中文摘要：
为定量研究局部水域交通流的复杂性,通过解析水上交通流的结构特征,建立一种水上交通流复杂性测度模型.该模型由交通密度因子和交通冲突因子组成,不仅能够有效地反映出船舶之间的相对距离、航迹交叉角和相对速度对水域交通流复杂性的影响,还能揭示所研究水域的交通流复杂度的空间分布规律.以深圳西部海域的水上交通流为例,建立了该海域的水上交通流复杂度模型.经过实例验证,证明了该模型能够客观地反映出水域交通状态的变化特征.
英文摘要：
A model of marine traffic complexity is developed to address the problem of measuring marine traffic flow complexity in terms of its structure.The model,in which the traffic density factor and conflict factors are considered,reflects the traffic complexity and traffic characteristics including the relative distance,speed of ships pair-wise and the intersecting trajectory.The model reveals the spatial distribution regularities of the marine traffic complexity.The simulated data of Shenzhen West Sea are used to verify the model.The verification tests show that the model sensitively and accurately reflects the characteristics of the marine traffic in terms of its complexity.
