摘要
现代检测理论与技术 ,完全有能力采集到完整的微观交通流数据 ,即断面或区域车辆序列信息 ,包括每一辆车的车辆属性、位置属性和运动属性。微观交通流信息对于通行能力分析、智能交通控制、异常交通状态识别、微观交通流特性研究、宏观交通流行为理解以及实验交通工程学的发展 ,具有重要的意义。视频检测技术在微观交通流信息采集和研究中具有无可替代的作用。文章系统分析和完整描述了断面和区域两类微观交通流信息 。
Modern sensing theories and technologies should have the potentialities to collect complete microscopic traffic flow data, including individual vehicle properties, location and movement properties in vehicle series crossing the section or area of view. Microscopic traffic flow data are essential for capacity analysis, intelligent traffic control, abnormal traffic state recognition, microscopic traffic flow characteristics study, macroscopic traffic phenomenon understanding, and Experimental Traffic Engineering (ETE) development. Video detection technologies are significant for microscopic traffic flow data collection and research. This paper systematically analyzes microscopic traffic flow data and gives the description models, and introduces a microscopic traffic flow video data collection system developed based on it.
