摘要
针对长江干线水上交通事故频发的状况,分析长江干线水上交通事故黑点特征,为水上交通安全监管与船舶航行决策提供参考。长江海事局辖区2006—2010年的水上交通事故类型主要有碰撞、搁浅和触礁等3种,分别多发于长江上游、中游及下游。利用DBSCAN算法提取长江干线水上交通事故的15个黑点段,结合实际通航环境条件分别对各个典型的事故黑点段事故特征和事故原因进行分析,分析结果与实际情况相吻合,证明采用黑点分析方法分析长江干线水上交通事故的分布规律是可行的,可为制定水上交通安全管理措施提供理论依据。
With the growing of both the number and the size of inland water ships,the risk of maritime accidents on the Yangtze River has been increasing.The analysis of the black-spots of the maritime accidents of the Yangtze River can assist in the marine traffic safety supervision and navigation decision-making.The data about the accidents within the period from2006 to 2010 are received from the Yangtze River Maritime Safety Administration.The collision,stranding and grounding are investigated as the three main accident types.The data show that the main accident types are different on different regions of the Yangtze River,grounding for upper region,stranding for middle region,and collision for lower region.The DBSCAN algorithm is used and 15 black-spots of maritime accidents are extracted.In accordance with the actual navigation environment conditions,the characteristics of each typical accident black-spot are analyzed and the results show that this analysis method is practical and effective.
