基于AIS原始数据的天津港交通流模型

Tianjin Port Traffic Flow Model Based on AIS Raw data

基于OD(Origin and Destination)交通流模型理论,使用大连海事大学动态仿真和控制实验室自主开发的电子海图显示软件与数据库,采用设置断面,处理、分析AIS原始数据,统计船舶通过断面时位置的方法,分析天津港航道船舶交通流状况。利用数理统计知识,初步建立天津港交通流模型,揭示天津港航道船舶交通流的规律并生成模拟交通流。研究结果可以为VTS模拟器的研发以及天津港船舶交通流的管理提供科学依据。

Based on OD（ Origin and Destination） traffic flow model theory,using the electronic chart display software and database independently developed by Dalian Maritime University Dynamic Simulation and Control Laboratory,AIS raw data are processed by setting a section to calculate vessels passing the section,so as to study the traffic flow of Tianjin Port. Making use of mathematical statistics knowledge,the Tianjin Port traffic flow model is preliminarily built to reveal the rules of the traffic flow and generate the simulation traffic flow.The results can be deemed as a pre-research for VTS simulator,and provide scientific basis for traffic flow management of Tianjin Port.
