Parking infrastructure in university campuses has been inadequately developed in spite of rapid increase in car ownership of professors, staffs and students. However, only a few researches have been conducted domestically and overseas to identify and solve the problem. Thus, in this study owner drivers in 16 campuses located in Seoul Metropolitan Area were interviewed to figure out what they thought were important factors and how much they were satisfied when they were using parking lots in campuses. The questionnaires of the survey included economy, accessibility, convenience, punctuality, safety and informativeness. The Importance-Satisfaction Analysis was conducted based on the survey. And the parking characteristics of university campuses were compared based on the levels of importance and satisfaction calculated by ISA. Lastly, criteria of establishing campus parking management guideline were suggested as well.

The column gap of underground parking lots of office considering a business background and effective parking divisions is planned. A parking plan by column gap of fixed forms in atypical underground parking lots makes much extra storage rooms. Most of the edge of the parking lots are used for fan room. Part of the edge are located at parking ramps. Also warehouses are located in extra storage rooms. In this study compare study economical efficiency between life cycle costs and leases earnings. Consequently, It is proved that the warehouse rental is efficient because of lease earning guaranted years.

With the development of IT and digital camera technology, diverse applications of image processing services are becoming available. In this paper, in order to ultimately automate parking management system, we designed and implemented a system for recognizing vehicle license plates that show vehicles' unique numbers by using EmguCV which shows optimized performance on Intel-based environment. We also implemented UI for administrators to easily manage the entire system by utilizing.

무선 이동 네트워크 환경을 이용하여 특정교역에 산재해 있는 노상 및 노외 유·무료 주자창의 무인 요금징수장비를 실 시간으로 제어·관리하여 이용자에게 휴대용 컴퓨터 핀 셀룰러폰을 통해 정보를 제공할 수 있는 주차관리시스템을 제안한다. 본 논문에서 각 요금징수장비는 현재 상용화되어 있는 각 통신사의 PCS 또는 Cellular Phone의 COMA SMS(Code Division Multiple Access Short Message Service)를 이용하여 장비의 상태 및 제어 기법을 제안하였으며, 이 경우 추가적인 무선망 관리장비가 필요 없이 mobile phone만을 이용하기 때문에 아직 일반화되지 않은 고비용의 무선패킷통신을 대신할 수 있어 향후 S/W 교체만으로 전환 가능하여 보다 유용한 기법이 될 것으로 기대 된다.

Among the various application to use FRID, the parking control system widely uses it recently. However, it is rare for the existing systems to integrate several parking lot in the clustered shopping center. This paper proposes the integrated parking control system based on RFID. The system searches optimal path to parking lot with due regard to the position of users who own a tag and the status of parking lots. Then, it transmits the path to mobile devices of the users. The system consists of main server, middle ware to filter and manage tag information, parking lot client to send and manage the status of each parking lot and application module of mobile devices based on WIPI for displaying the optimal path. The main server integrates these components by a database and a new method to filters and manage tag information is newly proposed for the sake of maintaining the position and the direction of the cars in the middle ware. The implemented system shows that it is highly expected to be useful in an advanced integrated parking control system.

Recently all basement floor of apartment site have utilized as parking area to use efficiently space and to ensure lawful parking car figure. And the top of parking area has used as working vehicle's path and materials' carrying area during construction. Thus because crack and leakage status in underground parking area of under construction or completion building generate excessively not only performance of structure is diminished but also flaw repair cost is put in a lot of. And abroad confidence is diminish. So this study is intended to diminish flaw focus on investigation of under construction and completion fields through examine closely cause of crack and leakage status of apartment house underground parking area and prepare countermeasure with respect to design, construction and maintenance.

매년 도로와 주차공간의 확장보다 차량의 수가 빠르게 증가하여 그에 따라 불법 주차 관리의 어려움이 증가하고 있다. 이러한 문제점을 해결하기 위해 지능형 주차 관리 시스템이 필요하게 되었다. 본 논문에서는 획득된 차량 영상에서 수직 에지의 특징을 이용하여 번호판 영역과 개별 코드를 추출하고, 추출된 개별 코드를 퍼지 신경망 알고리즘을 제안하여 학습 및 인식한다. 본 논문에서는 차량 번호판 영역을 검출하기 위해 프리윗 마스크를 적용하여 수직 에지를 찾고, 차량 번호판의 정보를 이용하여 잡음을 제거한 후에 차량 번호판 영역을 추출한다. 추출된 차량 번호판 영역은 반복 이진화방법을 적용하여 이진화하고, 이진화된 차량 번호판 영역에 대해서 수직 분포도와 수평 분포도를 이용하여 번호판의 개별 코드를 추출한다 추출된 개별 코드는 제안된 퍼지 신경망 알고리즘을 적용하여 인식한다. 제안된 퍼지 신경망은 입력층과 중간층간의 학습 구조로는 FCM 알고리즘을 적용하고 중간층과 출력층간의 학습 구조는 Max_Min 신경망을 적용한다. 제안된 방법의 추출 및 인식 성능을 평가하기 위하여 실제 차량 영상 150장을 대상으로 실험한 결과, 기존의 차량 번호판 인식 방법보다 효율적이고 인식 성능이 개선된 것을 확인하였다.
