摘要
城市路网系统节点(交叉口)的交通流量预测是城市交叉口宏观规划管理和交通流在路网中高效调度的依据,对其进行合理的预测意义重大.本文基于聚类分析法结合判别分析结果对主要交叉口及待判别交叉口交通流量进行预测,并用实例加以验证说明其实用性.
Traffic volume forecast on urban road network node is foundation of macro- management and efficacious traffic flow guiding. Thus, reasonable forecast is significant. Based on cluster analysis, this paper proposes a method through discriminant approach to forecast traffic volume of main intersections and intersection to judge. Study used by example shows that this method is to handle and more effective.
