The purpose of this study is to analyze neighborhood environmental factors affecting bicycle accidents and accidental severity in Seoul, Korea. The use of bicycles has increased rapidly as daily transportation means in recent years. As a result, bicycle accidents are also steadily increasing. Using Traffic Accident Analysis System (TAAS) data from 2015 to 2017, this study uses negative binomial regression analysis to identify neighborhood environmental factors affecting bicycle accidents and accidential severity. The main results are as follows. First, bicycle accidents are more likely to occur in commercial and mixed land use areas where pedestrians, bicycle and vehicles are moving together. Second, bicycle accidents are positively associated with road structures such as four-way intersection. In contrast, three-way intersection is negatively associated with serious bicycle accidents. The density of speed hump or street tree is negatively associated with bicycle accidents and accidential severity. This finding indicates the effect of speed limit or street trees on bicycle safety. Fourth, bicycle infrastructures are also important factors affecting bicycle accidents and accidential severity. Bicycle-exclusive roads or bicycle-pedestrian mixed roads are positively associated with bicycle accidents and accidential severity. Finally, this study suggests policy implications to improve bicycle safety.

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.

This paper proposes a corresponding bicycle fitting method through a number of clinical results and experiments, with the aim of standardizing the comprehensive bicycle fitting method with the aim of developing a system that incorporates bicycle fitting software and hardware to proceed more precisely and quickly. This bicycle fitting method can determine the value of bicycle setting for the rider through in-depth counseling, bicycle check, sophisticated body sizing and analysis, and from the bicycle adjusted to this setting, the posture and pedaling torque can be analyzed through fixed lading, which can be followed to find the most efficient setting value and optimize the bicycle to meet the needs of the rider. Such a fitting method can increase the satisfaction of bicycle riders and also be expected to prevent injury through accurate bicycle setting values. This paper can be established as a bicycle fitting technology that can be recognized even in the global market if the final bicycle fitting system is implemented as the result presented in the most concrete domestic and foreign countries.

PURPOSES : Recently, there are increasing bicycle accidents along with increasing bicycles users. Bicycle accidents occurred frequently by perpendicular collision form at intersection inner. In order to improve safety of bicycle, drivers need to be aware of bicycles on the road and intersection geometric designs need to be designed to reduce risk associated with collisions between bicycles and car. This study aims to review the location of bicycle crossing in the viewpoint of bicycle safety. METHODS : Four types of bicycle crossing by curve radius and driver's check around the behavior are set to simulate the risk of collisions between bicycles and car turning right. Simulation using fortran programming are conducted on total 60 cases. RESULTS : Bicycle crossing located behind of crosswalk is lower the risk of collisions with car in all cases. In addition to the larger curve radius of pavement edge at intersection and the more pay attention to the rear by the turn head to the right is too low the risk of collisions with car. CONCLUSIONS : It is show that the location of bicycle crossing is safer behind than in front of crosswalk in the viewpoint of bicycle safety.

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.
