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 is a parking management system which uses mobile terminal equipment by the client. From the Web server, the client will be served about the information concerned with the location o( parking lot, parking time, and payment after accessing the parking management web site. After the sensor which is set in the parking lot perceives the information about the client's car, it will inform the client of the parking place. This system is designed to control the large and complex parking lot and serves a very convenient interface to the user.

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.

The parking area for the disabled is a parking facility for the pedestrian disabled and is a parking space for securing pedestrian safety passage for the disabled. However, due to the lack of social awareness of areas for the disabled, the use of parking areas is restricted, and violations such as illegal parking and obstruction of parking are increasing every year. Therefore, in this study, we propose a system to crack down on illegal parking in handicapped parking areas using the YOLOv5 model, a deep learning object recognition model to improve parking interference within parking spaces.

In this paper, we propose a parking information system which suggests an available parking lot on the shortest path between an entrance and adestination. In order to analyse the change of the parking management efficiency of each model as the number of unavailable parking lots increases from 10% to 99%, we compare the experimental results of three parking information system: an entrance-oriented system, a destination-oriented system, and the proposed system. Also, we compare user's satisfaction according to whether 50 user park their car with the proposed system or not.

Background : As parking problem caused by increasing owner-driver and patients concentrating to a general hospital is becoming one of the dissatisfactions in medical care. It is time that a general hospital should solve the parking problem in a desirable way. The purpose of this survey is to let the clients understand the basic motivation of the pay parking and develop the better parking system. Methods : Clients of a tertiary care hospital in Chon-ju were surveyed by means of a questionnaire. All in all, 193 subjects answered the questionnaire. Results : In relation to previous experiences, 39.6% of the subjects experienced inconvenience with confused parking lot and the shortage of parking space. Under the current parking system, the subjects who felt the available parking space was enough were more than those who didn't 62.7% of the subjects answered that they could find the parking lot easily. 33.2% of the subjects mentioned that it was not easy to drive in the parking area ; The reasons were pointed out the shortage of space, disordered parking, and insufficient guide. 12.8% of the subjects satisfied with the current administering system of parking lot. The outpatients were more affirmative than the admitted patients about the charging system. As for the parking fee, 64% of the subjects answered that it is expensive, and 89.5% of the subjects thought imposing of parking fee is irrational. Conclusion : To say as a whole, the basic purpose of the charging system are more or less accepted. However, the management details like parking facilities and payment method are dissatisfactory, so it is necessary to improve the management system. It is also noted that the inpatients showed more negative attitude than the outpatients with the charging system. To secure a more convenient parking, the parking system should be considered in relation to the information service, kind guidance, improve facilities, personnel cooperation, fix outpatient scheduling system, etc.

There have been many studies and technologies that define a current location of a moving vehicle with GPS(Global Positioning System). However, the navigation system with GPS has troubles to search an optimized route considering data such as realtime parking status and road conditions. Moreover, the GPS systems show malfunction in the downtown with very tall buildings, underground parking lot and the inside of buildings. On the contrary, the RFID systems are able to reflect real-time status of parking lots and roads in the downtown. This paper proposes a system of guiding path for parking lots to consider real-time constraints based on RFID. The results obtained from the implemented system show smooth guiding of a new route after immediately sensoring the change of the information of parking lots and roads: if a parking lot that a vehicle is heading to is fully occupied, the system re-searches a new route for a neighbor parking lot and immediately transfers it to customer's mobile, and if the designated route is under construction, the system guides a detour path. The proposed method will be useful for advanced integrated parking control system.

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.

To date, parking enforcement systems have only been used by parking enforcement authorities, who detect and penalize violators. This paper introduces a modified version of the parking enforcement system utilizing smartphones that allows ordinary citizens to report parking violators to parking enforcement officers. The procedures of the system are taking a picture of a vehicle in violation, receiving the violation report virtually and finally reporting if violation car still remained at same location after five minutes have passed. The proposed system contains properties for transmission and receiving data about whether the complaint report of the violator's vehicle has been received in real time. It also works in conjunction with the existing parking enforcement system. This paper describes implementation of the proposed system.

In this paper, for efficient parking control, in an Arduino environment, an intelligent parking control prototype was implemented to provide parking control and parking guidance information using HC-SR2O4 and RC522. The main elements of intelligent parking control are vehicle recognition sensors, parking control facilities, and integrated operating software. Whether the vehicle is parked on the parking surface may be confirmed through sensor or intelligent camera image analysis. Parking control equipment products include parking guidance and parking available display devices, vehicle number recognition cameras, and intelligent parking assistance systems. This paper applies and implements ultrasonic sensors and RFID concepts based on Arduino, recognizes registered vehicles, and displays empty spaces. When a vehicle enters a parking space to handle this function, the automatic parking management system distinguishes the registered vehicle from the external vehicle through the RC522 sensor. In addition, after checking whether the parking slot is empty, the HC-SR204 sensor is displayed through the LED so that the driver can visually check it. RFID is designed to check the parking status of the server in real time and provide the driver with optimal route service to the parking slot.
