智慧高速路侧感知设备优化布设方法研究

Research on optimal layout method of perceptive equipment on intelligent highway side

为了研究智慧高速路侧设备优化布设问题、合理布设方案,在SUMO和OMNET++双向耦合仿真平台中模拟出高速公路基本路段场景以及发生异常事件的高速公路场景,采用根据交通流参数变化来判定事件是否发生的事件间接检测算法以及路侧检测设备检测范围内直接感知异常事件相结合的方法,来研究考虑检测范围视频检测器布设方案对异常事件的检测效益,并综合考虑布设成本,通过仿真实验得到考虑检测范围视频检测器布设方案的合理布设间距为300 m。

In order to study the optimization layout of intelligent expressway side equipment and reasonable layout scheme,the basic section scenes of expressway and the expressway scenes with abnormal events were simulated in SUMO and OMNET++bidirectional coupling simulation platform.The indirect event detection algorithm,which determines whether an event occurs according to the change of traffic flow parameters,and the method of directly perceiving abnormal events within the detection range of roadside detection equipment are adopted to study the detection benefits of abnormal events by considering the deployment scheme of video detector within the detection range,and considering the cost of installation comprehensively.Through the simulation experiment,the reasonable distance of 300 m is obtained for the video detector layout scheme considering the detection range.
