ANALYSIS OF MINIMUM SPEED CONTROL EFFECT USING QUEUE MODEL FOCUSING ON BUSAN PORT

摘要

VTS aims to increase the efficiency of maritime traffic in two ways. The first is a decrease in marine accidents, and the second is an increase in the utilization rate of infrastructure such as waterways and port facilities. This means that, if safety is guaranteed, efficiency must also be considered in the VTS. The purpose of this study is to quantitatively analyze the effects of speed regulation under safe conditions for an efficient use of waterways. A model was developed using a queue approach, and the effect of the waiting time according to the minimum speed proposal was analyzed through a simulation. The simulation results showed a maximum reduction in congestion of 6.1% occurred when setting the minimum speed to 6 knots. The capacity of the routes was also analyzed, and the results indicate that 2.5 ships can have sufficient time to pass through the waterway at a safe distance.
