The Ministry of Oceans and Fisheries is providing maritime safety services through the operation of the Korean e-Navigation service, and research is continuously needed to improve reliability and quality to secure the competitiveness of the system. In order to secure such competitiveness, we presented the basic design for the big-data maritime information gateway system for minimizes thereal-time operation impact of the Korean e-Navigation service, and a theoretical hardware structure diagram including pseudonymization procedures to implement the overall system and solve privacy security issues. However, the proposed structure diagram and design include only the overall concept, to link real-time maritime information, required detailed privacy security method to satisfy the Privacy Act of the Republic of Korea. To solve this problem, this study will identify factors to violate the Privacy Act within the real-time maritime information(privacy of shipowner, shipping company, captain, navigator, fisherman, etc.) linked by the big-data maritime information gateway system, and research the method to link the secured information to other institutions by encrypting identified the factors.

The operational design domain (ODD) of autonomous vehicles needs to be expanded on highways and urban roads in light of the substantial commercialization of Level 3 autonomous vehicles. Therefore, this study developed a specific infrastructure autonomous vehicle-based cooperative driving service to ensure the driving safety of autonomous vehicles on city roads. The traffic operation efficiency, safety evaluation, and core evaluation indices for each service were selected and analyzed to study the effect of each service. The result of the analysis confirmed that the traffic operation efficiency and safety of autonomous vehicles were improved through the V2X communication-based autonomous cooperative driving service. On the whole, the significance of this study is in deriving the effect of the autonomous cooperative driving service based on V2X communication on urban roads with interrupting traffic flow.

In order to reduce maritime accidents and promote maritime safety and the happiness of the sea people, the Ministry of Oceans and Fisheries has been providing Intelligent Maritime Traffic Information services to the public from the end of January 2021. Various information is generated and collected through this service, and research and development is underway to develop and verify a service algorithm by applying the collected information to data science to realize a safer and more efficient intelligent maritime traffic information service. In order to develop and implement this, a data pipeline system that connects the collected and stored data and can access, use, and store data from multiple systems smoothly is required. Therefore, in this study, a data pipeline that can be used in various systems such as a datascience based service algorithm development environment and an intelligent maritime transportation service test-bed was designed.

C-ITS is an intelligent transportation system that can improve transportation convenience and traffic safety by collecting, managing, and providing traffic information between components such as vehicles, road infrastructure, drivers, and pedestrians. In Korea, road infrastructure is being built across the country through the C-ITS project, and various services such as real-time traffic information provision and bus operation management are provided. However, the current state-of-the-art road infrastructure and information linkage system are insufficient to build C-ITS. In this paper, considering the continuity of time in various spatial aspects, we proposed a group-type network-based traffic situation recognition system that can recognize traffic flows and unexpected accidents through information linkage between traffic infrastructures. It is expected that the proposed system can primarily respond to accident detection and warning in the field, and can be utilized as more diverse traffic information services through information linkage with other systems.

A transportation problem is a serious theme to be solved urgently in the motor era of 20 million vehicles. Recently ITS has been introduced to optimize the efficiency of the current roads, because a excess budget and a long term construction are necessary to build new roads. In this paper an outline and major systems of ITS for Ulsan metropolitan city are presented.

국가적인 지능형 교통시스템(Intelligent Transport System: ITS) 체계에 있어서 단거리전용통신(Dedicated Short Range Communication: DSRC)은 중요한 부분이다. DSRC의 응용부분은 여러분야에 걸쳐 있으며 본 고에서는 자동통행요금징수(Electronic Toll Collection: ETC)의 표준화 동향에 대하여 기술하고자 한다. 그러나 많은 상반되는 자동통행요금징수의 개발로 인하여 에어 인터페이스의 표준화가 어려움에 있다. 본 고에서는 미국 교통부의 지원하에 IEEE(Institute of Electrical and Electronics Engineers)와 ASTM (American Society of Testing and Materials)에 의해 개발되어진 ETC 시스템의 에어 인터페이스 표준들의 현황에 대하여 기술하고 국내의 ETC 시스템의 에어 인터페이스 표준화 동향에 대하여도 기술하고자 한다.

지능형 교통 시스템의 주요 인프라 중 하나인 VANET 은 차량과 인프라 간의 통신을 통해 교통을 예측함으로써 도로 상에서의 안전을 보장한다. VANET 은 모든 노드가 네트워크에 가입할 수 있는 개방형 네트워크이기 때문에 개인 정보 보호가 주된 관심사이다. 분산형 신뢰 관리 시스템은 차량 네트워크에서 수신된 메시지가 신뢰할 수 있는 지에 대한 여부를 결정함으로써, 악의적인 공격자로부터 차량을 지킬 수 있다. 분산형 k-익명성 체계와 블록체인을 결합한 신뢰 관리 시스템은 주변 차량들과 협력하여 익명의 은폐 영역을 구축한다. 본 논문에서는 블록체인을 적용한 분산형 신뢰 관리 시스템을 통해 차량의 위치 정보를 보호하는 최근 연구들을 살펴본 뒤에 향후 발전 방향에 대해 논하도록 하겠다.
