EVALUATE BENEFITS OF VESSEL TRAFFIC SERVICE SYSTEM IN HAI PHONG PORT AREA

Abstract

The Vessel traffic service (VTS) system plays an increasingly important role in ensuring traffic safety, improving efficiency and protecting the maritime environment. However, the benefits of VTS have not been fully recognized. In addition, previous assessments often have problems such as: difficulty in collecting data for the parameters of the assessment model; those models do not take into account factors such as reducing the frequency of patrols by channel clearing canoes and saving manpower; it is difficult to distinguish clear benefits when using VTS or not using VTS. In this paper, the benefits of VTS in Hai Phong will be calculated according to the main indicators (safety, traffic efficiency, environmental protection and reducing monitoring costs) applying quantitative methods. When calculating the benefits, the base point is taken as the time before the operation of the Hai Phong VTS system with data from the period 2017-2024. According to the results, the greatest contribution is the environmental protection benefit including the reduction of emissions. Through the cost-benefit analysis, the benefit/cost ratio of VTS is up to 4.832, indicating the great benefits from VTS. This result is evidence for the best reference to evaluate the benefits of VTS system and optimize investment in VTS system for seaport areas.
