The main factors that made Seoul's rapid population accommodation and urbanization possible in the mid-to-late 20th century were the ex-pansion of urban infrastructure, completion of the transportation system, and housing supply. The development of transportation and resi-dential development occurred simultaneously, and in particular, apartment complexes, a representative residential area in Seoul, were most influenced by Perry's neighborhood unit theory. The purpose of this study is to analyze the process of the physical environment of apartment complexes in the metropolitan area in response to development of transportation in the mid-to-late 20th century. The analysis sites are Jamsil Apartment Complex(1974), Dunchon Apartment Complex(1979), Mok-dong New Town(1983), Sanggye New Town(1985), Bundang New-town(1990) and Ilsan Newtown(1990), which were planned at the turning point of development of transportation and actively reflect the neigh-borhood unit theory. The analysis was conducted in three stages. Analyzing the status of transportation when the plan was established, deriv-ing the planning elements, and classifying the planning elements into walking, bus, car, and subway which is the representative transportation. The conclusions from the analysis are as follows. Firstly, completing the legal system and expanding the related infrastructure are essential. Secondly, in contrast to the increase in traffic volume, the pedestrian environment has been continuously improved. Thirdly, despite the emergence of new mode of transportation, there was a tendency to activate the linkage between transportation.

The concept of smart city is understood as an indispensable component of urban regeneration projects in small cities in terms of providing a better urban environment and efficient living systems with a limited budget. Recently, the Korean government revised the law that related to the construction of the smart city and started to implement the smart city concept not only to new-large urban development but also to small-existed regeneration projects. However, it is difficult for small and medium-sized cities that are suffering from the insufficient professional workforce; knowledge supports for high-tech and lack of professional networks to proceed smart city planning and project that containing regional characteristics. This paper aims to examine the effective way of urban regeneration for small and medium-sized cities through smart city planning and strategy. As an important case, this paper looks at the 'Smart City Challenge' competition that was hosted by the US Department of Transportation in 2015. It examines the background and operation process of the smart city challenge competition, and then analyses each city's strategy and characteristics of seven finalists. This paper highlights the several key lessons to Korean cities: 1) the importance of national government's support in financial and professional resources; 2) the cooperation with local governments and IT corporations which provides realistic and detailed technical solutions; 3) the holistic and integrated approach to urban regeneration starting from transportation issues; 4) the necessity of the government's clear visions and guidelines toward the smart city.

본 연구는 최근 정부의 주요 에너지 관련 정책 중 하나인 지능형 전력망 확산 사업 중 대규모 장비와 전기차, 충전사업 등 다양한 이해관계자가 얽혀있는 지능형 운송 서비스를 도입하는 데 대한 객관적 타당성을 검증하기 위한 방안을 제시하였다. 지능형 운송 서비스를 구성하기 위한 기본적인 사업 모형을 설계하고, 해당 사업에 참여하는 이해관계자를 정의하였으며, 전기차 이용에 따른 이해관계자간 상호 거래를 중심으로 경제성 분석을 위한 기준을 제시 하였다. 특히, 전기차 이용자와 충전사업자의 경우 전기차 보급 규모에 따른 경제성이 크게 달라지는 만큼 극단적인 두 보급 시나리오를 설계하여 각 이해관계자들이 수익 구조가 어떻게 달라지는 지를 비교 분석하였다. 분석 결과 초기 장비 투자비용에 대한 부담을 가진 전기차 이용자와 충전사업자의 경우 해당 사업에 참여하기 위한 경제적 타당성을 확보하기 어려운 상황인 반면 전기차 및 충전설비 공급자의 경우 일정 수준 이상의 수익을 보장받을 수 있을 것으로 예상되었다. 특히, 해당 사업의 추진과 지원의 책임을 가진 정부의 경우 전기차 보급에 따른 에너지 수입 비용 및 이산화탄소 배출 절감에 따른 편익 증가를 통해 전기차 보급 규모에 따라 타 이해관계자에 비해 높은 수익을 보장받을 수 있다는 점을 발견하였다. 따라서 전기차 이용자와 충전사업자에 대한 지원 비율을 일정수준 높일 필요가 있으며, 전기차 사용자와 충전사업자 간 이해가 상충되는 전기차대 충전설비 비율에 대한 다양한 시나리오 분석이 추후 수해되어야 할 것이다. 본 연구의 결과를 통해 향후 성공적인 지능형 운송 서비스 확산을 위해 필요한 사항을 개별 이해관계자 관점에서 확인하는 데 활용될 수 있을 것이다.

Recently, the popularization of personal mobility(PM) has made it possible to see many electric scooters. The energy source of personal transportation used by the general public and the disabled can be seen as environmentally friendly as electricity. Personal transportation means are divided into small electric vehicles because they use electric energy, and they are being treated as new models by automobile manufacturers in each country and spurring development. On the other hand, personal transportation means may cause various types of traffic accidents as they travel between roads and a human walk. In order to prevent such accidents, it is judged that the enactment of laws on the establishment of specifications for electric scooters, which are personal transportation means, and the method of restricting road operation should be given priority. The electric scooter is basically different from the conventional vehicle. The steering shaft of the steering system applied to the electric scooter one to two is possible. 1 to 2 the front-wheel under the steering column is used. It is classified according to the number of wheel installed at the electric scooter is the vehicle body into 2 wheel - electric scooter, and 3 wheel - electric scooter and 4 wheel - electric scooter. In this study, we propose a steering shaft design model that can be applied to an electric scooter, one of personal transportation means. A design model for 1-shaft steering and 2-shafts steering that can be applied to electric scooters is proposed. In addition, we have produced the prototypes for the commercialization of the proposed models, and reviewed the pros and cons of the manufactured prototypes and models.

Currently, urban mobility is rather two-dimensional: Connections between transportation solutions like elevators, escalators, moving walks, and metro stations are static. In the future, urban mobility will require a holistic view: Seamless transportation, enabled by innovative IoT technology, is a necessity. A dialogue between the city, its buildings and transportation systems, considering the specific needs and preferences of each and every citizen, must be adopted. Travelling through the city will become a lot more individualized, interactive and customized to specific requirements.
