MRTS System in Delhi: Increase in Mode Choice and its Mobility and Equity Implications

Kirti Bhandari,Hirokazu Kato,Yoshitsugu Hayashi 서울시립대학교 도시과학연구원 2008 도시과학국제저널 Vol.12 No.2

The concern for policy makers is to find suitable answers for the growing mobility needs in most developing cities, as they are currently facing serious problems related to increasing road traffic leading to traffic congestion and pollution. Since most transportation is a derived demand, the goal of transport policy should be to improve mobility so as to enhance accessibility. This paper begins by identifying the mobility needs associated with access to different urban facilities in a rapidly developing mega-city, Delhi. Mobility preferences by population groups, income classes, location, vehicle ownership and by mode are presented. Second, the paper tries to examine the mobility benefits due to the introduction of the MRTS system in Delhi. The standard multinomial logit formulation is used to estimate mode-destination choice model for two scenarios; before and after an introduction of the MRTS for work trips. The change in value of time, representing the change in wage rate, is used as a measure of mobility. Finally, the study proposes a link between mobility and equity using the well established quantitative measure of equity, the Gini coefficient. Results indicate that the introduction of the MRTS system leads to the change in the value of time by Rs/hr 33.74 (0.69 $US/hr). Further, the equity implications of the increase in value of time suggest a positive change (towards equity).

대학캠퍼스 내에서의 퍼스널 모빌리티 이용에 대한 사용자 인식 조사

양인범 한국산학기술학회 2022 한국산학기술학회논문지 Vol.23 No.6

Personal mobility provides first-mile and last-mile mobilities and plays an important role in the daily short-distance movement of individuals. However, despite high expectations for the social functions and alternative roles of personal mobility, the growth of personal mobility has been limited due to several factors, such as the lack of social consensus and the infrastructure needed for personal mobility. Therefore, it is important to explore a plan to promote the dissemination of personal mobility for the future cities, and a study on the activation plan for personal mobility in a specific area, such as a university campus, is required first. So, a survey responded by college students was conducted to investigate user awareness of personal mobility. The survey results on the general user awareness of personal mobility and the user awareness of the use within the university were analyzed, and a cross-analysis was performed. Notably, the understanding of personal mobility was generally low, but the demand for the introduction and activation of personal mobility within the university was high among the respondents. In addition, the preference for the means of transportation under personal mobility was high for manpower mobility and electric scooter, while the preference for an electric bicycle was relatively low. In addition, the cross-analysis showed that user experience affected the detailed response patterns. In effect, this study is expected to be used in various related research fields, such as proposing ways to activate personal mobility, reforming legal systems to incorporate personal mobility into them, and urban personal mobility design. 퍼스널 모빌리티는 퍼스트 마일과 라스트 마일 개념의 이동성을 제공하며 동시에 개인의 일상 단거리 이동에서 중요한 역할을 한다. 이러한 사회경제적 기능과 대안 역할에 대한 높은 기대에도 불구하고, 법제도 등 사회적 합의와 지원 인프라 부족 등 여러 요인으로 인하여 제한적인 성장에 머물고 있다. 따라서, 미래 메가시티를 위한 퍼스널 모빌리티의 보급 활성화 방안을 탐색하는 것은 중요한 의미가 있으며 특히, 대학캠퍼스와 같은 특정 구역에서의 활성화 방안 연구가 우선 필요하다. 이러한 탐색의 선행 연구로써 전국 대학생을 표본으로 설문조사를 실시하여 퍼스널 모빌리티에 대한 사용자 인식 조사를 수행하였다. 퍼스널 모빌리티에 대한 일반적인 인식 조사와 대학캠퍼스 내에서의 이용에 대한 인식 조사 결과를 분석하고 항목 간 교차 분석을 수행하였다. 응답자들의 퍼스널 모빌리티에 대한 이해도는 전반적으로 낮았으나, 대학캠퍼스 내에서의 퍼스널 모빌리티 도입 및 활성화 요구는 높은 것으로 나타났다. 이동 수단에 대한 선호는 인력 이동과 전동킥보드가 높았고, 전기자전거에 대한 선호도는 낮았다. 항목 간 교차 분석을 통하여 사용자 경험이 세부 응답 패턴에 영향을 미치는 것을 알 수 있었다. 이러한 인식 조사 결과는 향후 퍼스널 모빌리티 활성화 방안 제시, 법제도 정비 및 도시형 퍼스널 모빌리티 디자인 연구 등 다양한 영역에서 활용될 것으로 기대된다.

