【摘要】：随着长江内河桥梁的新建，繁荣了两岸经济的同时也给桥区船舶的航行带来影响。桥区船舶交通流量不断增大，交通流密集水域事故频发，为加强长江桥区河段的安全预警管理，保障船舶安全，，防治水域污染，需对桥区船舶交通特性进行研究和分析。采集武汉段和芜湖段桥区船舶交通数据，应用统计学方法对其进行统计分析和理论研究，有助于从宏观和微观上掌握特定水域内船舶交通的实际状况、基本特征和一般规律。 本文通过研究桥区水域特点，研究桥区航道范围，采用现场统计方式获得大量运行在长江桥区货船的船舶信息，如船长、船舶类型、船速、吃水深度、船间距等船舶交通属性。应用统计学方法分析船舶属性的统计信息，主要拟合船舶船长，船速，船间距的分布规律，并做了船舶交通流航迹仿真分析，可为其他船舶经过桥区时提供一定的参考。 本文的主要研究工作包括如下三个方面： （1）对比现有长江桥区航道各种船舶交通流采集技术和调查方法，选取LS-1测速雷达采集武汉和芜湖桥区河段过桥船舶进行航道船舶实时交通流数据，并整理分析。 （2）建立交通流数据模型，根据船舶行为特征，对船舶类型、船舶长度、船舶速度、船舶间距数据用统计学方法分析，通过直方图和拟合曲线，得出其分布规律。综合考虑航道尺度、船舶到达不均衡系数、设计小时系数和运货量不平衡等系数对交通流进行计算。 （3）桥区航道船舶交通流仿真模型的建立。生成合理的船舶模型，包括船舶交通流，船舶节点。生成合理的航道模型，包括航道和航行轨迹。根据船舶交通流生成算法进行航迹仿真实验验证。 通过本文的研究，掌握了长江桥区船舶交通的基本规律，为后续的研究应用和完善奠定了一定的基础。
[Abstract]:With the construction of the Yangtze River Bridge, the economic prosperity of both sides of the Yangtze River has also affected the navigation of ships in the bridge area. In order to strengthen the safety early warning management of Yangtze River bridge section, to protect ship safety and prevent water pollution, it is necessary to study and analyze the characteristics of ship traffic in bridge area. Collecting ship traffic data from Wuhan section and Wuhu section, and applying statistical method to statistical analysis and theoretical study, it is helpful to grasp the actual situation, basic characteristics and general rules of ship traffic in a given water area from macroscopic and microscopic aspects. In this paper, the characteristics of the water area of the bridge area and the range of the waterway of the bridge area are studied, and a large number of vessel information such as captain, ship type, ship speed, draught depth, distance between ships and so on are obtained by field statistics. The statistical method is used to analyze the statistical information of ship attributes, which mainly fits the distribution law of ship captain, ship speed and ship spacing, and makes the simulation analysis of ship traffic flow path, which can provide some reference for other ships to cross the bridge area. The main research work of this paper includes the following three aspects: (1) comparing various vessel traffic flow acquisition techniques and investigation methods in the waterway of the Yangtze River Bridge area, The LS-1 velocity radar is selected to collect the real-time traffic flow data of the vessels crossing the river section in Wuhan and Wuhu Bridge area, and the traffic flow data model is established. (2) according to the characteristics of the ship's behavior, the ship type and ship length are analyzed. The data of ship speed and distance are analyzed by statistical method. The distribution law is obtained by histogram and fitting curve. Considering the channel scale, the ship arrival unbalance coefficient, the design hour coefficient and the cargo quantity unbalance coefficient, the traffic flow is calculated. (3) the simulation model of the ship traffic flow in the waterway of the bridge area is established. Generate a reasonable ship model, including ship traffic flow, ship nodes. Generate reasonable waterway models, including waterways and navigation tracks. According to the ship traffic flow generation algorithm, the track simulation experiment is carried out. Through the research of this paper, we have mastered the basic law of ship traffic in the Yangtze River Bridge area, and laid a certain foundation for the further research, application and perfection.
