Seoul's public bicycle system, 'Ttareungyi,' introduced in 2015, has achieved an annual ridership of 40 million in 2022. Similarly, electric scooters, a type of personal mobility device, surpassed one million riders in 2020 due to various sharing platforms. However, the major roadways for these new transportation, bicycle lanes, are notably insufficient compared to other forms of transport. Hence, this study proposes an optimal location selection method for bicycle lanes in Seoul to prevent accidents and enhance bicycle ride safety. The location selection process prioritizes road safety concerning bicycle accident risk. Using regression models, high-risk areas for bicycle accidents are identified. Cluster analysis categorizes these areas into six clusters, each suggesting suitable types of bicycle lanes based on cluster-specific characteristics. We hope that this study will contribute to the improvement of Seoul's transportation environment, including the expansion of dedicated bicycle lanes and lanes for personal mobility devices.

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.

The bikes are conflicted with the cars and the pedestrian at the intersection and the road with the bike crossing. To establish the bike signal at this section is one method to solve this conflict. According to the survey for the bike road status and the biker's characters which are crossing the road at the intersection, the bike crossing are established with beside the pedestrian crossing and most of the bikers are crossing the street by the pedestrian signal. Also, the bike queue which is waiting the signal change at the stop line was cleared before the closing the pedestrian signal. Considering the result of this survey, TOUCAN crossing signal type in England for bike signal at the place where the bike crossing are established with beside the pedestrian crossing, in which bike rider and pedestrian can cross by the pedestrian signal operation, is suggested. However, at the place where the bike crossing is apart from the pedestrian crossing, the bike signal which is connected to the vehicle signal is suggested. All these types of bike signals can be accepted for the present bike crossing equipments and the biker's characters and be adapted to the police standard traffic signal controller by adjusting the signal time only without any function change.

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.

This study investigates the effect on automobile traffic flow of the bike lane configuration via the road diet implemented in Nam-Gu, Busan using the microscopic simulator TransModeler. The results show that the increases in average delay time and stopped time experienced by automobile vehicles after implementing the road diet during the peak period are significant, but those during the non-peak period are insignificant at alpha=0.1. The results in peak period are consistent with the results of the past studies, which concluded that a road diet can contribute to deteriorating the level of service when the automobile traffic flow rate on the existing roadway is relatively high. For the non-peak period, the analysis results may reflect the fact that the automobile traffic flow is not severly affected by the road diet due to the reserved capacity.

10 years ago, Korea proclaimed the bike traffic activation law. Many cities have constructed bike paths and parking lots. However, because of increased bike users, lack of bike paths, and parking lots, it is predisposed to avoidance to ride. This study suggests reasonable bike parking lots scale and estimated bike parking lots using the bike traffic assignments. As results, reasonable bike parking lots scale is approximately 5% of car parking lots, which is minimum value. Then, each city can estimate reasonable bike parking lots scale by considering the characteristics and size of cities.

This study is to analyze the physical environment and conduct spatial data for bicycle road system in changwon. Index for evaluation index was developed based on literatures. Then the level of importance and weight have been modified through experts review. Finally, index with eight categories such as greenness(40% over), bicycle road connectivity(1.8, 9.8%), road type bike(bicycle lane, 24.4%), pave type(asphalt 72.5%), illegal parking(none, 93.9%), bike road surface visibility(exist, 46.8%), vehicle speed limits(30km, under), vehicle traffic(500/hr under, 44.3%) have been applied to empirical investigation. Collected data has been hierarchically classification by ArcGIS Program. The Highest grades(score 31-35, level 1) occupied 35% of target destination. High level of greenness and load type has contributed to high score. In addition, average level of greenness of those destination was 35% and higher, which provide high degree of security and freshness for bicycle riding. Meanwhile, lowest level(level 5, which earned 15 point or less) occupied 24.5%. illegal parking, low level of greenness, and no surface sign caused low score.

최근 그린 성장산업의 발전과 더불어 이슈화되고 있는 장애인들을 위한 전동휠체어와 일반인들의 자전거가 급격하게 보급되고 발전하고 있는 것에 반하여, 이동수단을 사용할 때 발생할 수 있는 위험으로부터의 대책은 예전과 전혀 다를 바가 없는 상황이라 할 수 있다. 이에 본 연구는 자동차 중심으로 개발되어 있는 네비게이션 기능과 그 서비스에 가장 적합한 도로 및 주변정보 콘텐츠를 전동휠체어와 자전거 중심의 시스템으로 재설계하여 그들을 위험으로부터 최소한의 보호하고 사고를 예방을 할 수 있는 전용 네비게이션을 개발하고자 한다. 본 연구에 의하여 제시된 연구결과가 자전거 사용자와 전동휠체어를 사용하는 장애인들의 생활을 더욱 안전하게하고, Slow-Moving 기기들의 보급 확장에도 도움이 되기를 기대한다.

2005년 리우환경회의 이후 지구환경보전을 위한 노력이 확대되고 이를 위한 친환경 교통이용에 대한 요구가 증대할 뿐만 아니라 고유가 시대를 맞이하여 승용차의 효율성, 편리성에서 시작된 승용차시대의 한계성이 최근 서서히 드러나고 있다. 뿐만 아니라 승용차가 교통문제해결의 수단이 되지 못하며 지구환경에 악영향이 확대됨에 따라 최근 친환경적인 자전거에 대한 관심이 증대되고 있다. 따라서 본 연구는 2010년 까지 만들어질 "자전거 전용 도로망 조기구축계획"에 따라 이용객의 편익을 위해 설치되는 자전거 정거장들의 최적지를 선정하고, 최적지 위치와 각 도로 환경에 대한 정보와 대화형 자전거 GIS 웹 서비스를 만들어 제공하는 것이 본 연구의 목적이다.
