恶劣天气和地震、泥石流等地质灾害频发导致大量公路、桥梁等基础设施受损,道路交通事故、危险品运输车辆事故、局部路段交通量大等重大事件也导致公路网出现堵塞现象。据统计,2009年,全国累计发生严重公路阻断事件4000余起,累计导致公路阻断里程达19.45万公里,阻断事件累计持续63万小时。根据交通运输部路网中心的统计,今年上半年共统计到的严重公路突发事件2510起,累计造成11.51万公里的公路阻断,同比分别增长11%和12%。因此,迫切需要建立反应灵敏、运转高效的公路应急管理体系,提高应对各类突发事件的应急处置能力。 Severe weather and earthquakes, debris flows and other geological disasters led to a large number of damaged roads, bridges and other infrastructure, road accidents, dangerous goods transport vehicles accident, large sections of traffic and other major events also led to blockage of the road network. According to statistics, in 2009, there were cumulatively more than 4,000 serious road blockings nationwide, resulting in a total of 194,500 kilometers of road blockings and a total of 630,000 interruptions. According to statistics from the Ministry of Transport Road Network Center, a total of 2510 serious road accidents were recorded in the first half of this year, causing a total of 115,100 km of road blocks, an increase of 11% and 12% respectively year-on-year. Therefore, there is an urgent need to establish a responsive and efficient highway emergency management system and improve emergency response capacity for all kinds of emergencies.
