1、http:/ 留学生论文专业定制代写网站留学生Essay写作船舶交通管理系统(VTMS)Literature ReviewThe aim of this chapter is to capture the main idea of the research in depth and provide a review on literature related to the study and go through the ideas of various authors towards the relevancy of the study and establish the need for
2、the research.2.1 Evolution Vessel Traffic Management SystemA vessel traffic management system(VTMS)is a nautical vessel movement observing system established by harbor or port authorities.According to TRANSAS(2014)the VTMS system utilizes information collected by advanced sensors,for example,radar,A
3、IS,closed-circuit television(CCTV),Meteo-Hydro and other electronic object detection systems.The primary purpose of VTMS is to improve the safety and efficiency of navigation,improve features of port services,protection of life at sea and the safeguard marine environment.In 1946 a demonstration was
4、done in order to identify the helpfulness of coast based radar system in Liverpool.The initial effort in developing harbour controlled radar was done by establishing a system at the end of Victoria Pier,Douglas,Isle of Man in 1948.(Hughes,2009)With the rapid growth of marine industry marine safety a
5、nd efficient navigation has been addressed as one of the issues that have major consideration.Different methods for improving the marine safety have been developed the past few decades.Some of them can be stated as radio-communications,navigation rules,electronic chart systems and identification sys
6、tems.(Goralski,Ray,&Gold,2011)Goralski et al.(2011)further describes that most recent technological developments in improving vessel traffic management includes radar,electronic charting like Electronic Chart Display Information Systems,(ECDIS),vessel traffic control and management(VTMS)and automati
7、c identification system(AIS)and communication.Several sources of data are combined from sensors such as GPS,radar and AIS in order to improve the vessel traffic monitoring.The final objective of this is offer more precise understanding of the navigational situations.Many developed countries utilize
8、the services of highly sophisticated VTMS.The Port of London is one of the UKs busiest ports utilize an exceptionally advanced VTMS.In this VTMS the data from radars are associated with a mass of other data inside a very advanced computer system.This gives an ongoing picture and a thorough record of
9、 all developments at Port of London.(Goldman,2011)2.2 Vessel Traffic Management Systems in Commercial SettingAs described by Goralski,Ray,&Gold,(2011)many researchers have presented theories of developing an efficient vessel monitoring systems.The need for diminishing human error and decreasing the
10、number and danger of accidents at sea is a need to be addressed.Developing such system to be used in real-time situations is a challenging task.Not much research has been done in this area.The worlds first three dimensional ECDIS prototype was demonstrated in Brest in 2007.This was a research led by
11、 Dr.Rafal Goralski and his team.Its possible to incorporate data from many sensors around a port to produce a real time three dimensional traffic management visualization tool.(Goralski,Ray,&Gold,2011)As stated by Goralski,Ray,&Gold,(2011)an interface has been developed and presently being trialed i
12、n the Port of Milford Haven.This system is used in real-time for navigation observing and control.The system is considered to be the first commercial operation of a 3D VTS.Transas Marine Limited and GeoVS Limited offer 3D vessel traffic monitoring solutions.Transas Group is a worldwide pioneer in ma
13、rine navigation systems.Transas presented its initial 3D vessel activity monitoring system to the business in 2008.This system gives most extreme backing to VTS administrators.(TRANSAS,2011).Sri Lankas first home-developed vessel movement administration system was the result of investigation led by
14、the modeling and simulation group of University of Colombo,School of Computing.The system includes two dimensional and three dimensional views of the harbor.The three dimensional VTMS was established at the Colombo-South harbor in 5th August 2013.(UCSC,2014)2.3 Need for more improved Vessel Traffic
15、Management SystemThe commercial 3D VTMS that were mentioned above are closed proprietary and extremely expensive solutions.This fact raised the need to implement a novel vessel traffic monitoring solution.The modeling and simulation group of University of Colombo,School of Computing developed the Sr
16、i Lankas first home-developed vessel movement administration system.This proposed and developed solution is entirely based on the free and open source structures(Sandaruwan,et al.2013).There are limitations of the existing solution.In the existing solution,real-time movements of the ships can be visualized.However in the existing solution the path of a moving ship is not continuous.Goldman(201
