The purpose of this study is to analyze factors that affect road users' acceptance of fully autonomous vehicles (level 4 or higher). A survey was done with drivers of general cars and pedestrians who share roads with fully autonomous vehicles. Five acceptability factors were selected: trust towards technology, compatibility, policy, perceived safety, and perceived usefulness. The effect on behavioral intention was analyzed using structural equation modeling (SEM). The perceived safety and trust towards technology were found to be very important in the acceptance of fully autonomous vehicles, regardless of the respondent, and policy was not influential. Compatibility and perceived usefulness were particularly influential factors for drivers. In order to improve the acceptance by road users, securing technical completeness of fully autonomous vehicles is important. Certification and evaluation of the safe driving ability of fully autonomous vehicles should be thoroughly performed, and based on the results, it is necessary to improve the perception by road users. It is necessary to positively recognize fully autonomous vehicles through education and publicity for road users and to support their smooth interaction.

The fully autonomous vehicle, which has been actively studied in a worldwide before commercialization, is expected to become a living space by securing time and space compared to existing automobile. For this reason, interior design of fully autonomous vehicle has become very important. To enhance passenger's experience and satisfaction in fully autonomous vehicle, it is necessary to design an optimized space that can support in-vehicle activities. For this purpose, efforts to analyze the passenger's in-vehicle activities should be preceded. However, there were limited studies that define space and in-Vehicle activities of fully autonomous vehicle in Korea. The purpose of this study is to suggest the guideline of the interior design of fully autonomous vehicle by analyzing and classifying the scope of activities that the passenger can perform within the vehicle. As a method of the study, literature studies on future concept cars, human lifetime behavior and consumer needs had been conducted. As a result in-vehicle activities could be applied in a fully autonomous vehicle. Four in-vehicle activities 'work', 'home life and personal care', 'relaxation' and 'conversation and hobby' had been derived through the analysis of in-vehicle activities. Based on the results, the interior design of fully autonomous vehicle guideline has been suggested. The study is significant because the result of the study can act as a basic study which considers the activities in the fully autonomous vehicle environment.

The era of fully autonomous vehicles which can travel to their destination completely, is expected to arrive in the near future. The automobile industry will face a huge change in the near future. It makes the industry in the midst of a major turning point, since the automobile was born in the late 1800s. It is expected that the fully autonomous vehicle will be defined as a part of a living space beyond the concept of transportation. However, the existing research on the interior design of the fully autonomous vehicle is insufficient. The purpose of this study is to propose a design method of interior space through analyzing in-vehicle activities, which is a fundamental design element that can satisfy user's emotional experience suitable the concept of living space. For this purpose, the consumer's consciousness about the in-vehicle activity of fully autonomous vehicle was investigated. As a result, domestic consumers perceived the needs of in-vehicle activities related to resting, listening and watching activities such as 'sleeping and resting', 'watching TV and movie', 'listening to music' among 'self - centered' activities. Based on the results of the investigation, this study will suggest a design method of interior design of the fully autonomous vehicle. This study is meaningful, because it is a leading research that suggests new ways of designing interior space by analyzing consumer's needs in a quantitative method.

Due to the recent changes in residential value, user needs for various spaces in residential space are increasing. However, it is not easy to change and reconstruct the first residential form according to the needs of the user due to the characteristics of the residential space where movement and deformation are difficult. Therefore, this study aims to derive a plan to meet user needs according to changing residential value by using fully autonomous vehicles with a concept of space that can be moved. First, the existing residential space was classified through literature research, and based on this, the space type of the fully autonomous vehicle for the residential was derived through user research. Then, through the survey method and statistical analysis, user needs analysis for residential space, usefulness analysis of derived space type and type specification were carried out. Finally, based on the results of the study, the design direction of the fully autonomous vehicle for residential purpose was presented. Based on the user's perception, it is meaningful that it categorizes the space of the fully autonomous vehicle for residential purposes and suggests the design direction.

