  • This study analyzes the physical environments of studio-housing and suggests alternative solutions for the problems of studio-housing. Based on solving the problems of it through previous research review, the research methods are decided on-site survey and the housing floor plan analysis. The results of this study are follows. First, parking lots make passengers uncomfortable. Narrow spaces between buildings cause problems in terms of light, ventilation, and privacy. Moreover, the short of green space makes living conditions less amenable. Second, the narrow corridors of studio-housing buildings bring about bad effects on walking and privacy. The living conditions becomes worse due to the illegal remodeling. Third, even though a multi-family housing provision for low or middle-income families is a good housing policy, new design policies or interventions are needed to make residents' behavior comfortable.

  • The vehicle license plate recognition (VLPR) system analyzes and monitors the speed of vehicles, theft of vehicles, the violation of traffic rules, illegal parking, etc., on the motorway. The VLPR consists of three major parts: license plate detection (LPD), license plate character segmentation (LPCS), and license plate character recognition (LPCR). This paper presents an efficient method for the LPCS and LPCR of Korean vehicle license plates (LPs). LP tilt adjustment is a very important process in LPCS. Radon transformation is used to correct the tilt adjustment of LP. The global threshold segmentation method is used for segmented LP characters from two different types of Korean LPs, which are a single row LP (SRLP) and double row LP (DRLP). The cross-correlation matching method is used for LPCR. Our experimental results show that the proposed methods for LPCS and LPCR can be easily implemented, and they achieved 99.35% and 99.85% segmentation and recognition accuracy rates, respectively for Korean LPs.

  • 본 논문에서는 전기차 파생 IT융합 서비스의 일환으로 원활한 전기차 충전을 지원하기 위한 불법 주차 방지 시스템을 제안한다. 국내 전기차 관련 법에 따르면 전기차 충전소 앞에 전기차가 아닌 일반 차량이 불법으로 주차를 하게 되면 과태료를 내게 되어 있다. 따라서, 제안한 시스템에서는 전기차가 아닌 일반차가 주차를 하면 경광등 작동시켜 운전자에게 경고한다. 제안한 시스템에서는 딥러닝 기반의 영상인식 SW를 적용하였다. 다양한 조도 환경에서 인식 성공률을 분석하였고 어두운 저녁에는 주변 광량에 따라 인식이 잘 이뤄지지 않는 것을 확인하였다. 향후 추가 LED를 더해 광량의 부족함에 따른 인식률 저하를 개선하는 연구를 진행할 계획이다.

  • 전 세계적으로 도시화가 가속화됨에 따라 도시 내 차량의 수가 지속해서 증가하고 있지만 주차 공간의 부족으로 인해 도심 내 불법주차 문제가 심각해지고 있다. 또한 주차된 차량의 운전자 정보가 노출된 환경으로 인해 개인 정보 유출이 중요한 사회적 문제가 되고 있다. 따라서 본 논문에서는 불법주차 해소와 운전자 개인정보 보호를 동시에 해결하기 위한 자율주행 로봇 시스템을 제안한다. 제안한 방법에서는 정상 주차를 식별하기 방안으로 마커 인식을 적용하였고 ROS 기반 Stella N1을 사용하여 자율주행할 수 있는 로봇을 제작하였다. 또한 전화번호 없이 운전자와 연락을 취할 수 있는 메시지전달 앱을 개발하였다.

  • As shared electric kick scooters spread to cities worldwide as a result of the proliferation of personal mobility, they have emerged as a significant social issue, impacting pedestrian and user safety, as well as urban aesthetics. In this study, we propose solutions to the unique problems associated with shared electric kick scooters, such as illegal parking, charging, and redistribution. Furthermore, we present research on supplementary services utilizing electric kick scooters in urban areas to enhance citizen safety and user satisfaction through the development of an autonomous electric kick scooter system structure and operational strategies. We suggest a low-cost autonomous electric kick scooter structure and propose AI processing, sensor fusion, and system operation methods to add autonomous capabilities to affordable electric kick scooters. Additionally, we propose operational systems and related technologies for offering various supplementary services.

  • 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.

  • In this paper, we proposed the new vehicle license plates detection method which is available in a various fields, including vehicle access control, illegal parking and speeding vehicle crack down. First, we binarize an image by using difference of gaussian filter to find a sequence of numbers of plates. Second, we determine the plate region by labeling repeatedly using the morphological characteristics of the plates. Finally, we use a projective transformation for correcting the distortion that occurs because of the camera or the location of the vehicle.

  • PURPOSES : In this study, the effects of when median exclusive bus lanes were applied to Daejeon trunk road (Wolpyeng crossway~Seodaejeon crossway, 6.3km) and (Daeduck Bridge 4~Kyeryong 4, 2.6km) by Microscopic Simulation VISSIM (5.0) was studied. The median exclusive bus lanes are one of the measures of transportation system manage techniques that can especially improve the efficiency of public transportation facilities. METHODS : According to the analysis of VISSIM on the Gyerong mainroad and Daedeok mainroad, when the median exclusive bus lanes were applied unlike when the roadside bus-only lanes were applied, the average travel speed of vehicles decreased but the average delay time and travel time increased. This arised from the changes in the geometric structure of the road which occurred the reduction of vehicle lane in the center of the road. RESULTS : In the case of bus, on the other hand, the average travel speed increased but the average delay time and travel time decreased. This is because the problems such as illegal parking and stopping, secondary road in out vehicle, and conflict of intersection right turn that roadside bus-only lanes occurred was solved. CONCLUSIONS : Although the introduction of median exclusive bus lanes will have a negative effect on general traffic flow due to the aggravation of travel, decrease of passenger car usage will lead to decrease of traffic volume. Therefore, smooth vehicle travel is expected.
