船舶交通系统模拟技术的开发与研究

Study and Development of Marine Traffic System Simulation Technique

概述已研发的船舶交通系统模拟仿真技术及其软件包,内容包括船舶交通的数据搜集、数据库建立、系统建模、系统模拟及避碰模型和应用等,并在船舶交通系统建模的基础上,提出一种新的基于航路的船舶交通系统模拟方法,它可将船舶交通实态观测所得数据通过计算机处理确定航路型状。该方法考虑了船舶交通的随机性,可任意修改航路,使模拟结果更加符合客观实际。系统可输出船舶交通密度图、航迹图、门线图以及各种船舶的交通参数。以大连港为例,通过各航道段水域的观测和研究,验证了模拟模型的可信性。

The developed simulation technique of marine traffic system and its software package are introduced, which includes data collection, database establishment, system modeling and ship anti- collision model and application etc. Based on modeling the marine traffic system, a new route--based simulation method of marine traffic system is presented. This method can determine route geometry with computer processing measured actual observation data. This method takes random nature of marine traffic into account and can correct ship route arbitrarily so as to make simulation results tally with actual situation well. This technique has been used to the safety assessment and demonstration of many harbor＇s marine traffics in China. It can output the figures of marine traffic density, traces, gate lines and parameters of marine traffic. This simulation model is proved in different channel parts of Dalian harbor.
