Abstract: Vessel Traffic Service (VTS) is a complicated facility system to enhance the safety level of waterway vessel traffic, improve traffic efficiency and protect the water area environment. The principle of its role is to use communication facilities such as radar stations, automatic ship identification system base stations, VHF calls and shipboard terminals to realize the monitoring of ships in the supervised water area and to provide ships with the navigation safety information required for navigation to ensure the safety of vessel navigation. Since its introduction into China, it has been playing an important role in guaranteeing vessel traffic safety, improving efficiency of waterway vessel traffic.
As an important tool for the maritime department to achieve waterway traffic safety management, its construction and use can effectively maintain the stability of the waterway traffic safety situation, improve the efficiency of waterway navigation, and promote the good and rapid development of the shipping economy. In accordance with the general requirements of China’s construction of a strong transportation country and a strong maritime country, as well as the Ministry of Transportation and Communications Maritime Bureau to promote the construction of ‘land, sea, air and sky’ integrated waterway transportation safety assurance system, and at the same time to meet the new waterway supervision needs caused by the large-scale ship and the growing flow of ship traffic, the competent maritime authorities need to build a large number of VTS systems to meet the regulatory needs, to enhance the supervision, management, emergency security capabilities and abilities of China’s jurisdictional water area, international water area. Among them, VTS radar station, as the core component of VTS system, plays a crucial role in monitoring the waterway under navigation, and its location deployment and radar configuration affect the function of the whole system, so it is necessary to study the location selection and radar configuration of VTS radar station.
In view of the current VTS radar station location optimization study, which does not consider the actual number of proposed radar stations and the attenuation of radar radio wave propagation in the air, the attenuation function measurement mechanism is introduced. And the bi-objective location optimization model of VTS radar station is proposed based on the idea of gradual coverage in terms of station construction cost and coverage rate with consideration of radar configuration, and the adaptive weight particle swarm algorithm is designed to solve the model. The results show that the final solution can achieve the optimal location program under the condition of satisfying the constraints, which provides a solution idea for the location optimization of VTS radar stations.
However, the location selection of VTS radar stations in the actual environment is a systematic project that requires consideration of many factors, so the location optimization can be decided from several differential factors, such as the density of ship navigation routes, etc. Meanwhile, the algorithm used in this paper can be further improved to improve the accuracy and scientificity of the solution method.
