Trip reduction policies are increasingly utilized in U.S. metropolitan areas to address congestion and air quality problems. These policies typically focus on the journey to work and are aimed at reducing the amount of drive-alone commuting by providing transit and ridesharing incentives. Severe air quality problems in Southern California have prompted the air pollution control agency for the Los Angeles metropolitan area to enact Regulation XV. The regulation requires employers to develop and implement a trip reduction program to achieve specified ridesharing goals. It is the most ambitious and far reaching such program implemented to date, and offers a unique opportunity to determine whether such programs can significantly affect travel behavior. This paper presents results from the first year of Regulation XV’s implementation.

With the collapse of communism in late 1990's, capitalistic economy has triggered a unprecedented economic boom across the world. On the other hand, some negative side effects, such as disparity in wealth, overproduction and overconsumption, had been exposed simultaneously. A series of historic events brought a new economic perspective to the world, called 'sharing economy', with carsharing standing at the forefront of this trend. In this research, it has been analyzed through BC analsysis if car sharing can compete against BRT as a useful transfer mode serving KTX Osong station, and the result finds that it is competitive enough to replace the BRT. In conclusion, it is strongly recommended that a study of establishing economic feasibility criteria for car sharing is required.

Cheonggyecheon is an ancient stream flowing the downtown in Seoul which was covered by roads and elevated highway in the city’s economic development period. Seoul metropolitan government decided to revitalize this dried stream under the covering and its desolated district into a linear park and to provide to the citizens an urban amenity in 2002. The project completed in 2005 has had series of positive impacts, especially to activate walking and commerce in the area. Unlike elevated highway removals such as Big Dig project, this study reveals that Cheonggyecheon restoration has given land price premiums to the area with urban characteristics associated with clearness of the stream. These variables have altered their strengths on the property value according to the city’s business fluctuation. The global economic crisis in 2008 lessened the impact of urban amenity on the land price near Cheonggyecheon, while increasing that of the infrastructures such as bus accessibility.

한국형 자율주행차 윤리가이드라인 구성과 쟁점에 대한 분석

변순용 ( Byun¸ Sunyong ),황기연 ( Hwang¸ Keeyeon ) 한국윤리학회 2021 倫理硏究 Vol.134 No.1

자율주행자동차(Automated Vehicle, 이하 AV)의 기술이 발전하고 기초적인 수준의 AV가 판매되면서 AV의 보급과 이용에 관한 관심이 나타났다. 실제로 AV가 도로에서 운행되면서 발생하는 사고와 앞으로 더 높은 수준의 AV가 운행되며 날 수 있는 사고는 AV의 기존의 인간이 운전하는 자동차 사고와 다른 윤리적 문제를 야기할 것이다. 이에 AV의 생산자와 탑승자, 비탑승자간에 동의가 이루어 질 수 있는 윤리적 가이드라인의 검토가 필요하다. AV 윤리가이드라인을 구성할 때 생산자, 탑승자, 비탑승자의 주체들과 책임문제를 고려하지 않는다면 더 높은 수준의 AV의 운영 자체가 힘들어질 수 있기 때문에 AV 윤리가이드라인에서는 여러 가지 윤리적 쟁점을 고려하고 우리나라의 상황과 문화에 맞는 윤리적 기준을 제시해야 사회적 합의가 가능할 것이다. 대표적으로 불가피한 위법과 사고, 일반적으로 쉽게 받아들여지는 공리주의적 접근의 장점과 한계, 윤리적 책임의 문제, AV의 윤리적 판단 범위, 투명성과 개인정보의 보호의 문제, 운행판단 기준의 설정 주체 문제를 중심으로 AV 윤리가이드라인의 쟁점을 분석하였다. 앞으로 기술의 발전과 함께 국내에서 운행될 더 수준 높은 AV의 윤리적 가이드라인을 앞서 말한 쟁점을 중심으로 하여 수정방안을 제시하고자 한다. As the technology of Automated Vehicle(hereinafter referred to as AV) has developed and the basic level of AV has been sold, interest in the spread and use of AV has emerged. Accidents that occur while AV is operated on the road and accidents that may occur as AVs are operated at a higher level in the future will cause ethical issues different from those of conventional human-driving car accidents of AV. Therefore, it is necessary to review the ethical guidelines that can be agreed between AV producers, passengers, and non-passengers. When composing the AV ethics guidelines, if the producers, passengers, and non-passengers and responsibility issues are not taken into account, the operation of higher-level AV itself may become difficult. A social consensus will be possible only when ethical standards suitable for the situation and culture of our country are presented. Representatively, it focuses on unavoidable violations and accidents, the advantages and limitations of the generally accepted utilitarian approach, the issue of ethical responsibility, the scope of AV's ethical judgment, the issue of transparency and protection of personal information, and the issue of the subject of setting the operating judgment standard. with the AV ethics guideline. In the future, along with the development of technology, I would like to propose a revision plan focusing on the aforementioned issues regarding the ethical guidelines for higher-level AVs that will be operated in Korea.

클러스터링을 통한 역세권 잠재 개발역량 평가 연구 : 서울시 2호선 대중교통 용량 및 토지 특성을 중심으로

As the problems caused by rapid urbanization and reckless urban development were raised, Transit Oriented Development (TOD), an eco-friendly and sustainable complex development centered on public transportation, is being developed in urban railway station areas in metropolitan Korea. Hence, it is deemed necessary to evaluate the development potential for areas where urban development is required and find ways to efficiently utilize the urban space. However, although the Seoul Government’s urban master plan classified the spatial structure according to the central system for balanced regional development, due to the large size of the area, there is a limit on the development area suitable for the characteristics of a small area such as a single station. This study aims to evaluate the development potential of the station area of Seoul Metro Line 2 based on the current maximum capacity of public transportation and land characteristics. Furthermore, it aims to devise a method for the efficient utilization of urban space by reorganizing the existing central system. Through the analysis, we found station areas that required further development and confirmed the need for the expansion of the central system and addition of a hub. Specifically, in the case of Dongbuk (Northeastern region), there were a total of four metro lines in Wangsimni and significant traffic demand. However, compared to four other regions, overall development indicators were low. Thus, it is necessary to have additional development based on Konkuk University and Seongsu, which have sufficient transportation capacity. This study is expected to contribute to balanced regional development by evaluating the development potential of TODs based on the current development capacity of the station area Metro Line 2 and propose a reorganization of the central system of the “2030 Seoul Plan,” the urban master plan of Seoul.
