In recent days, mart or department which have large parking lots provide service for finding parked cars using NFC and GPS technology. In case using NFC, users should directly tap NFC tag, and GPS does not work inside the parking garage. In this paper, garage parking indicator system using becoan served push notification is described. By using this system, users can automatically be aware where they parked car when they enter into the huge parking lot. This system overcomes the weakness of the existing parking indicator systems, such as using NFC tag system and using GPS system.

With the recent increase in the number of cars and the lack of parking spaces, the number of parking businesses has increased. the parking management has become an essential element in parking business, and the parking management's company becomes an increasingly popular opportunity. However, as competition grows as more and more and companies increase in number, efforts are being made to create new services, gain technological excellence, or reduce costs through current system improvements. In this paper, we developed a parking management system using cloud based LPR(License Plate Recognition) service for effective parking. Structural improvements in the proposed system reduce costs, simplify installation, and respond quickly to failures and updates.

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 the urbanization progresses, the demand for parking in large cities surges compared with that for parking lots. However, the space for securing a parking lot in a large city is physically limited and a budget problem also arises. Therefore, a shared parking system that can utilize existing parking lots is becoming important. This study was carried out to analyze the parking area efficiently for the residents parking area. As a result of the questionnaire survey, it was the most frequent passage to work / commuting and business purposes. The most important factors in parking were 'Parking charge', 'Walking distance to the destination after parking', 'Parking lot searching time' Approximately 46 % of the respondents were female. As a result of the quantitative analysis of the factors influencing the potential use of the intention to use as a dependent variable, it was analyzed that the policy was effective to reduce the parking fee to less than 500 won per 10 minutes and take about 3-6 minutes to search.

In this paper, we proposed A Study on Construction of Infrastructure for Handicapped Parking Areas Using RFID. This paper is Construction of the Handicapped Parking Areas infrastructure Using RFID with 900MHz band, and researched the optimal position of the tag attached on the vehicle and the location of RFID reader in order to raise the efficiency of RFID reader and the recognition rate by the handicapped vehicle. The result of research is shown the optimal position of RFID reader establishment when the height of RFID reader is 170cm in height and the angle of $80^{\circ}$ with the ground when the vehicle traveling direction of the antenna and the RFID reader when the surface and the angle of $90^{\circ}$ showed the best position RFID readers installed. Parking spaces for the disabled in accordance with these results the RFID readers installed and it works in conjunction with enforcement camera car tagged crackdown on vehicles and other general management, the system is built to allow handicapped parking spaces that meet the intent of the original purpose being used as expected to contribute significantly.

A method of individual vehicle detection using gray scale image acquired from a high position is proposed for guidance of incoming vehicles to vacant cells in a parking lot and other similar purposes. With the proposed method, each image region corresponding to a cell is fragmented according to density(gray level), and the distribution of segment area is analyzed to decide if a vehicle is present. The proposed method was tested on an actual outdoor parking lot during 2 days with different weather conditions from sunrise through sunset.

The final step of driving a car is parking, which is the most difficult part for people learning to drive. Parking in narrow parking spaces is difficult for both ordinary drivers and beginners. To solve this problem, the development of SPAS (Smart Parking Assist System), ACC (Automatic Control System) improves the convenience of drivers. In addition, parking assistance systems have been developed to recognize more accurately the surrounding environment to the driver using the ultrasound, camera, thermal camera, and radar. This paper proposes the reverse turning radius to process images as if the camera is located in the center of the vehicle regardless of the actual camera position. In addition, it generates the parking guidelines through verification using the vehicle.

본 논문에서는 일방통행 도로에서 보행자 공간을 확보하고 주차 공간을 확보하면서 도로의 소통을 원활하게 할 수 있는 장점이 있음에도 불구하고, 차량 우회 거리의 증가나 회전 용량의 감소 등으로 인한 불편함도 있기 때문에 일방통행 지정은 기술적으로 매우 신중할 필요가 있다. 일방통행 도로 중 주민들의 변경 요구가 강하고 일방통행의 지정 목적을 달성하기 어려운 도로는 물리적인 여건이 허락되는 범위 내에서 양방통행으로 바꾸는 것이 바람직하다. 이 연구에서는 연구의 목적을 달성하기 위해 현재 운영되고 있는 일방통행 체계를 현장 조사하여 검토하고, 주민들을 대상으로 일방통행 체계에 대한 설문조사를 실시하여 주민들의 의견을 취합했다.

The parking management system can increase driver's convenience with detailed parking information service in the parking lot. At the same time, parking management system consumes non-negligible electrical energy with large amount of sensors, displays and control modules. With the increase in the demand for green and sustainable building design all over the world, it becomes a meaningful issue for parking management system to reduce operating power. This paper presents the preliminary design and estimated results of a parking management system which is optimized to reduce the power consumption mainly on detectors and displays. The system design is based on pre-developed wireless parking detectors, Park Tile and Park Disk. The system has a number of parking space detectors, vehicle count detectors, information displays, guidance terminals and other control units. We have performed system architecture design, communication network design, parking information service scenario planning, battery life regulation and at last operating power estimation. The estimated operating power was 0.93KW per parking-slot, which is 20% of traditional systems. The estimated annual maintenance cost was 18% of traditional systems.
