본 연구에서는 공공자전거 코스 개발 및 국내외 공공자전거 시스템 조사를 통해 자전거 활성화 방안을 조사하였다. 대상지역 선정은 전주시의 관광 자원 개발을 위해 자전거 코스가 관광 코스와 연계될 수 있는 기존의 자전거 전용도로를 선정하였고, 각 코스의 구간별 현황을 분석하여 지역에 맞는 자전거 네트워크 시스템의 적응 가능성을 검토하였다. 실험에서는 지역 공공자전거 개발을 위해 전주시 자전거 코스의 문제점을 조사한 결과, 대상지까지 이동에 있어서 자전거 전용 도로와 인도 그리고 자전거 도로가 없는 구간들이 많아 실제로 이용하는데 한계가 있으며 구간별로 장애물과 좁은 도로 등으로 사고의 위험이 들은 것으로 조사되었다. 또한 국내외의 자전거 시스템을 종합 비교해 보면 RFID 및 PDA등이 적응된 유비쿼터스형 공공자전거 시스템 도입이 필요하고 이용자의 안전을 최우선으로 고려한 디자인 설계 및 공공자전거 그리고 각 지자체 자전거와 호환이 가능한 시스템 개발이 필요한 것으로 나타났다.

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.

The earth has been suffering from global warming and experiencing unusual weather caused by increased fossil fuel usage in the industrialization period. In spite of the continuous effort to resolve the problem, the amount of fossil fuel usage is increasing constantly. Public bicycle system has been introduced as a solution to the fundamental problem of the existing public transportation systems. Also public bicycle system has another advantage that riding bicycle can keep the users in good health. In this paper, a new ICT convergence public bicycle system is presented which resolves the problems of existing public bicycle systems. The presented system has strong points in low installation fee and low maintenance expenses. The effectiveness of the presented system will be proven by analyzing case studies.

In recent years, public bicycle systems are widely spread over the world according to the development of ICT technology. Since the public bicycle systems in large cities need to secure both publicity and convenience for citizens, analysis of various their issues from introduction to operation is required. In addition, it is also necessary to prepare for various scenarios for coexistence with the PM business, which is recently in the spotlight as a last mile means and normally managed privately. This paper introduces modeling and simulation for efficient operations of public bicycle systems. In particular, the proposed method was developed in a form that can be easily used in other cities by modeling the general structure and behavior of the public bicycle system, and it was developed to facilitate modification and expansion of the future model with a component-based model configuration. This paper provides a case study of the propose method, which is the public bicycle simulation in Sejong City. The simulation results were derived by applying the data from the public bicycle system of Sejong City, and they were verified with the associated real data of Sejong City. Using the verified model, it is expected that it can be used as a tool to design and analyze various services on the public bicycle systems, which were especially suitable for Sejong City.

Most of the developed countries and Korea have continued to invest much money in developing low-carbon vehicles such as electric car, methanol car and hydrogen car to replace the conventional fossil fuel vehicles. Government and local governments of each country, however, grope to construct roads for bicycle and public bicycle rental systems because bicycle is the only ultimate and feasible non-pollution transportation. Most of the current bicycle monitoring systems have achieved automation of rental process in bicycle stations, but they can not monitor bicycles in use. This paper develops GPS-CDMA modem combined terminals and implements a LBS-based bicycle monitoring system using them for public bicycle rental system. The monitoring system collects location information from GPS-CDMA modem combined terminals attached on bicycles and presents the moving tracks of bicycles on a GIS map for easy return and redistribution of bicycles. Also, the system helps to prevent from theft and vandalism of bicycles and to recommend the nearest bicycle station.

The world's major cities operate public rental bicycle systems to complement the existing problems of public transport in the city. Disclosing the rental history data in Daejeon has opened new analytical possibilities. In this paper, we proposed a method to analyze the data using the visualization. We found a positional feature of the station according to the bicycle usage. In addition, we examined the bicycle usage patterns according to the time/day/month. On the other hand, the usage patterns between each of the bicycle stations were identified through a path analysis. The specific objectives were identified through each stop destination ratio analysis. Based on these data, we suggest a direction of Daejeon public bicycle rental system development.

In this study, it is aimed to solve the problems of energy depletion, environmental pollution, climate change and traffic congestion in the coming generations. In Korea, the usage of public bicycle, which is a short-distance transportation system, is continuously increasing. Therefore, we analyzed the public bicycles of 'Taungryei' in Seoul and 'Nubiza' in Changwon City. We also conducted in-depth interviews with Stephen Anderson based on six principles of Creating Pleasurable Interfaces. As a result, users' discomfort was found in the functional part and the usability part of the public bicycle. Also, it was confirmed that the users were satisfied with the public bicycle in the meaningful part. Therefore, public bicycles should consider the user experience aspects to complement functional and usability parts for users.

Although there are continuous demands for activating BSSs(Bicycle Sharing Systems) due to the convenience and positive health effects, it is difficult to make a decision to support the existing systems and build more systems because of the deficit resulting from the operation of BSSs. Consequently, this study estimated the economic effects(WTP; Willingness to Pay) of BSS and analyzed the impact factors of WTP to support the above decision making in Daejeon. For this, we conducted a survey and collected 668 samples from the users and non-users of TASHU that is the BSS operated in Daejeon. Also, we used CVM(Contingent Valuation Method) for the estimation of WTP. The results show that the number of bicycle uses is a determinant factor having a positive relationship with WTP and car ownership and age are also determinant factors having a negative relationship with WTP. On the other hand, income and sex have no significant statistical relationship with WTP. Also, the economic benefit of TASHU was estimated as much as 49.9 billion KRW to 63.6 billion KRW. Considering the operation cost of 2.5 billion KRW, it is quite big benefit. Based on the results, it needs to support TASHU from a user perspective for the efficient operation of the system.
