摘要
对城市紧急事件交通流的合理诱导与控制是各级交通应急指挥部门必须面临的一项重大挑战。在有线视频安全接入方案的基础上,提出一种基于无线移动视频接入的交通流应急控制策略来诱导紧急事件影响范围内的车流辆。该策略以实时接入事发现场的视频信息为基础,同时结合紧急事件交通流诱导的模糊控制策略,确定了影响范围内道路的信号配时方案,从而在微观层面上实现对路网上拥堵车辆的诱导和控制;同时依据紧急事件事发现场交通流的运行情况,出具了紧急事件应急车辆的信号优先控制模型,以便应急车辆能够快速到达事发现场,从而为影响范围内的交通流与应急车辆提供微观上的控制策略,有助于各级指挥中心制定合理的应急救援措施。该方案已在多地公安省厅试点运行,效果良好。
It is challenging for the traffic emergency department to develop a reasonable guidance and control strategy of traffic flow in ur- ban emergency. In order to guide the vehicle of the traffic emergency incident influence range, a control strategy of traffic flow emergency based on mobile video access is proposed. After monitoring the road emergency scenes, the proposed scheme establishes the signal timing scheme for the road within the scope of influence based on fuzzy control strategy, and presents a signal priority control model of emergen- cy vehicle. On the one hand, these actions propose a microcosmic control strategy for the traffic flow and the emergency vehicle within the scope of influence. On the other band,these actions would be favorable for the traffic emergency department to develop the effective e- mergency rescue measures. Recently, the scheme has been conducted the pilot run in some ministries and agencies, and has achieved good results.
