基于相似聚类分析的交叉口交通流量预测

Forecast of Traffic Flow Based on Analysis of Similarity and Clustering in the Urban Crossing

从城市道路交叉口交通流量的特征出发,采用数理统计学相关系数和聚类的方法,利用安装检测器交叉口检测出来的交通流量进行相似分析和聚类分析,对无检测装置的交叉口进行判别、归类,并对其交通流量的预测,可较好实现城市路网节点交通流量的预测和交叉口的宏观管理.

Based on the characteristic of Urban Crossing＇s traffic flow and with the method of correlation coefficient and Clustering Analysis in mathematical statistics , this paper analyzes the similarity and clustering of the data measured by fitting apparatus in the urban crossing. It also discriminates and classifies the Urban Crossing without fitting apparatus and forecasts the traffic flow of the urban crossing without fitting apparatus.
