多船协同环境下船舶交通流建模及仿真研究

船舶交通系统仿真是再现船舶交通运行规律，进行船舶交通系统规划、管理和控制优化的重要实验手段和工具。随着船舶交通量的日益增多、船种和船型构成的改变、航线增多、航道拓宽，这些都改变了交通流场的分布和交通流的运行方式，对已有船舶交通仿真理论与技术提出了全新的挑战。针对已有研究中存在的问题，本项目对船舶交通系统仿真中的船舶交通流模型建模、多船协同船舶行为模型及仿真实现关键问题进行深入研究。具体包括：（1）环境解析及构建，重点分析通航环境信息种类和内容对船舶行为规则和交通流特性的影响机制；（2）船舶交通流模型研究，重点研究船舶领域模型和基于元胞自动机的船舶跟驰模型；（3）多船协同船舶行为模型研究，从理论分析和实验分析两个角度，应用多智能体技术对多船协同船舶行为模型进行研究；（4）船舶交通流仿真实现，应用高层体系结构理论将交通流模型、仿真环境及通讯仿真进行有机整合。

Vessel Traffic Systems Simulation can describe and re-appear the running patterns of vessel traffic flow, which are the importation tools and laboratory facilities for planning, management and control of vessel traffic systems. It was changed by the increasing of traffic volume, ship’s type and form, navigation course and the beam of the channel, such as the temporal and spatial distribution of traffic flow. All these changes put forward new challenge to the existing vessel traffic simulation theory and technology. Aiming at the problems existing in the study, the project will perform further researches on the key problems of vessel traffic system simulation, such as vessel movement and behavior model, traffic flow model and simulation realization. Research work include: (1) Navigational environment analyzing and building, focus on analyzing the types and content of environmental information and its influence mechanism on ships behavior rules and traffic flow characteristics. (2) Traffic flow model research focus on ship domain model and following model based on cellular automata. (3) Research on the ship behavior model under the interaction and cooperation of multi-vessels based on Multi-Agent System from theoretical analysis and experimental analysis. (4) Research on the method of traffic simulation realization， the theory of high level architecture is applied to integrate three simulation part including simulation environment model, traffic flow simulation model and communication simulation model.
