本文通过对常用交通检测设备性能分析,提出了以视频和微波车检器作为交通事件检测的主要设备,并对检测的交通参数提出了具体要求;在线性交通流的假设下,以检测出交通事件为目标,提出了检测器的布设原则及优化布设的数学模型,并以郑州机场高速为对象,采用Transmodeler仿真给出了检测器布设的最佳布设间距;提出了以微波车检数据与基于视频运动轨迹分析相融合的交通事件自动检测和定位方法,根据实际情况给出了多种融合方案。
Based on the analysis of the performance of commonly used traffic detection equipment, this paper proposes a video and microwave detector as the main equipment for traffic accident detection, and puts forward specific requirements for traffic parameters detected. Under the assumption of linear traffic flow, traffic detection This paper puts forward the principles of the detector layout and the mathematical model of the optimal layout. Taking the Zhengzhou Airport Expressway as an example, the optimal layout distance of the detector is given by the Transmodeler simulation. Video motion trajectory analysis of traffic accident automatic detection and location methods, according to the actual situation is given a variety of fusion programs.
