In apartment type of housing, if resident's vehicle is registered in central control office and RFID TAG is issued, identification can be recognized from the time of entrance into parking lot and intelligent parking guide system can be activated based on the residents' profile. Parking Guide System leads a vehicle to the available parking space which is closest to the entrance gate of the vehicle's owner. And when residents forget where they parked their cars, they can query to the Parking Guide and Management System and get responses about the location. For the correct operation of this system, it is necessary to find out where the residents' cars have parked in real time and which lot is available for parking of other cars. RFID is very fancy solution for this system. RFID reader gathers the ID information in RFID TAGs in parked cars and updates the DB up to date. But, when non-residents' cars are parked inside apartment, RFID reader cannot identify them nor know the exact empty/occupied status of parking spaces because they don't react to RFID reader's query. So for the exact detection of empty/occupied status, we suggest the combined use of ultrasonic sensors and RFID. We designed a tree topology with intermediate data aggregators. The depth of tree is normally more than 3 from root (central office) to leaves (individual parking lots). The depth of 2 in tree topology brings about the bottleneck in communication and maintenance. We also designed the information fields used in RFID networks and Sensor Networks.

U-City에서 u-교통의 주차 정보 서비스 제공을 위해 주차 유도 및 정보 시스템을 개발하였다. 주차 유도 및 정보 시스템은 차량이 출발 전부터 최종 목적지 주차장에 도착할 때까지 운전자에게 주차장 정보, 주차 현황 정보와 최소 이동 경로를 실시간으로 제공하는 서비스로, 운전자의 주차 시간을 최소화하여 이용자 편익 증대, 교통 혼잡 완화 및 불법 주차의 감소, 주차장 관리의 효율성 극대화를 목적으로 한다. 본 고에서는 주차 유도 및 정보 서비스 시스템에 대한 고객 니즈 조사 분석 결과, 설계 및 시스템 구현 내용에 대해 서술하였으며, 또한 실제 주차장에 시스템을 구축하여 설치 전후의 주차 소요 시간, 차량 회전율을 비교 분석하였다.

최근 차량의 증가와 주차공간의 부족으로 주차를 이용한 사업이 늘어나고 있다. 주차사업에서 주차관제가 필수적인 요소가 되고 있고, 주차관제업체가 점점 늘어나는 계기가 되었다. 그러나 업체수가 점점 늘어나고 경쟁이 치열해 짐에 따라, 새로운 서비스를 창출하거나, 기술적 우수성을 가지거나, 현재 시스템 개선을 통해서 비용을 절감하려는 노력이 이루어지고 있다. 본 논문에서는 효과적인 주차산업을 위한 클라우드 기반의 자동차번호인식(LPR) 서비스를 이용한 주차관제시스템을 구현하였다. 제안하는 시스템은 구조적인 개선을 통해 비용을 절감하고, 설치를 간소화 하며, 장애나 업데이트시 빠르게 대응 가능하다.

GPS를 이용하여 이동 차량의 현재 위치를 정의하는 기술이 많이 연구되어 왔다. 그러나 GPS를 이용한 차량안내 시스템은 실시간으로 변하는 주차 상황과 도로 조건을 고려한 최적화된 주차 경로를 검색하는데 어려움이 있다. 또한, GPS 시스템은 고층빌딩, 지하주차장과 빌딩내부 도로에서는 동작하지 못한다. 반면, RFID를 사용할 경우 도심의 밀집지역내에서도 실시간 주차 및 도로 현황을 반영할 수 있다. 이 논문에서는 실시간 제약 조건을 고려한 RFID 기반 주차경로 안내 시스템을 제안한다. 구현 결과는 주차장 및 도로 정보의 변화를 즉시 감지한 후 새로운 경로를 적절히 안내할 수 있음을 보여 주었다. 이동 중 주차장이 만차일 경우 시스템은 즉시 새로운 경로를 재추출해서 고객의 모바일 단말기로 전송한다. 그리고 지정된 경로상의 도로가 갑작스런 사고나 공사 중일 때는 우회 경로를 안내한다. 제안한 기법은 진보된 통합 주차 관제 시스템에서 유용하게 사용될 것이다.

Rapid urbanization occurred a variety of transportation problems. Parking problem is one of the most problems of transportation problem then transportation engineers would get involved in trying to solve parking problem. A way to overcome a variety of parking problems needs preliminary data for conditions of parking but it lacks the preliminary data to do so. Thus this study analyzed a characteristic of a parking through a field survey for parking in Daegu Metropolitan City and Ulsan Metropolitan City. This study analyzed parking turnover, parking use ratio and parking basic unit for characteristic of a parking of each use districts and each cities. This study result reveals difference between the use districts' parking characteristic and cities' parking characteristic. Thus a close examination for use districts' parking characteristic and cities' parking characteristic is a prerequisite for a rational parking policy.

Recently, indoor air quality (IAQ) has been one of the major concerns of people. Indoor parking lots are subject to be exposed to high concentrations of air pollutants emitted from vehicles. This study was performed to investigate indoor air quality (IAQ) at indoor parking lots. Sampling sites were selected 5 indoor parking lots. Target indoor air quality parameters include a number of criteria pollutants such PM$_{10}$, CO, CO$_2$, and HCHO. In addition, a variation of IAQ according to ventilation system operating was measured at C site (underground parking lot). In general, all pollutants were maintained below indoor air quality maintenance standards. The indoor air quality at indoor parking lots was affected by the availability of the ventilation facility and their operation frequency. At the underground parking lot (C site) with ventilation system, TVOC concentration according to ventilation system operating were found to be lower operating (488.2 ${\mu}g/m^3$) than non-operating (1,401.2 ${\mu}g/m^3$).

The purpose of this study is recognized the problems of parking and parking demand, supply and operation of the control etc. It is to provide an alternative for the overall parking problem. Parking problem occurs because there is not enough parking spaces. In order to solve the parking problem of Chil-gok 1 residential development district, this study propose making use of a road parking lot establishment and the school playground and the public facilities construction parking lot. But it is the methods which are short-term. A fundamental solution method is Levying garage option on car buyers. It is system to apply a law for establishing garages to all of vehicles.

The system proposed in this paper is a fully automated parking control system that can even protect users' information through blockchain. Unlike conventional parking control systems, the system consists of a web page that is accessible to people of all ages and ages, directly to the parking lot. Such a system would also benefit managers in the parking lot business. This is because it can reduce soaring labor costs and maximize the sales it can generate by operating 24 hours a day. In order to implement these systems, the web page was first designed using HTML and the API was configured using JAX-RS to invoke the API required by the web page. As a result, it created a web page that was easily accessible to anyone, built a server that could be accessed by more than 200 people at the same time, focused on personal information protection by encrypting the information of users through blockchain grafts, and designed a system that enabled users to complete payments easily. It is planning to add QR codes and GPS functions in the future and implement a function that allows one-touch information on parking lots and their vehicle information.

The pattern recognition of automobile and parking line for the automatic car parking system was processed based on statistical method for reducing the processing time. The command of driving for parking at the vacant parking lot was transmitted from processor to motor driven actuator using direct sequence spread spectrum communication, which enables the multiple transmission in CAN(controller area network). The test-bed which has CCD camera, processor, radio transceiver and FPGA was implemented and demonstrated to be operated well.
