| 摘 要： | 城市轨道交通乘客出行路径集是否正确,是乘客路径选择估计以及网络客流分布计算的前提和基础.从现有客流分布模型中有效路径选择集问题及OD实际旅行时间聚类特征出发,引入Rodriguez-Laio快速聚类算法,提出基于旅行时间聚类分析的城市轨道交通乘客路径集验证方法.以北京地铁网络为例进行算例分析,结果表明,该方法可以在全网络范围内对路径选择集问题OD作出快速识别及滚动验证,并为以原因分析为导向的现场客流调查与模型修正工作提供重要参考.

| Abstract: | The route choice set plays an important role in estimating passenger route choice and consequently calculating passenger flow distribution on an urban rail transit (URT) network. In terms of the problem of the route choice set in the existing assignment model and the cluster characteristics of actual travel times of URT passengers, a URT route choice set validation method based on travel time cluster analysis was proposed. It was developed on the basis of Rodriguez Laio cluster algorithm. Taking the Beijing subway network for example, it is found that the proposed method can make rapid identification and rolling validation for abnormal OD on the whole network level, and provide important references for the passenger flow survey of cause analysis oriented as well as model modification. |
