The purpose of this study is to develop a parking behavior model in prior step for solv-ing parking problems in Pusan C. B. D. The results of this study are as follows; In the C. B. D of Pusan the peak parking time is between 2 and 3 o'clock P. M., and the average parking duration is 237 minutes. It means the use of parking lots is very ineffi-cient. Hence in order to shorten the parking duration, it is very urgent for drivers to chan-ge parking attitude. The walking distance from the parking lots to his destination is below 300∼500m, so the establishment of parking areas and the arrangement of parking lots in C. B. D should be planned on the base of the above walking distance. The model distinguishing between legal and illegal parking behaviors is derived from the binary decision model. The selected model has the correlation rate, η2=0.505 which is relatively high value This result shows that the detetminating judgement on the legal and illegal parking behavior is influenced mutually such factors as driver's occupation parking purpose monthly income distance to his destination averaged parking duration and age.

In this paper, a license plate investigation which is one of parking usage is performed. We survey research that should be given time interval using the camera without the observer. We assigned the investigation time interval to each of to each of the parking car, average parking duration is determined. Parking turnover, the number of vehicles of parking per hour per parking surface, is examined.

The aim of this paper is to analyze parking characteristics and demand of A general hospital(A hospital) based on data on entries·exits in parking lot and to improve parking service to patients and visitors without building new parking spaces. To improve the quality of parking service we analyze average parking duration, parking turnover, peak hour, parking index and parking demand of A hospital. Using the results of this research we can improve parking regulations and operate a parking lot smartly. Other hospitals of similar size of A hospital can also refer to these results to improve parking service and build a smart parking 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.

본 논문에서는 주차 시설 이용 현황 중에서 차량 번호판 조사를 통하여 평균주차시간과 주차 회전율을 구하도록 한다. 관찰하는 사람이 없이 카메라를 활용하고, 조사 시간에 일정한 간격을 주어 조사하도록 한다. 일정한 조사 시간 간격을 주차된 차량에 나눠주어 평균 주차 지속 시간을 구하도록 한다. 그리고 이렇게 하여 주차면 1개당 1시간당 주차 차량 대수인 주차 회전율을 구하도록 한다.

Tree box filters, an example of bioretention systems, were compacted and versatile urban stormwater low impact development technique which allowed volume and water quality treatment performance to be adjusted based on the hydrologic, runoff quality and catchment characteristics. In this study, the overall performance of a 6 year-old tree box filter receiving parking lot stormwater runoff was evaluated. Hydrologic and hydraulic factors affecting the treatment performance of the tree box filter were also identified and investigated. Based on the results, the increase in rainfall depth caused a decrease in hydrologic and hydraulic performance of the tree box filter including volume, average flow, and peak flow reduction (r = -0.53 to -0.59; p<0.01). TSS, organics, nutrients, and total and soluble heavy metals constituents were significantly reduced by the system through media filtration, adsorption, infiltration, and evapotranspiration mechanisms employed in the tree box filter (p<0.001). This significant pollutant reduction by the tree box filter was also found to have been caused by hydrologic and hydraulic factors including volume, average flow, peak flow, hydraulic retention time (HRT) and runoff duration. These findings were especially useful in applying similarly designed tree box filter by considering tree box filter surface area to catchment area of less than 1 %.
