摘要
为保障内河桥区水域船舶通航的安全性,提高通行效率,以长江武汉大桥水域为研究对象,基于船舶自动识别系统(Automatic Identification System,AIS)信息对该水域的船舶行为特征进行分析。利用基于欧式距离与最小方差法的聚类方法分析,认为过桥船舶可依据主机功率的不同进行划分。在长江船舶定线制的框架下,结合栅格法与蚁群算法建立武汉大桥水域的航道规划模型,对基于船舶行为特征的船舶航线进行优化。仿真结果表明:该方法在保证船舶安全、高效航行的前提下,能有效帮助海事管理部门对武汉大桥水域船舶航线进行优化。
The AIS（ Automatic Identification System） data collected from Wuhan Yangtze River bridge waterway is processed to find the behavior characteristics of ships in the area. The clustering analysis is conducted based on the Euclidean distance and the minimum variance. The analysis shows that the passing inland ships can be categorized according to their main engine power. In the framework of the traffic separation scheme in the Yangtze River,a route-planning model for ships with differing ship behavior characteristics is proposed based on the grid method and the ant colony optimization algorithm.Simulations show that the proposed method can effectively optimize the ship route in the Wuhan Yangtze River bridge waterway area,which may help Maritime Safety Administrations to improve the ship route scheme.
