Recently, the number of cars owned in Jeju Island and the use of tourist rental cars have been increasing rapidly. Therefore, parking problems are getting worse in residential and commercial areas. As a result, a system is required to secure parking spaces and utilize existing parking spaces. Therefore, this paper proposes a system for real-time sharing of free public and paid parking spaces by introducing services that provide information on nearby restaurants, tourist information, and real-time parking status. The system analyzes infrared sensors and CCTV images installed in the actual parking lot and provides convenience for service users by analyzing the space currently in use and the number of unused parking spaces in real time.

As IT has developed, it provides the convenient facilities in human's life. However, previous parking information systems serve only few things. such as to automatically issue a parking tag, and to show the number of available parking spaces. In this paper, we propose a parking information system providing the shortest way to go to the recommended parking space as well as the abilities served by the previous systems. By utilizing this shortest way information, a driver does not need to hang around a parking lot in order to look for the parking space. Because a parking lot manager can understand the parking lot state by using this system, he is able to deal with any trouble quickly. Therefore, the proposed parking information system reduces both the parking management cost and the number of staffs for the parking lot.

Due to the development of cities and the increase of vehicles, effective control of parking space management service in cities is needed. However, the existing parking lot management system does not provide limited or convenient service in terms of space and time. In this paper, we propose distributed parking space management service based on large scale LPWA (Low-Power Wide-Area). The parking sensor collects parking space information from the parking lot and is transmitted over a low-power wide network. All parking data is processed and analyzed in the IoT cloud. Through a parking space management service system in all cities, users are given the temporal convenience of determining the parking space and the area efficiency of the parking space.

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.

At the present, planning and installation of parking space sections and lane width are implemented in accordance with the installation standard and parking lot structure by the enforcement regulations of the Parking Act. While large and RV (Recreational Vehicle) vehicles have increased in number recently, parking is complex with improper installation standards. It causes serious problems, including vehicle vandalism, increased civil complaints, travel inconveniences for parking lot users, management and maintenance issues for parking lots, and so forth. The study, therefore, determined that the practical and appropriate realignment of parking unit adjustment and lane width regulations are essential. The study conducted prior review on domestic parking sections and change cases of composition by vehicle types, including the component ratio of domestic and foreign vehicles, width of vehicle by types in order to examine the parking problems that account for a increasing social issues, and provided parking plan methods by types of vehicle, as well as reform and reaction plans for parking unit adjustment and lane width considering security and smooth traffic flow. After comparing and analyzing between estimated installation of parking space and lane width and internal and external cases, the study suggests the improvement that considers expenses and convenience of a driver. Also, it shows installation of parking space that considers traffic safety, improvement of lane width, and parking way depends on vehicle types. By providing estimation for parking planning and parking planning methods that secure safe and smooth traffic flow within a parking lot, the study will contribute to the development of improved alternatives for cost-effective traffic safety and set-up structure, including installation standards of parking lots.

The number of vehicles registered in Korea is rapidly increasing and will reach 18.26 million as of June 2011. The rapid increase of large-size passenger cars and RVs among this number is causing damage to other vehicles when parked in currently installed parking lots, increased civil complaints from the damage, and inconveniences to people trying to pass through parking lots as well. In particular, the car-stoppers indiscriminately installed at the parking lots are also causing accidents and adding to parking problems, causing economic losses. Accordingly, there should be new regulations for the amount of parking space per vehicle and for locations to install the car-stoppers. The research has first reviewed the distribution ratio of vehicle models from home and abroad for the width and length of the vehicles by each model, parking space per vehicle where the car-stoppers are installed and examples of changes in distribution ratio. In addition, the amount of parking space per vehicle was calculated with consideration for various specifications by each car model. As a result, margin width of full sized car is decreased by 18~21mm on the existing width. This is judged decreases accident of parking lot, because length of the front of car is not deviate parking Space Section. In conclusion, presented improvement ideas for parking plans with enhanced convenience and safety from the aspect of the drivers. Parking lot relevant businesses will also be maximized in terms of cost and efficiency when the criteria for the structure of parking lots and their installation is established and the improved parking plan is applied in the future.

The purpose of this study was to investigate the differences in the characteristics of the aesthetic salon operation and job satisfaction according to important considerations in opening aesthetic salons as well as to provide basic data for improving the operation of the salons. Toward this aim, a questionnaire survey was conducted for owners of small aesthetic salons across South Korea from January-March, 2016. Results were as follows: Among those who identified means of transportation and parking convenience as key considerations in launching aesthetic salon businesses, length of service, length of business operation, monthly fixed revenue and proportion of the highest profit were highest. Job satisfaction (F=3.223, p<.05) was highest (M=4.11) among those that responded 'floating population' as a primary component in launching aesthetic salon businesses, and lowest among owners who mentioned 'cost of investment' (M=3.41). Specifically, job mobility (F=2.960, p<.05) was the highest among respondents who selected means of transportation and parking convenience (M=3.95) as key criteria in launching aesthetic salon business. For the stable operation of an aesthetic salon, a location with high floating population, good transportation, parking convenience, high levels of customer access, and job satisfaction are critical factors. In addition, future studies should examine marketing strategies by operating characteristics.

According to the change of life environment and economic growth, the more city has highly developed, the more concentrated urban function. That is, city is required for adding infra structure. But, both of limited land resources and financial problems made it impossible to add infra structure. So, the necessity of multi-dimensional planning of urban infra structure was recognized. Especially, In Urban residential area, in order to secure parking area, It is on the increase that mixed-use of the playground of school in the high density area and the empty space of park. School and park is closely connected with town community, playing a central role on town life. For this reason, they are highly demanded for providing space in the urban residential area and also expected to be effective. However, people using park and school are almost young students and the elderly, it needs to consider not only the parking convenience also the safety of users in design process. In this study, we analysed the physical characteristics and the utilization of mixed-use of school and park. and then evaluated the case in the point of convenience and safety. For this, first we selected the case among the sites constructed in seoul, and divided 2type of 'slope type' and 'flatland type'. The meaning of this study is to suggest elementary standards for design in the point of multi-dimensional land use planning.
