s choice behavior model of transfer facility.
