s economic development has been achieved and society gets complicated, problems of traffic system have been also exposed. Due to these problems, drivers have to endure economic loss and delayed time. A web-based parking lot management system has been proposed to solve this problem. Because a parking lot is an important resource of traffic system, efficient management of parking lots can be means to solve critical problems of traffic system. In this study a simple method is introduced to detect moving vehicles with geometric information of moving objects that has been computed from surveillance cameras installed in a parking lot. Statistical information processed from image data is also stored on a server side, such as total number of parking lots, a number of parked cars and a number of available parking spots. A client who wants to know the nearest parking place can share the information via a mobile device and shorten his or her driving time. Great benefit to both drivers and society is expected if many parking lots are equipped with this system.

This paper researches on securing parking spaces and improving parking performance, by use of vehicle license plate investigation for average parking time and parking turnover ratio. Even though general surveys on vehicle license plate investigation are performed by the person, our survey is performed by the machine, CCTV. Unusually, our method checks average parking time and parking turnover ratio at time intervals of the survey. So, it is easy to check whether a parking lot is effectively used and its traffic flows smoothly or not. In our experiment, we exclude a method to recognize characters by use of 4-direction projection.

최근 울산항에는 화물차가 정해진 화물차 주차장이 아닌 항만 내외에 불법주차를 하는 사례가 빈번하게 발생하고 있다. 본 논문은 이러한 문제를 해결하고자 화물차 주차장 이용을 활성화하는 방안을 연구하였다. 이에 따라 화물차 주차장의 주차 현황을 실시간으로 제공하는 딥 러닝(YOLOv4) 기반 영상분석방식의 스마트 항만 주차정보시스템을 제안한다. 더불어, 제시한 방안을 통해 주차장 이용이 활성화 되었을 때의 사회적 가치를 산정하여 기존과 비교하였다.

Recently, due to advances in both imaging technology and ICT, various types of image processing services became available and the application services of these two technologies are diversifying. Recognition of vehicle license plates is used in places where vehicle information is needed such as in parking management. However, existing systems have economic disadvantages like issuing parking tickets and attaching unnecessary equipment. In order to solve these problems, we designed and implemented automatic parking management system through recognition of vehicle license plates by using emguCV that is based on OpenCV. Additionally, we designed improved UI to handle the entire parking management situation which include information such as details of each parking vehicle, parking time and remaining parking spaces without screen movement. This improved UI is implemented with the use of WPF which is the latest technology in user program development. The emguCV used in this paper showed the most optimized performance in Intel based environment. With it, we obtained the result of within 0.5 seconds of recognition processing time and over 90% of recognition rate. Through improved UI, the manager could both simply and intuitively manage the entire system.

This paper is concerned with optimization of a motor torque to drive Parking Sign system. It needs to minimize powers for stand alone operation and requires the optimized parameters in order to move the plates in the minimum torque. The operation can be represented as a complicated non-linear equation which is difficult to solve by general optimization techniques. In this paper, the dynamic equations of the system are derived, also the suitable Genetic Algorithm is designed to solve the equations. Computer simulation shows the availability of this method.

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.