Localized Mobility

Schafer, P.,Brubacher, C.,Hwang, M.J 한국공공사회학회 2018 공공사회연구 Vol.8 No.1

주요 대도시의 미세먼지의 원인이되는 자동차의 매연과 날로 증가하는 도심지 교통체증의 문제로 인하여, 자동차의 사적 소유에 대한 의문이 제기되고 있다. 이러한 상황에서 이동에 대한 패러다임의 전환적인 사고가 요구되고 있다. 이는 보다 현대적이고 다양하며 환경친화적이고 지속 가능한 유형의 공유적 이동의 시대가 도래하고 있음을 의미하는 것이다. 이러한 전환점에서 본 연구자들이 선행연구에서 제언한 “이동의 지역화를 기반으로 지역성과 지역사회의 수준에서 이동행위에 대한 이론적으로 구성된 개념체계로 설명하였다. 지역적 수준이란 시민이 높은 빈도로 혹은 활발하게 생활하고 이동하는 수준이나 단위를 의미한다. 이 수준에서는 이동이 구성되는 형태에 가장 큰 영향력을 가지고 있음을 의미한다. 본 연구에서는 “이동의 지역화” 연구의 이론적 구성을 넘어서, 구체적인 사례로서의 지역적 맥락을 가지고 이 이론이 어떻게 구성되고 또 얼마나 확장성을 갖고 적용될 수 있는지에 관한 이론적인 평가와 함께 논의를 전개할 계획이다. 준거적인 분석틀로서 세종시를 대상으로 실시한 사례연구방법론이 적용되었다. 한국의 세종특별자치시는 독특한 원형의 이동 네트워크를 가지고 있는 계획도시로서 환승-지향적인 개발과 도시 전체에 대한 공정한 접근을 강조한 특성을 가지고 있다. 본 연구를 통해서 지역사회가 경험하고 있는 고유의 이동문제를 해결하기 위한 수준높은 인식론적인 기반 위에 원칙적인 적용과 실천에 있어서 맥락적으로 섬세한 수준의 지역화된 이동에 대한 이해를 얻기 바란다. By virtue of disillusionment with private car ownership becoming incrementally more apparent, and as a result of increasing fine dust levels and traffic congestion proliferating in major world cities, a mobility paradigm shift is underway. Preferred travel modes are evolving with greater momentum towards contemporary, multi-modal, and environmentally sustainable forms of shared mobility. This shift is mentioned in recent research on ‘localized mobility’, a theoretically established construct pertaining to mobility behavior at the level of localities and communities. The local level is the level at which citizens live and move within most frequently, and thus the level possessing the greatest influence over how their constructions of mobility are shaped. In this paper, the theoretical construct of localized mobility is taken a step further, evaluating a conceptual scheme for how, and the extent to which, it can be practically applied to, and devised to be compatible with, a particular local context. The analytical frame of reference used in this case study is that of Sejong City, South Korea, a planned city designed and built to have a unique ring-shaped mobility network with an emphasis on transit-oriented development and the provision of equitable access to the entirety of the city. Through this study, it is hoped that local communities experiencing their own nuanced mobility challenges can gain valuable cognizance of how to approach the adaptation and implementation of their own context-sensitive version of localized mobility.

