Central government and local self-governing bodies are actively promoting bicycle-riding as a solution for transportation, environment, energy and health. They put lot of efforts in the practice of bicycle-related policies such as building bicycle-related infrastructure and creating task force team to improve the bicycle-related systems. However, there is no substantive improvement in the city rail operation agencies regarding the bicycle-related facilities and operation. The expansion of bicycle-related infrastructure in city rail stations is urgently required considering the increase in demands from the bicycle-riders for the facility and bicycle-related service improvement. Accordingly, this study suggests a bicycle-riding vitalization plan linking the city rail and bicycle by providing with a bicycle custody place in the city rail stations which will have comprehensive convenience facilities including the safe-keeping facility for bicycles.

In this paper, the management system for a bicycle station using 900 MHz RFID technology has been developed. Based on the several reasons such as environmental pollution, high oil prices, and the government's eco-friendly policies, a bicycle usage is increasing nowadays. Accordingly, a need for bicycle parking spaces has already been emerging and increasing around a bicycle station. But most of the bicycle parking system are operated by manually, and it causes somewhat inefficient. Therefore, this paper suggests an unmanned bicycle station using RFID technology. The proposed system is supported by the mobile applications that are operated in the smart phones, and which gives the real-time access to the information of bicycle station. The proposed system yields owners of bicycle owners the convenience and efficiency of the station management in order to maximize the function of the bicycle stations.

As a solution for environmental problems caused by increasing number of vehicles, it is encouraged to use a bicycle as an environment-friendly transportation method. To vitalize the bicycle usage, it is a necessary to construct bicycle roads that are safe and suitable for users. Based on the previous research results, we assume the main purposes of bicycle usages are mainly local leisure activity and school commuting. Thus, the proposed method finds the shortest link between the existing bicycle road network and bicycle usage facilities such as leisure activity places or schools over public road network. Then, we carry out the RTK DGPS survey for the candidate links, and analyze the slopes of them. When the slope of a found link is larger than a threshold, an alternative link is re-found for the safety and convenience of a bicycle user. The proposed method is applied to the real bicycle road network in Mokpo, Chunnam and the results are discussed.

This study was carried out to present design guidelines for developing electric bikes which could be used for more users regardless of gender and age. Through a survey with 336 male and female respondents in Seoul aged between 10s and 70 years or older, the convenience of bicycle use and image preference by gender and age were investigated. To evaluate convenience of bicycle use, the 7 principles of universal design made by Universal Design Center were customized to fit for accessing bicycles. The following are results of statistical analysis on 301 valid data: (1) of the 7 principles, conventional bicycles were identified to be the most inconvenient in principle 6(low physical effort), followed by in principle 5(tolerance for error) and 7(size and space for approach and use). Women appeared to feel more inconvenience than men in all evaluation criteria while using bicycles. The relation between the convenience of use and users' age was not identified. (2) Preferred images by bicycle users turned out to be those of 'simple' and 'light.' By gender, male preferred more 'technical' and 'dynamic' images than female. By age, users in their 10s-20s preferred more 'individual' image than 70 years or older.

This paper is the product development of environment and safety. In growing society, the bicycle is need to have a common goals for consumers convenience and theft prevention. The bicycle is movable means. But as times passed, that bicycle is strongly recommended to replace other vehicles because that is not produced to air pollution and energy(gas, diesel etc) insufficiency. As workers using a bicycle are increased, road for only bicycle is made by additionary. The bicycles happens to several moving accidents such as car accidents because of signal mismatch between bicycle users. However, using the development products of this paper, many accident problems for bicycle can be solved. As increasing of bicycles numbers, the high cost bicycles are too increased. So, the more theft of bicycle is also happened. The developed products(turn signal system and theft prevention system) through this study kept your bicycles from more convenience and more safe.

