摘要: 适宜的时段选取能促进交通影响评价(TIA)的有效性. 本文利用聚类分析方法,将建筑项目进行分类,根据各类之间的相似性,确定同类项目的出行高峰时段,并最终确定项目研究时段的选取范围. 同时,基于北京市一些典型居住项目的出行调查数据,按照项目的早、晚高峰进行聚类,最终以区位因素确定了居住项目的早、晚高峰分类结果;结合分类结果、项目实际调查数据以及北京市外部路网的高峰时段分布情况,本文给出了北京市各类型居住项目交通影响评价中研究时段的选取范围.

关键词: 聚类分析, 交通影响评价(TIA), 时段选取, 高峰小时

Abstract: This paper presents the methods of selecting studied period of traffic impact analysis based on the cluster analysis, and puts forward the concept for the construction projects classification. It determines the analysis period according to the similarity between the same categories. Meanwhile, with the residential project sampling survey data of continuous traffic volume in Beijing, the paper clusters all the samples and finally obtains the classified result according to the factor of location. With basic investigated data and consideration of the peak period of the outside network, this paper proposes the analysis period of residential projects in Beijing. It provides reference for consulting organization in TIA work.

Key words: cluster analysis, traffic impact analysis (TIA), period selection, peak hours
