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.

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.

Developing countries and small local governments face financial constraints, limiting the adoption of their own bus information systems. However, despite poor social infrastructure and low income levels, developing countries have a high smartphone penetration rate, and the distribution and usage of online content and social media are widespread. Smartphones, equipped with GPS sensors, cameras, and other location-based information collection capabilities, can replace expensive on-site terminals. This study aims to replace expensive on-site terminals with smartphones, develop a center system based on cloud servers, and establish an extensible Open BIS (Bus Information System) service and platform that can be applied anywhere. The goal is to formulate a business model in the process.

This research aims to enhance the security and safety of bicycle facilities by utilizing convergence technology of ubiquitous sensor network in the transportation system. To achieve the aim, U-bike system has developed by utilizing sensor network technology, and the serviceability and safety function of public facilities in the system have enhanced. This research also presents a plan for the construction of U-bike using ubiquitous sensor network and safety infrastructure of facilities by analyzing bicycle traffic reports and characteristics of service through studying the literature on the security of bicycles and the safety of facilities on bicycle lanes. The result of this research will contribute to the enhancement of safety function of bicycle lanes and facilities around National 4 major rivers bicycle lanes in the future.

In the transportation sector, reducing total vehicle mileage and passenger vehicle traffic are proposed as strategies to achieve carbon neutrality. To achieve this, MaaS services must be actively promoted with the goal of revitalizing public transportation. In order to promote MaaS, individual movement data is required, such as the individual's means of movement, route, and conversion of the individual's means of use. However, in Korea, there are legal limitations in collecting and utilizing data on individual movements. As the right to request transmission of personal information was newly established in the revised Personal Information Protection Act in 2023, a law was established to collect and utilize data on individual movements. However, enforcement ordinance, detailed rules, instructions, guidelines must be prepared, and the standardization of data format and transmission system for collecting my data needs to take precedence.

인구 및 차량 증가에 따라 날로 심각해지는 교통문제를 해결하기 위해서는 도로를 건설하는 방법만으로는 한계가 있음을 인식하여 새로운 도로의 건설보다는 도로의 교통효율을 높이고 안전성을 확보하는 것이 더욱 중요한 문제로 대두됨에 따라 저비용 고효율의 교통관리방안인 지능형교통체계(ITS)를 추진하였다. 이에 국가기간망인 국도의 ITS 구성과 차량검지기(VDS), 차량번호인식장비(AVI), 폐쇄회로텔레비전(CCTV), 도로전광표지(VMS) 등 주요장비의 구성을 통한 국도 ITS를 이해하고, 국도 ITS 구축 현황 및 계획, 그 효과를 살펴보고 비전을 제시함으로서 향후 추진해야할 개선방안을 제안하였다.

지능형 교통시스템(ITS: Intelligent Transport Systems)의 부체계인 첨단화물운송시스템(CVOs: Commercial Vehicle Operations)은 교통혼잡 완화와 물류비 목적으로 종합물류정보전산망 사업에서도 추진되어 왔다. ITS 기본계획에서 정의한 화물 및 화물차량관리시스템과 위험물 차량관리시스템의 세부서비스는 '97년말 종합물류정보전산망 상세설계와 첨단화물운송시스템 기본설계 과정에서 새롭게 정립, 제시되었다. 본 고에서는 첨단화물운송시스템의 서비스와 소요기술 개발현황을 기존의 지능형 교통시스템과 종합물류정보망의 추진계획, 업계의 관련자료를 바탕으로 비교적 상세하게 검토하고, 현재까지 공공과 민간에서 개발, 적용되고 있는 시범서비스 차원의 첨단화물운송시스템의 소요기술 적용사례와 효과를 분석하고자 하였다. 본 고에서 첨단화물운송시스템의 적용사례로서 해양수산부를 중심으로 현재 구축 운영중인 컨테이너터미널 전자문서교환(EDI: Electronic Data Interchange) 및 GATE 자동화시스템과 '97년 7월부터 본격 가동에 들어간 현대물류 택배종합전산시스템(HYDEX)의 정보서비스와 관련한 요소기술과 함께 그 효과를 살펴보고, '96년 12월부터 시범서비스를 제공중인 한국통신의 화물운송정보시스템의 적용효과를 분석하였다.
