Extraction Method for Traffic Information of Regional Road Network
-
摘要: 为提取区域路网交通信息,基于物元分析理论提出了道路交通状态的判别方法.将交通状态的判别结果作为决策属性,综合考虑道路等级、时间及交通参数,构造区域路网的交通流特征信息表.用粗糙集方法提取交通流特征.用区域路网交通流特征提取示例验证了提出的方法的有效性.该方法可实际应用于在线交通状态判别和历史数据库的交通信息提取.Abstract: To extract the traffic information of regional road networks,a method was proposed to identify traffic states using the matter-element analysis theory.In the method,traffic states are taken as decision attributes,a characteristic information table of traffic flows is constructed based on road grades,time and traffic parameters,and the traffic flow characteristics are extracted using the rough set theory.Numerical results of a case study verifies the effectiveness of the proposed method.The proposed mothod applys to traffic state analysis on-line and to extraction of traffic information from historical databases.
