The Research Of Traffic Flow Model In VTS Simulator

The purpose of VTS personnel training is to let trainee get enough qualification. VTS simulator plays an important role in the personnel training. The exercise can improve the technology level and management capability of the person, so it can enhance the safety of shipping traffic, increase the efficiency of shipping transportation and ensure the ship safety at sea.In the VTS simulator, the setting of the traffic flow has become a major auxiliary means in the human-computer interaction for the trainees. The fidelity of traffic flow simulation has a great effect on the operation ability and emergency response ability of the VTS trainees, so the traffic flow with high realism is an important part of the study of VTS simulator. This thesis builds a traffic flow model which is in accordance with the practices of Dalian port based on the study and analysis of the theory of traffic model. The main contents in the thesis are as follows:1. Based on the actual data of ship entering and leaving Dalian port, we get the statistics using the investigated method based on the information of AIS and find the distribution law of traffic, the law of interval between two vessels, the generation law of traffic flow, the service law of anchorage and berthing.2. Based on the statistical data of Dalian port, this thesis builds the models of traffic flow and integrates the models with the simulation sofware. The models included the traffic flow model from origin to destination, the distribution model of seaway, the generation model of traffic flow, the model of vessel collision avoidance, the service model of anchorage and berthing.3. This thesis builds a traffic flow model by using electronic chart as a platform.By comparing and analyzing simulation result with actual data, the models are verified preliminarily.
