The invention discloses a highway tunnel traffic situation awareness system and method based radar, and the system comprises a radar monitoring subsystem which comprises radars which are continuouslyarranged in a tunnel at equal intervals, obtains the real-time vehicle information of each lane, and marks a time label, and each radar has unique stake number position information; the network transmission subsystem uploads data acquired by the radar monitoring subsystem to the data analysis subsystem through a network; the data analysis subsystem matches the vehicle information according to thestake number position information of the corresponding radar, and transmits the tunnel traffic information with the time label and the stake number position information to the three-dimensional display subsystem; and the three-dimensional display subsystem displays the tunnel traffic information in a three-dimensional space according to the coordinate position of the stake mark position information. According to the invention, the traffic flow situation is displayed in a three-dimensional manner, the expression effect of the traffic flow and the traffic event is improved, the difficulty of obtaining the tunnel traffic flow situation and the traffic event by monitoring personnel is reduced, and the perception degree of the tunnel road condition is improved.
本发明公开的一种基于雷达的公路隧道交通态势感知系统及方法,包括雷达监测子系统,包括连续等距布置于隧道内的雷达,获取每条车道实时车辆信息,并标记时间标签,每个雷达具有唯一的桩号位置信息;网络传输子系统通过网络将雷达监测子系统采集的数据上传到数据分析子系统;数据分析子系统将车辆信息按照对应雷达的桩号位置信息匹配,并将带有时间标签、桩号位置信息的隧道交通信息传输给三维展示子系统;三维展示子系统根据桩号位置信息的坐标位置将隧道交通信息在三维空间进行显示。本发明解决了利用三维展现车流情况,提升了交通流和交通事件的表现效果,减小了监控人员的获知隧道交通流态势和交通事件的难度,提高了对隧道路况的感知程度。