권영민,김형주,임경일,김재환,손웅비 한국ITS학회 2020 한국ITS학회논문지 Vol.19 No.3

The manufacturing-oriented mobility system is being reorganized around the future mobility system represented by electrification, sharing, and autonomy, driven by the social demand for sustainable development. Changes in future mobility systems are expected to accelerate thanks to advances in IT technology. To this end, this study conducted an expert survey (N=23) to predict the direction of changes in the future mobility system. Through the survey, ‘mobility sharing’ was selected as a key factor in the future mobility system among four future mobility. In addition, ‘safety’ was selected as the most important service factors in future mobility system among eight future mobility service factors. We hope that the results of this study will be used as basic information to design policies and service directions of preparation for the future mobility system. 제조업 중심의 기존 모빌리티 시스템은 지속가능한 발전에 대한 시대적·사회적 요구에 힘입어 전기화·공유화·자율화로 대변되는 미래 모빌리티 시스템을 중심으로 재편되고 있으며, IT 기술 발전에 힘입어 교통수단 혁신의 변화는 가속화될 전망이다. 이에 본 연구는 미래 모빌리티 체계 변화에 대한 방향성을 예측하고자 미래 모빌리티 전문가들(N=23)을 대상으로 설문조사를 실시하였다. 설문조사를 통해 공유모빌리티, 자율주행자동차, 전기자동차, 통합교통서비스 등 4가지 미래 모빌리티 수단 및 서비스에 대한 영향력 및 변화정도를 측정한 후 이를IPA(Importance Performance Analysis) 분석을 통해 확인하였다. 분석결과 공유모빌리티가 미래모빌리티 시스템의 핵심요인으로 선정되었다. 또한, 미래 모빌리티 서비스 제공 방향성 탐색을위해 8가지 서비스 요인(안전성, 친환경성, 심미성, 편의성, 정시성, 접근성, 수요응답성, 개인이동성)에 대한 AHP(Analytic Hierarchical Process) 분석을 실시하였으며, 그 결과 ‘안전성’ 요인이미래 모빌리티 서비스에서 가장 중요한 요인으로 평가되었다. 본 연구의 결과가 미래 모빌리티체계 변화에 대응하는 정책 및 서비스 방향을 설계하기 위한 기초자료로 활용되기를 기대한다.

일본 모빌리티 산업동향 및 토요타자동차 전략

박정규(Jeong-Gyu Park),이형오(Hyung-Oh Lee) 한일경상학회 2023 韓日經商論集 Vol.101 No.-

Purpose: The purpose of this study is to look at trends in the Japanese mobility industry, analyze Toyota Motor’s mobility strategy, and then seek implications for the Korean government and companies. The reason for looking at Japan’s industrial trends is that not only has Japan made various efforts early on in this field, but Korea is similar to Japan in demographic structure, and so there are many things to refer to from Japan’s industrial trends. Also, looking at Toyota Motor’s case in relation to corporate strategy, we can find that the company not only clearly presents its strategy as a mobility company, but is actually implementing it by launching various products and services. Research design, data, and methodology: As to the Japanese mobility industry trend, we first briefly look at the Japanese government’s policies, and then look at the trends by components of the mobility industry such as electric vehicles, autonomous driving, personal mobility, and flying cars. And regarding Toyota Motor’s mobility strategy, we look at electric vehicle strategies and development organizations, and look at strategies for each field, including automobiles, MaaS, personal mobility, and flying cars. Results: As a result of analyzing trends in the Japanese mobility industry, the following points were confirmed. At first, the basic direction of mobility policy in the Ministry of Economy, Trade and Industry was securing mobility services that provide new value, realizing carbon neutrality and reducing traffic accidents, and strengthening the industry’s international competitiveness. In the automobile industry, we find that the electrification of automobiles had a significant impact on the industrial structure, resulting in the weakening of the vertical division of labor and the advancement of the horizontal division of labor. In the mobility field, not only automobiles but also personal mobility plays an important role. The Japanese government was promoting deregulation in this field, and startups were playing a large role in the private sector. In addition, in the field of UAM, or flying cars, the government and the private sector were cooperating to improve various standards. In addition to industry trends, this study examined the strategy of Toyota Motor Corporation, and found that the company is advancing into each field that makes up the mobility industry and pursuing business in all directions. First, in the automobile sector, the company was a little late in moving to electric vehicles, but it set a new direction by announcing a large-scale electric vehicle investment plan in December 2021. In addition to investing in electric vehicles, the company was pursuing a transformation of its automobile business from hardware-centered to MaaS-centered, the key elements of which were MSPF and Autono-MaaS. The company also actively entered the personal mobility field and the UAM or flying car business. Implications: This study presented the following implications for Korea through consideration of the Japanese mobility industry. First, there is a need to actively refer to Japanese policies when establishing mobility-related policies at the Korean government level. Second, Korean companies also need to actively utilize the experience of Japanese companies, especially in the service sector, when establishing mobility strategies. Thirdly, there is a need for companies in the two countries to jointly solve social problems of both countries and to explore the global market through cooperation, and to this end, the government’s efforts to revitalize exchanges between companies from both countries are needed.

