对交通紧急事件事发现场的实时性把控及紧急疏散处理在应急指挥系统中是至关重要的。文中提出一种基于视频安全接入的道路紧急事件响应机制来解决交通紧急事件的迫切性及所造成的治安风险。该方案以实时导入事发现场监控资源为基础，确定交通紧急事件的影响范围，出具动态交通分配的路网应急疏散模型，为影响范围内的车辆提出宏观上的诱导策略，有助于指挥系统制定有效的交通流诱导与控制策略。该方案已在某公安省厅进行试点运行，取得了较好的效果。%The real-time traffic emergency control and the emergency evacuation method is crucial to the emergency command system. In order to handle the traffic emergency which has a risk causing security problems,propose a response mechanism of road emergency based on video security access in this paper. After monitoring the road emergency scenes,the proposed scheme confirms the traffic emergency incident influence range,and presents a traffic network evacuation model of the dynamic traffic assignment. Macroscopically,these actions would be favorable for the command system to develop the effective traffic flow guidance and control strategy. Recently,the mechanism has been conducted a pilot run in some ministries and agencies,and has achieved good results.
