分析了小长假铁路客流的行成原因，从出行者特征和出行目的两方面总结了客流影响因素。以客票历史数据为依据，从日发送量、乘车里程等级、席别等级等方面分析了小长假铁路客流波动趋势。定义小长假客流波动系数，根据小长假客流的变化趋势特点，提出用基于波动趋势的客流时间序列聚类方法进行小长假客流规律的研究。并对聚类过程中小长假时间序列的构建、表示方法、特征值提取及聚类步骤进行了详细描述。
分析瞭小長假鐵路客流的行成原因，從齣行者特徵和齣行目的兩方麵總結瞭客流影響因素。以客票歷史數據為依據，從日髮送量、乘車裏程等級、席彆等級等方麵分析瞭小長假鐵路客流波動趨勢。定義小長假客流波動繫數，根據小長假客流的變化趨勢特點，提齣用基于波動趨勢的客流時間序列聚類方法進行小長假客流規律的研究。併對聚類過程中小長假時間序列的構建、錶示方法、特徵值提取及聚類步驟進行瞭詳細描述。

The paper analyzed the causes of the railway passenger flow in the three-day holiday, summarized the factors of the railway passenger flow from the characteristics about passengers and travel purposes, based on the historical tickets data, analyzed the lfuctuation characteristics of passenger lfow in three-day holiday from transport volume, the grade of the board distance, the grade of the seat type, etc, deifned the three-day holiday passenger lfow lfuctuation coefifcient and based on a small holiday passenger trends, proposed a clustering method of time series to study the regular pattern of passenger lfow in the three-day holiday and made detailed descriptions about the building of time series of the three-day holiday and its representations, eigenvalue extraction and clustering step.