여행 모빌리티 및 모빌리티 애플리케이션의 품질이 여행 만족도에 미치는 영향 -대중교통 이용 시 발생하는 스트레스의 조절 효과를 중심으로-

김현지,최정원,구철모,정남호 한국관광학회 2021 관광학연구 Vol.45 No.2

Contemporary tourists strive to relieve the stress of travel mobility and increase travel satisfaction by acquiring mobility information using travel mobility applications(apps). This study aims to understand the effect of a travel destination’s mobility environment on travel satisfaction in various ways by focusing on the effect of stress generated when using travel mobility. Specifically, we explored how quality of travel mobility, quality of travel mobility apps, and stress affect the overall travel satisfaction. In particular, we attempted to verify the moderating effect of stress on travel satisfaction. An online survey was conducted on tourists who have used a travel mobility app in the travel destinations for the past one year, and the Partial Least Square (PLS) method was applied. As a result, it was confirmed that the quality of travel mobility and the travel mobility app's quality positively affect overall travel satisfaction. However, there is a difference in the positive influence depending on the level of stress. As the stress generated when using mobility increased, the influence of travel mobility satisfaction on overall travel satisfaction decreased. Conversely, the influence of travel mobility app satisfaction on overall travel satisfaction increased. It means that the greater the stress tourists receive when using travel mobility, the stronger the travel mobility app’s effect. These results can be valuable as an introductory study in understanding tourists’ stress and how to cope with them. Moreover, it can be used as basic research for verifying the effectiveness of smart technology that can manage the stress that can occur in various spaces of travel destinations. 오늘날 관광객은 여행 모빌리티 애플리케이션(앱)을 활용해 정보를 획득함으로써 여행 모빌리티 이용 시 발생하는 스트레스를 해소하고 여행의 만족도를 높이고자 한다. 이에 이 연구는 여행 모빌리티 이용 시 발생하는 스트레스의 영향에 초점을 맞추어 여행지의 모빌리티 환경이 여행 만족도에 미치는 영향을 다각적으로 이해하고자 한다. 구체적으로 여행 모빌리티 품질, 여행 모빌리티 앱 품질, 여행 모빌리티 이용 시 발생 스트레스가 전반적인 여행 만족도에 어떠한 영향을 미치며, 특히, 모빌리티 이용 시 스트레스가 여행 만족도 형성에 갖는 조절 효과에 대해 검증하고자 하였다. 이 연구의 실증 분석을 위해 지난 1년간 여행 모빌리티 앱을 이용해 여행지를 이동한 경험이 있는 관광객을 대상으로 온라인 설문조사를 수행하였으며 부분최소자승법(Partial Least Square: PLS)을 적용하였다. 연구 결과 여행 모빌리티 품질과 여행 모빌리티 앱 품질은 전반적인 여행 만족에 긍정적인 영향을 미치는 것이 확인되었지만 스트레스 정도에 따라 영향력의 크기에 차이가 존재함을 확인하였다. 구체적으로 모빌리티 이용 시 발생한 스트레스가 클수록 여행 모빌리티 만족이 전반적인 여행 만족에 미치는 영향력은 감소하고, 반대로 여행 모빌리티 앱 만족이 전반적인 여행 만족에 미치는 영향력은 증가함을 확인하였다. 이는 여행 모빌리티를 이용함에 있어 받는 스트레스가 클수록 여행 모빌리티 앱의 효과를 강력하게 느낌을 뜻한다. 이러한 결과는 그동안 깊게 다뤄지지 않았던 관광객의 스트레스와 그에 대한 대처 방안을 이해하는 데 기초연구로서 그 가치가 있다고 할 수 있으며 향후 관련 연구에선 여행 모빌리티 외에도 명소, 숙박 등 여행지의 다양한 공간에서 발생할 수 있는 스트레스와 이를 관리할 수 있는 스마트 기술의 효과 검증에 대한 기초 자료로써 활용할 수 있을 것이다.