운전자가 필요없는 완전한 자율주행 시대에 있어, 자율주행 차량에 탑승한 사람의 상황인지 측면에서 불안감을 예측하고 이를 저감하는 방법은 매우 중요하다. 본 논문에서는 탑승자의 불안감을 유발시키는 자율주행 환경 요인으로 도로 환경, 차량의 내·외부 환경, 자율주행 제어 환경의 3가지 요소가 도출되었고, 각 요소에서 탑승자의 불안감을 유발시키는 세부 요인들을 도출하여 분석하였다.

인공지능(AI)과 연산능력의 발전에 따라 자율주행은 가까운 미래에 완전한 모습으로 우리들 앞에 나타날 것이다. 자율주행 시대의 자동차는 단순한 이동 수단이 아니라, 이동하는 개인 집과 같이 휴식과 여가 생활을 즐길 수 있는 공간이다. 다시 말해서 자율주행으로 말미암아 차량에서 늘어난 여가생활은 미디어 시청으로 이어지고, 이는 기존의 스마트 폰이 아닌 AR(Agument Reality)기술과 파노라마 스크린 기술 성장과 동반하여 개인 공간 천체를 이용한 몰입된 미디어 시청이 될 것이다. 본 문서는 자율주행 시대에 걸맞는 새로운 미디어 시청에 필요한 환경분석과 기술적 요구사항을 언급하고자 한다.

The introduction of autonomous vehicles will bring about not only changes in existing automotive ecosystem but also widespread changes in our lives, society, economy, and culture. Social acceptance is one of important influencing factors for the commercialization of autonomous vehicles. The purpose of this study analyzes influencing factors in the acceptance of autonomous vehicles in terms of consumers. Autonomous vehicles in this study were defined as PAV (Partial Autonomous Vehicles) and FAV (Full Autonomous Vehicles) by drivers' intervention or not. The survey was conducted over 20 years old including not only drivers but also non-drivers. The results showed that the factors affecting acceptance of PAV and FAV were different. Factors directly related to drivers influenced PAV acceptance while external environmental factors influenced FAV acceptance. This study is proved that is should need different strategies between PAV and FAV for increasing those acceptance

주행 중인 자율주행차의 탑승자는 차량의 거동을 예측할 수 없기 때문에 불안함을 느낄 수 있으므로 차량의 거동 정보를 사전에 탑승자에게 전달하여 심리적 안정을 제공하는 것은 중요하다. 본 논문에서는 완전 자율주행 상황을 가정하여 자율주행 시스템이 발생시키는 주행 의도를 탑승자에게 전달하는 하드웨어 시스템을 제안한다. 제안하는 시스템은 자율주행차량이 사전에 생성된 경로를 따라 주행하면서 출발, 정지, 방향 전환 등과 같은 총 5 가지 상황에 대한 시각, 청각 및 촉각 알림을 통한 자율주행 의도 전달하는 것을 고려한다. 차량용 시트에 모터를 부착하여 촉각 알림을 통해 자율주행 의도를 전달 하였으며, 모니터를 통해 시각 및 청각 알림을 통해 자율주행 의도를 전달하였다. PC 에서 개발에 필요한 시뮬레이션 데이터를 처리하였으며, 시뮬레이션 환경에서 개발, 실험 및 평가가 진행되었다.

In level 5 (mind-off) of autonomous driving, the autonomous vehicle passengers are expected to have various activities such as face-to-face meetings, working, relaxing, and watching movies. In particular, various changes in the interior space of the vehicle are expected. Moreover, according to the survey conducted by the American Automobile Association, 73% of the respondents reported that they were afraid to board autonomous vehicles. In level 5 of autonomous driving, the subject of safety was expected to be transferred to autonomous vehicles; thus, research should be conducted from the user's perspective. Recently, various studies have been conducted to secure the safety of fully autonomous vehicles. However, there are limited studies addressing the psychological safety of actual passengers. Therefore, this study conducted a questionnaire based on the AHP technique. Consequently, the automobile safety system's priority for securing passengers' psychological safety according to each type of indoor behavior was derived, and the interior space for securing the psychological stability of passengers was suggested based on the obtained results. This study offers a new direction for interior space design, satisfying the psychological safety of passengers. This study is important because it advocates that the interior environment of fully autonomous driving cars is expected to be designed to secure the user's psychological safety.
