This research aims to enhance the security and safety of bicycle facilities by utilizing convergence technology of ubiquitous sensor network in the transportation system. To achieve the aim, U-bike system has developed by utilizing sensor network technology, and the serviceability and safety function of public facilities in the system have enhanced. This research also presents a plan for the construction of U-bike using ubiquitous sensor network and safety infrastructure of facilities by analyzing bicycle traffic reports and characteristics of service through studying the literature on the security of bicycles and the safety of facilities on bicycle lanes. The result of this research will contribute to the enhancement of safety function of bicycle lanes and facilities around National 4 major rivers bicycle lanes in the future.

경제적인 풍요가 어느정도 이루어지면서 깨끗한 도시환경속에서 삶을 누리고자 하는 욕구도 증가되었다. 이를 반영하듯이 최근들어 환경에 대한 시민들의 관심이 어느때 보다 더욱 커져만 가고 있다. 이와 더불어 도시계획적 흐름도 물적계획에서 비물적계획인 인간중심 위주의 가치관으로 전환되고 있으며, 공원녹지체계의 정립, 도시경관관리방안, 자전거도로의 도입, 보행자도로의 계획과 설계, 대중교통의 활성화 등 많은 환경친화적 프로젝트들이 수행되어져 왔다. 본 연구에서도 기존의 주요 보행자공간으로 다루어져 온 보도공간에 대하여 조사연구하였으며, 도심의 외곽에 위치하고는 있지만 대구시의 남북을 관통하는 주요간선도로변에 접해 있고 보행량에 비해 보도가 지나치게 넓어 비효율적인 토지이용을 보이는 보도공간을 대상으로 하였다. 특히 도심의 외곽지 보도에 관한 연구는 통행량이 많은 도심지의 상업지나 주택지의 보도에 밀려 상대적으로 소홀히 다루어져 왔다. 이 가운데 대표성과 보편성을 가지는 곳으로 선정하여 연구를 수행한 결과 기존의 단순목적 보도공간을 4개의 공간 즉 보행자공간, 자전거도로공간, 차단 및 가로시설공간, 녹지 및 편익공간으로 재구성하였다. 이는 적은 비용과 노력으로 보행의 순기능인 쾌적성과 안전성을 보다 강화시켜나갈 수 있었다. 매연과 소음이 없고 도시민의 건강성를 확보한다는 이유로 여러 선진국에서는 수 년전부터 각광을 받고 있는 것이 보행교통과 자전거교통의 개념인 녹색교통이다. 이러한 녹색교통은 공해감소의 편익도 있지만 무엇보다 매력적인 도시환경의 창출과 인간중심적이라는 가치관에 그 의의가 있겠다.

South Korea is seeking for a solution to the problems of traffic congestion and environment: the increase of bicycle use. However many people feel that using a bicycle is inconvenient. Therefore, we developed bicycle level of service model from the user's perspective so that the existing bicycle roads can be evaluated and improved. The purpose of this paper is to develop a bicycle level of service (LOS) model by considering user's satisfaction and multiple factors that affect bicycle LOS. Bicycle LOS criteria is estimated by applying an ordered probit model, which is suitable for research relating to choice. In addition, we determine the bicycle LOS using three-level(A-C) LOS structure from the user position considering the satisfaction level that people can distinguish clearly. The results show that the bicycle LOS is largely determined by the bicycle road width. Other factors are involved as well, including bicycle road type, the number of access and egress point on the bicycle road corridor, pedestrian volume, and frequency of meetings.

In this study our main focus is to verify the relationship between social value of transportation system and its perceived features. To achieve this objective, we investigated the value of public bike system (PBS) through willingness to pay (WTP) analysis using contingent valuation method (CVM) and the survey was conducted for 1726 respondents who live in Suwon, Korea. Moreover the determinants related to features related to bicycle use were also gathered. The estimated binary logistic regression and censored regression reveal that the value of PBS is influenced by perceived features towards bicycle use incorporating non-congestion, transportation mode like auto and bus, and high mobility system as well as other variables such as income, bicycle ownership etc. Furthermore the results show that the perceiving of positive features to bicycle use leads to higher social value of PBS. Based on the findings, we discuss the importance of pre-review for transport policy implementation, and also explore the possibilities for application to PBS.

As the green transportation mode, revitalization of bike usage attracts remarkable public attention. For the acquirement of effective outcome, however, the concrete and close analysis about bike utilization characteristics should be arranged first. One result by MLTM(2009) is support this opinion; the bike mode share has been decreased whereas 9,170km of the bicycle path was improved(1995~2007). This study analyzed the bike mode share classified by trip types by using the 303,308 data of Household Travel Survey of Seoul Metropolitan Area, 2006. The highest mode share rate was induced by the institute attendee and Officetel resident as 3.75% and 3.13%, respectively. Also this study established the bike mode share estimation model of Seoul by logistic regression, and analyzed related factors and level of effectiveness related bike demand by calculation of odds ratio in terms of logistic regression coefficients. In conclusion, short trips, institutes district, parks, and Officetel residential area oriented policy should be effective on the revitalization of bike usage.

이 논문은 공공 빅 데이터를 활용하여 '서울자전거 따릉이'를 기반으로 자전거 교통 데이터베이스 시스템을 제작하고, 제작한 데이터베이스 시스템을 활용하는 예시를 보여주고 있습니다. 데이터베이스 시스템의 제작 과정을 통하여 데이터베이스 설계, 데이터 수집, 제작 및 가공 과정, 데이터베이스 시스템의 유용한 활용 예시를 확인할 수 있습니다. 버스, 택시와 같이 따릉이와 연계할 수 있는 다양한 대중교통 데이터를 추가로 활용한다면 더욱 정확하게 따릉이의 발전방향과 혼잡한 교통 환경 개선을 제시할 수 있는 유용한 정보를 도출할 수 있을 것이다.