In this paper, we propose a Bicycle sharing has grown popular around the cities in the world due to its convenience. However, the bicycle sharing system is not problem-free, and there remains many managerial problems to be solved. In this study, we analyzed pricing strategy of a bicycle sharing system by minimizing the number of bicycles relocated by trucks, the act of which incurs penalty. The objective function is constructed by applying mixed integer programming and is presented as a stochastic model by using Markov chain so that arrival and departure rates of bicycle stations can be utilized in the analysis. The efficiency of the presented model is verified upon the analysis of bicycle sharing data gathered in Daejeon in 2014.

This study aimed to devise the method to construct safe and convenient bicycle road by considering the peripheral environmental factor related to using bicycle. Analyzing the existing design of bicycle road and construction case, this study established the method to design bicycle road that reflects site condition and presented the optimal design method for each type of bicycle road to construct safe and convenient bicycle road by analyzing the type of traffic accident for each type of bicycle road, surveying present situation and local survey. It was found that the optimum design of bicycle road for specification, width, curve radius, ascending slope, etc in consideration of peripheral environment and separating traffic between users of traffic means should be done by installing safety sign, safe facilities and separation facilities to design safe bicycle road. Further, the minimum traffic space of bicycle users and connection between bicycle roads should be ensured to design safe bicycle road. It is judged that information related to safety and convenience of bicycle road such as slope, route information, location of convenience facilities, information to the public traffic should be provided so as to activate the users of bicycle.

The bicycle use activation plan reduces a greenhouse gas exhaust, and economic convenience, movement timely shortening, health effect will be able to expect but the bicycle user is few. The nationwide bicycle road projects is advanced by the countermeasure for a bicycle use activation. It is advanced a bicycle road basic plan even from each local government. The research against a route selection is advanced actively. But the research against a data process is not coming out the accurate research method. It follows a financial one bicycle road design standard from ministry of land, Transport and maritime affairs. But vertical grade in bicycle road design standard is exception becoming that about unavoidable case with geomorphic environments. From the research which it sees the existing bicycle road consider should have to make the terrain situation of yeosu, slope standard connection about under considering it presented the bicycle road route selection which is possible. It included a lane and road width with additional element and establishment in the bicycle road was produced suitable bicycle road route. The area where the mountain district is many when selecting bicycle road, will be used with application plan of slope standard.

This study deals with characteristics and risk of a PM based on user survey result, road driving test and data analysis of PM accident. Text mining method is applied to extract PM accident data from Big Data, which are claim data of private insurance company. Road driving test and survey on safety, convenience, noise, overtake ability, steering ability, and climbing ability of PM are performed to evaluate user's safety and convenience considering domestic road condition. As the result of claim data analysis, annual average increase rate of PM accident is 47.4% and average compensation of personal mobility is higher than that of bicycle by maximum 1.5 times. 79.8% of PM accident is self-caused accident due to unskilled driving and age-specific diagnosis rate of driver over 60 is higher than that of under 60. Diagnosis rate of over 60 at lower limb, foot, rib and spine is especially higher than that of under 60. As the result of road driving test and user survey, satisfaction level on safety and convenience of PM is evaluated as close to that of bicycle and satisfaction level of PM is increased after boarding. Overtake ability, steering ability, and climbing ability of PM are evaluated as same or better than that of bicycle but warning equipment to pedestrian or bike such as horn is required because noise level of PM during driving is too low. Finally, user survey result shows that bicycle road is suitable for PM and safety standard, advance-education and insurance are required for PM. It is suggested that drivers' license for PM can be replaced by advance-education. Results of this study can be used to prepare safety measures and legal basis for PM operation.

In this study, an evaluation index was developed and applied to derive indicators related to the environment for bicycle use and to evaluate the environment for bicycle use in the city of Suwon. Analysis showed that the relative importance between the assessment factors was highest in bicycle safety and that the relative importance among the assessment indicators was highest in terms of priority of items directly affecting bike riding, and items with indirect influence were low in importance. As a result of applying the evaluation model to bike paths in Suwon, it was confirmed that they can be described in a relatively realistic manner. The findings are expected to contribute to the development of local government directives for improving the environment of cycle paths.