Design and Simulation of a Flow Mobility Scheme Based on Proxy Mobile IPv6

Choi, Hyon-Young,Min, Sung-Gi,Han, Youn-Hee,Koodli, Rajeev Korea Information Processing Society 2012 Journal of information processing systems Vol.8 No.4

Proxy Mobile IPv6 (PMIPv6) is a network-based mobility support protocol and it does not require Mobile Nodes (MNs) to be involved in the mobility support signaling. In the case when multiple interfaces are active in an MN simultaneously, each data flow can be dynamically allocated to and redirected between different access networks to adapt to the dynamically changing network status and to balance the workload. Such a flow redistribution control is called "flow mobility". In the existing PMIPv6-based flow mobility support, although the MN's logical interface can solve the well-known problems of flow mobility in a heterogeneous network, some missing procedures, such as an MN-derived flow handover, make PMIPv6-based flow mobility incomplete. In this paper, an enhanced flow mobility support is proposed for actualizing the flow mobility support in PMIPv6. The proposed scheme is also based on the MN's logical interface, which hides the physical interfaces from the network layer and above. As new functional modules, the flow interface manager is placed at the MN's logical interface and the flow binding manager in the Local Mobility Anchor (LMA) is paired with the MN's flow interface manager. They manage the flow bindings, and select the proper access technology to send packets. In this paper, we provide the complete flow mobility procedures which begin with the following three different triggering cases: the MN's new connection/disconnection, the LMA's decision, and the MN's request. Simulation using the ns-3 network simulator is performed to verify the proposed procedures and we show the network throughput variation caused by the network offload using the proposed procedures.

