The purpose of this study is to present the improvement of connection system between traffic information centers for reliable traffic information service. We recognized traffic information error caused by too much time in conjunction between traffic information centers, lack of reliability of traffic information caused by absence of generation time and generation institution of traffic information. We presented minimization methods of connection time, improvement methods of reliability of traffic information and development methods of connection state management system.

선박과 선박간의 사고 위험도를 예측하는 교통정보 생성 기술을 해상교통관제센터에 적용하기에는 위험도 정보의 정확성에 한계가 있다. 또한 대상 해역에 대한 교통 패턴을 파악하는 밀집도 및 혼잡도와 같은 교통정보 생성 기술은 위험 우선순위 선박을 도출하는 것이 불가능하다. 복잡한 교통 패턴을 보이는 해상교통관제 해역에서 위험 선박을 인지하여 관제사의 관제 업무를 지원하기 위해서는 새로운 접근이 필요하다. 본 연구에서는 관제대상해역의 교통 상황을 총체적으로 파악하고 위험 선박을 사전에 인지할 수 있는 교통정보 생성을 위해서 기계학습 기법을 검토하였으며, 기존의 인공지능 한계를 극복하기 위한 딥러닝 프레임워크 도입을 검토하였다. 해상교통관제센터의 이미지, 메시지, 음성 등 다양한 형태의 연속적 자료들을 통합하고 이를 토대로 총체적인 분석을 통해 관제 업무를 지원할 수 있는 교통 상황 인지 정보를 생성할 수 있을 것으로 파악되었다. 빅데이터 기반의 기계학습은 보다 의미 있는 상황 인지 정보를 생성할 수 있기 때문에 이를 위한 관제 센터의 각종 데이터 통합이 필요하다.

최근 빅데이터 기술 개발로 방대한 데이터의 유의미한 분석 및 예측이 용이해졌다. 선박교통관제센터에서는 각종 센서와 다양한 정보를 기반으로 VHF 교신을 통해 선박교통관제를 수행한다. 관제사가 활용하는 레이더, AIS, Port-MIS. 센서 등의 데이터들이 디지털로 저장되고 있으며, 관제사의 VHF 교신내용은 디지털파일로 저장되어 선박교통관제센터의 서버 2개월간 보관된다. 본 논문에서는 관제 결과로 저장되고 있는 관제 로그 데이터를 활용하여 빅데이터를 구성하고 이를 기반으로 유의미한 정보를 생성할 수 있는 방안을 연구하였다.

향후 변화될 해양 4차 산업시대에 대응하고 상호 정보 공유를 위해 외부 시스템과 연계할 수 있는 기반환경 마련이 필요한 바 관제센터에서 수집되는 정보를 활용하기 위해서는 관제정보 관리 및 공유 체계가 필요하다. 하지만 정보의 보존 기간이 짧고 접근에 제약이 많아 기술개발에 활용될 관제 정보의 빅데이터화가 어렵다. 또한 정보를 관제 센터 내 독립적으로 보관하고 있어 연구 개발 목적의 접근이 쉽지 않다. 본 연구에서는 민간 클라우드를 활용한 관제 정보 관리 및 공유 체계 방안을 살펴보았다.

This study set out to developing data exchange standard between roadside device and traffic information center fitted in a domestic environment by applying international standard ISO 15784. First, we defined message basic concept of 'Dialog' and essential elements should be defined to define the standard message for securing system compatibility by reference ISO 14817 and ISO 14827 Part 1. For defining standard message items exchanged between AVI and traffic information center, we formed Working Group under ITS Standards Technical Committee and analyzed data flow for ITS National Architecture, Standard messages of existing standards, and AVI operation messages actually operated on roadside now. So, we extracted 14 functionally needed messages and defined 28 standard messages adopting 'Dialog' concept. In case of the application protocol for data exchange standards, we defined basic requirements for securing interoperability and interchangeability considering domestic environment by analyzing reference standard of ISO 15784.

Road Traffic Authority and National Police Agency is currently managing the "development of an integrated metropolitan traffic information infrastructure" that installs of facilities for a traffic information infrastructures, such as Local Traffic Information Center, UTIS(Urban Traffic Information System), CCTV, VMS and etc. CTIC was established in 2005 to act as an traffic information hub and to provide integrated UTIS traffic information without regional barriers. This study was carried out to seek for solution to improve quality of UTIS traffic information service for the Central Traffic Information Center(CTIC). In this study, the Evaluation index for UTIS traffic information service was developed and the implementation plan was established by using requirement analysis method, case study and AHP(Analytic Hierarchy Process) technique. The Evaluation index consist of 5 fields and 20 index, it make possible evaluation of direct/indirect effect for UTIS traffic information service. In conclusion, It is expected that quality of UTIS traffic information service will be improved by using developed evaluation index and also can be applied for performance evaluation of other traffic information systems.

This paper demonstrates a methodology of integrated operation and management system for intermodal connectivity center (ICC), which is planning to be build up as a large scale public transit facilities for green growth strategy by the national government. The ICC needs to be capable of providing the integrated location based information for the public transit users in terms of collaborating a variety of transit modes and complex facility in a large scale center. Recently, the upcoming information and communication technologies enable to come up with real time information provision on nomadic and portable devices, i.e. smart phones and/or tablet PCs, as what the users actually need to get on demand. In order to provide the public transit users in ICC with the integrated information on their smart phones for example, the integrated operation and management system plays a key role to collect the data utilizing the wireless communication with real time location tracking and to manage them to be effective and operational sources for applicable personalized services. Thus, this paper defines a type of services, subsystems, and relevant technologies for the system integration so called a "Smart Garatagi Service" and shows a filed test demonstration case in the existing airport terminal, Gimpo Domestic.

Ministry of Land, Transport and Maritime Affairs prepared the method to update traffic connection system by amending "National Transport System Efficiency Act(hereinafter Act)". The key is a development of Intermodal Transfer Center. The law and guideline related with Intermodal Transfer Center requires the installation and operation of transfer information guide facility to improve user's convenience. However, there are no sufficient studies that can be used as references for the method to construct transfer support information system related with user's preference. The study performed the research about user's service satisfaction in relation with transfer support information service, which was embodied in model operation process, on the basis of transfer support information system of Intermodal Transfer Center applied to Gimpo Airport. The analysis result about service preference, importance of each supplied information, service satisfaction and consideration for service embodiment can be used as a guideline to embody the user information service of Intermodal Transfer Center. In addition, through CVM, the study estimated and proposed the service valuation of smart intermodal transfer service that provides customized information to cope with user's situation and traffic means operation status among transfer support information service. It is determined that the study will measure the benefit of Intermodal Transfer Center user by using monetary value when smart intermodal transfer service is supplied and provide the ground to expand high-tech transfer information service with high usefulness and convenience.
