  • 본 논문에서는 자율비행(Autonomous Flight)의 연구동향 및 향후 발전방향에 대하여 기술하였다. 자율비행은 항공기의 예기치 않은 임의상황 발생에 대해서도 항공기가 스스로 인지하고, 판단 한 후 대처하는 것을 의미한다. 현재의 자율비행기술은 무인기를 위주로 개발되고 있으나, 차세대 항공교통관제 시스템 도입과 무인기의 활용성 증대 요구에 따라 자율비행기능이 항공교통관제시스템과 결합되어야 한다. 그러므로 현 항공교통관제 시스템의 주요 개요와 향후 변경될 차세대 항공교통관제 시스템의 주요 사항들을 살펴보았고, 자율비행기술 개발 현황을 기술하였으며 향후 발전방향을 전망하였다.

  • Autonomous Station Control System is automatic route control system of large-scale station. The system has flexibility of system step-by-step construction and expandability. A method of step-by-step construction for Autonomous Station Control System has system expansion and subsystem software expansion. The system has autonomous controllability and autonomous coordinability for system step by step construction. With property for a basis, each of subsystem communicates data field. Also, Each subsystem has its own management system, Autonomous Data Manager to manage itself and coordinate with the others. This paper make clear test method for Autonomous Station Control System expansion and software expansion. The first test method of system increasing construction is single station construction test. The second of method is connecting test the neighbor's Autonomous Station Control System. The third of method is connecting test the Autonomous Line Management System. Also, the test method of software expansion take the case of route control subsystem.

  • Purpose: The purpose of this study is to find factors affecting the acceptance intention of autonomous mobility service by applying the unified technology acceptance theory(UTAUT). Methods: The measurement items for each component of this study were modified to meet the purpose of the study by referring to previous studies related to mobility based on UTAUT, which has secured validity and reliability in many studies. The collected data through the online survey were analyzed using hierarchical regression analysis. Results: It was found that performance expectation, effort expectation, social influence, and facilitation conditions for autonomous mobility service had a positive effect on acceptance intention. Also, in this relationship, it was confirmed that driving experience moderated the relationship between performance expectation and acceptance intention, and between effort expectation and acceptance intention. Conclusion: Understanding the public's acceptance of autonomous mobility services, and suggesting strategic implications for the direction of service development to companies that are pushing to enter the autonomous mobility service market.

  • 자율주행차를 신뢰하고 이용하기 위해서는 도로에서의 안전한 주행이 보장되어야 한다. 이를 위해 최우선으로 갖추어야 할 자율주행 인프라는 교통안전시설이다. 한편 도로에서는 Level 3 수준의 자율주행차와 일반 자동차가 혼재하여 주행하고 있기 때문에 기존에 존재하고 있는 일반 교통안전시설의 관리도 추가로 필요하다. 따라서 본 연구에서는 자율주행 인프라 기반 교통안전시설 현장관리 체계를 연구하고, 이를 기반으로 실증지역(판교)를 선정하여(판교) 현장관리 시험시스템을 구현하였다. 시험시스템 구성은 GNSS(Global Navigation Satellite System) 수신기, 현장관리 단말기, 현장관리 App(Application) 등으로 구성하였으며, 현장 실증 결과 도심지에서도 손쉽게 교통안전시설 정보를 송수신하였고, 교통안전시설에 대하여 효율적으로 운영관리 할 수 있음을 확인하였다. 금번 연구결과는 향후 자율주행 인프라의 지자체 확산 및 인프라 구축에 참고자료로 활용될 것으로 기대한다.

  • Research regarding the Autonomous Distributed & Cooperated System has not yet been defined because we need to apply the interdisciplinary approach before so. In this paper, we use a clear definition, compare characteristics of the Autonomous Distributed & Cooperated System and examine the possibility of an actualization through path planning of Autonomous AGV. We propose a new algorithm about the generation method of a moving path at the first stage and a cooperative action generation for a collision avoidance. Lastly, we performed simulation analysis of these two in order to confirm efficiency.

  • This study conducted comparative study on autonomous car's industry policy and corporate strategy of US, China, Germany, Japan and Korea. By analyzing core technologies and industry paradigm shifts of autonomous car industry, I was able to figure out autonomous car has high potential to be dominant transportation in the future and it is important to construct core competency in technology area. The meaningful findings by analyzing various primary and secondary data are as followings: First, in case of US, Google was leading autonomous car industry by developing its own OS and Platform. US government has been actively supporting and interacting with private firms and Universities for stimulating industry/technology convergence and establishing standard. Second, in case of Germany, autonomous car development was leading by several auto makers such as Mercedes, BMW in Hardware and manufacturing area, and German government was focusing on deregulations for private company. Third, in case of Japan which quite similar with German situation, they were both independently developing technology and expanding alliances with MNCs. And Japanese government was supporting triple helix system construction between local companies and universities. Fourth, in case of China, autonomous car industry was leading by IT companies, and various cooperations between IT companies and automakers were established. Chinese government was regulating foreign companies and supporting domestic companies both in market and technologies Last, in Korean case, the active and extensive alliances were lacking in Korean companies while strategic and strong government supports were missing in public sector. For competing with other countries and players, more active collaboration between different countries and strong policy supports are needed in Korean auto industry.

  • 자율주행자동차 활성화를 위한 법·제도 연구는 많았지만, 전략적 관점에서의 자율주행자동차의 활성화 방안에 대한 연구는 미흡하였다. 본 연구에서는 자율주행자동차의 이슈 및 해결방안에 대해 살펴보고, 이를 기반으로 전략적 관점에서의 활성화 방안에 대해 제안하고자 한다. 자율주행자동차의 이슈 및 문제 해결을 위해 안전성 강화를 기반으로 법·제도 표준에 대한 명확한 정립이 필요하며, 교통사고시 책임의 소재와 배상책임의 확보가 선행 되어야 한다. 전략적 관점에서 자율주행자동차의 활성화를 위해서는 자율주행단계에 따른 확산전략을 수립하고, 정부지원정책을 초기 활성화의 트리거로 활용하고, 세그멘테이션(segmentation), 타켓팅(targeting), 포지셔닝(positioning) 전략을 기초로 효과적인 마케팅믹스(4P Mix)전략이 실행되어야 한다.

  • Purpose: Autonomous driving cars, which are often represent the new convergence product, have been researched since the early years of 1900 but their safety assurance policies are yet to be implemented for real world practices. The primary purpose of this paper is to propose a modular concept based on which a safety assurance system can be designed and implemented for operating autonomous driving cars. Methods: We combine a set of key attributes of CE mark (European Assurance standard), E-Mark (Automobile safety assurance system), and A-SPICE (Automobile software assurance standard) into a modular approach. Results: Autonomous vehicles are emphasizing software safety, but there is no integrated safety certification standard for products and software. As such, there is complexity in the product and software safety certification process during the development phase. Using the concept of module, we were able to come up with an integrated safety certification system of product and software for practical uses in the future. Conclusion: Through the modular concept, both international and domestic standards policy stakeholders are expected to consider a new structure that can help the autonomous driving industries expedite their commercialization for the technology advanced market in the era of Industry 4.0.
