During practices of traffic management, the performance achieved was determined by traffic practitioners' ability of decision and knowledge as well as traffic equipments assisting the practitioners. Therefore, sometimes self-evaluations done by the traffic practitioners in a specific traffic organization can be used to indirectly evaluate the traffic management organization. The present paper is to evaluate a specific highway agency using self-evaluations performed among different highway agencies including one Japanese highway agency. The result indicated that the agency is superior to other agencies in characteristics such as performance, activity, preparation for the future, and customer orientation. For more detailed-branch based study, the responders were divided into their belonged branches like headquarter, regional headquarter, maintenance office and research center. The results provided that various deficiencies of traffic management were found and could be improved in the future.

Since Intelligent Transport Systems(ITS) is a complex project combining technology and system of transportation, information and communication and civil engineer, it needs a specialized management activities. However, it is difficult to judge who has responsibility for a shoddy and fault construction since the role between project management and supervision is very ambiguous. The aim of this study is propose an efficient project management and supervision for ITS reflecting the characteristics of ITS. Therefore, we suggest a statistical models using nonlinear regression model to prepare the project management and supervision compensation criteria, hence, we choose the realistic and validation statistical model.

In this paper, we propose the system structure and technologies to implement a business model for an intelligent traffic facility management system based on ubiquitous technology. The business model includes the service functions, service structure, business process, and demand and supply relationship among the participants in this model. We also propose an approach to implementing the model. This includes the network, infrastructure and platform to be used for system composition. We then present the results from an analysis by comparison of different technologies and an adequate technology structure. Finally, this paper may present guidelines to managing traffic facilities.

A dedicated short-range communications (DSRC) traffic information system is a detection system for a section of road using communication between roadside equipment and on-board High-Pass units to collect road traffic information and provide reliable traffic information to drivers. The Ministry of Land, Infrastructure, and Transport announced that a DSRC system must be supported to pass the performance evaluation of an intelligent transportation system (ITS), and the performance evaluation for DSRC systems installed in expressways and national highways is started. Currently, DSRC traffic information systems are only managed for maintenance and functional-monitoring purposes, which means that detailed criteria for the operation of a DSRC traffic information system, such as communication range, the direction of the antenna, and the power of the radio wave, etc., need to be established. In this paper, the criteria of the performance evaluation of a DSRC traffic information system are presented for different road types and road environments. The proposed performance evaluation criteria included the communication range and communication power of roadside equipment. In addition, installation criteria, such as the direction of the antenna, and the height and angle of the installed system, are presented for different road types and road environments. The criteria presented were evaluated for DSRC roadside equipment and documented to improve system maintenance and quality control of the communication system.

현재 한국도로공사에서 운영하는 고속도로 교통관리시스템(FTMS)과 우회도로 교통정보시스템(ARTIS)은 차량 검지 장치와 CCTV 를 통해 실시간 교통 자료를 수집하고, 도로전광표지(VMS), 방송, 인터넷 등 다양한 매체로 교통 정보를 제공하는 시스템이다. 이러한 시스템들은 매일 도로에서 수집되는 엄청난 양의 교통 자료를 실시간 교통 정보 제공하는데 목적을 두고 있어, 교통 자료를 가공하고 처리하여 분석을 수행하는 연구 환경을 제공하는데 어려움이 많다. 본 논문에서는 여러 시스템으로부터 대용량의 교통 자료를 가져와 하나의 통합 데이터베이스로 구축하고, 이를 통해 얻은 교통 이력 자료를 연구할 수 있는 환경을 제안한다.

The TAGO and TOPIS systems have limitations in providing not only information collection problems but also customized information that meets the requirements of users in providing information. In addition, there is a lack of integrated link information for various means. In addition, there is a limitation in using public transportation because all the users can not conveniently use public transportation because of lack of user - customized information and traffic - related information. In this paper, in this paper, we analyze the current status of domestic and international public transport information systems and services, Through this, we expect to be able to provide customized information tailored to the requirements of users by providing integrated linking information for various means.

텔레매틱스 서비스를 위해서는 우선 가장 기본이 되는 교통정보의 제공체계가 뒷받침되어야 하는데, 현재 우리나라의 교통정보 수집 및 제공 체계는 이를 담당하는 각 지자체 및 업체들에 따라 별도의 시스템들을 구축하고 있어 종합적이며 체계화된 정보서비스를 필요로 하는 텔레매틱스 상용화에 문제점으로 지적되고 있다. 이를 해결하기 위해 범국가적 차원에서 교통정보의 수집 및 활용, 통합운영ㆍ관리방안을 마련하여 종합교통정보서비스 사업을 활성화할 수 있는 체계화 방안을 제시할 필요가 있으며, 이는 텔레매틱스를 위한 통신 인프라의 국제적인 기술 방향에 따른 국가 도로체계 정보화 인프라 구축방안을 전략적으로 제시하기 위한 필수적인 요소라 할 수 있다.(중략)

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 aims to change and expand present traffic regulation from the human driver to Automated Vehicle(AV), we conducted an in-depth interview(IDI) into the traffic regulation service's strategy for an AV-related information consumer group(AVs and service developers) and a manager group (an information service management agency). The IDI results confirmed several important opinions and requirements for an information service by regulatory information manager groups (enough for AV development), such as a systematic need for dynamic regulatory information and a unified information management system. Also, we find out implications about adopting the Internet of Things (IoT) technology in traffic safety facilities to provide dynamic regulation information on the roads.

This research proposes strategies about providing detour route information and traffic management for flood disasters. Suggested strategies are based on prevention and preparation concepts including prediction, optimization, and simulation in order to minimize damage. Specifically, this study shows the possibility that average travel speed is increased by proper signal progression during downpours or heavy snowfalls. In addition, in order to protect the drivers and vehicles from dangerous situations, this study proposes a route guidance strategy based on variational inequalities such as flooding. However, other roads can have traffic congestion by the suggested strategies. Thus, this study also shows the possibility to solve traffic congestion of other roads in networks with emergency signal modes.