한국의 세대간 사회이동 : 출생 코호트 및 성별 비교

계봉오(Kye, Bongoh),황선재(Hwang, Sun-Jae) 한국인구학회 2016 한국인구학 Vol.39 No.3

이 연구는 한국의 세대간 사회이동 변화를 출생 코호트와 성별 비교를 통해 경험적으로 검토한다. 기존의 연구에 따르면 대부분의 산업사회에서 절대적 사회이동(absolute mobility)은 증가하다가 최근 들어 감소하는 경향을 보여주지만, 상대적 사회이동(relative mobility)에는 뚜렷한 패턴이 발견되지 않는다. 즉, 직업구조 변화에 따라 구조적 이동(structural mobility)의 양상은 변화하지만, 세대간 유동성(fluidity)에는 큰 변화가 없다는 것이다. 한국사회의 경우 급격한 산업구조 변동으로 인해 절대적 이동이 다른 국가들보다 높은 수준이며, 상대적 이동 또한 다소 높은 것으로 나타난다. 그러나 최근 들어 한국사회에서는 “수저계급론” 등 계층구조의 고착화에 대한 사회적 우려가 증가하고 있으며, 이는 계층갈등의 심화 및 사회적 신뢰수준의 저하로 연결되고 있다. 이러한 현상은 산업화가 일정 단계를 넘어서면 사회적 유동성이 오히려 감소할 수 있다는 “후기산업사회 경직화 가설(post-industrial rigidification thesis)”의 주장과 일맥상통한다. 이 연구는 절대적 이동과 상대적 이동이 사회이동 연구에서 갖는 함의를 고찰하고, 한국교육개발원의 “교육과 사회이동 조사연구”를 사용하여 세대간 사회이동 패턴의 출생 코호트별, 성별 변화를 살펴본다. 분석결과에 따르면 최근 코호트의 절대적 이동은 다소 감소한 반면, 상대적 이동은 크게 변화하지 않았다. 또한 통계적으로 유의하지는 않지만, 남성의 유동성은 다소 증가했으나 여성의 경우에는 감소하고 있다. 이는 사회적 유동성의 변화와 계층구조 경직성에 대한 인식이 일치하지 않을 수 있으며. 수저계급론 등과 같은 사회적 폐쇄(social closure)의 강화라는 단순한 개념으로는 사회이동의 패턴 및 계층구조 인식의 변화를 설명할 수 없음을 보여준다. In this study, we examine how intergenerational mobility changed across birth cohorts in Korea. Research in social mobility has found consistent relative mobility in industrialized countries as well as initially increasing and then decreasing absolute mobility during the socioeconomic development. Relative mobility in Korea was somewhat higher than other industrialized countries and absolute mobility was extraordinarily high due to high structural change. Recently, concerns about decreasing social fluidity increased, intensifying class conflict and dampening social trust. This phenomenon is consistent with the expectation of ‘post-industrial rigidification’ thesis; social fluidity may decrease at the late stage of industrialization. In this article, we critically review the implications of absolute and relative mobility in the study of social mobility, and examine how the intergenerational mobility patterns changed in Korea using the “Education and Social Mobility” data. While absolute mobility a bit decreased for the youngest cohorts, relative mobility showed no monotonic trends. We also find diverging patterns by gender; increasing rigidity among the women and increasing fluidity among men to some degree although these changes are not statistically significant. This suggests that the recent change of intergenerational mobility patterns in Korea is not simple and warrants more careful investigation.

컨조인트 분석을 이용한 공유형 개인 이동장치 주차장 선호도 분석

박유섭,오흥운 한국도로학회 2023 한국도로학회논문집 Vol.25 No.6

PURPOSES : This study is to analyze preference of shared personal mobility(shared e-scooter or shared bike) parking lot. The detailed purposes are as follows. Firstly, the attributes and attribute levels of shared personal mobility are developed. Based on combined attributes and attribute levels several profiles were composed. Preference data of shared personal mobility parking lot is collected through survey. Preference of shared personal mobility parking lot was analyzed using conjoint analysis. METHODS : Based on the literature review, the attributes and attribute levels that might affect behavior or intention of shared personal mobility parking were developed. Several profiles that contain combined attributes and attribute levels were created in a fractional factorial design. In order to collect preference data of shared personal mobility parking lot, online survey were proceeded. The survey participants were asked to mark preference point between point 1 and point 10. Lastly, preference of shared personal mobility parking lot was analyzed using conjoint analysis. RESULTS : Based on literature review, 5 attributes for conjoint analysis were set.(Distance between shared personal mobility parking lot and destination, Space for shared personal mobility parking lot, Location of shared personal mobility parking lot, Type of shared personal mobility parking lot, Interval of shared personal mobility parking lot). With the combination of 5 attributes and their levels, 16 random profiles were made. Online survey was proceeded with 300 participants who have used shared personal mobility. Using conjoint analysis utility and importance of each attribute has been calculated. As a result, the preference got higher when distance between parking lot and destination and intervals of parking lots are short. In addition racks are tended to be preferred and it seems to be more profer to install parking lot on buffer zone of pedestrian road instead of adjacent to private building. CONCLUSIONS : It could be important to install personal mobility parking lot considering preference of parking lot attributes in order to encourage users to use the proper parking lot instead of parking anywhere.
