Purpose: This study aims to estimate the demand for various public parking lots in Seoul by clustering similar demand types of parking lots and predicting the demand for new public parking lots. Methods: We examined real-time parking information data and used time series clustering analysis to cluster public parking lots with similar demand patterns. We also performed various regression analyses of parking demand based on diverse heterogeneous data that affect parking demand and proposed a parking demand prediction model. Results: As a result of cluster analysis, 68 public parking lots in Seoul were clustered into four types with similar demand patterns. We also identified key variables impacting parking demand and obtained a precise model for predicting parking demands. Conclusion: The proposed prediction model can be used to improve the efficiency and publicity of public parking lots in Seoul, and can be used as a basis for constructing new public parking lots that meet the actual demand. Future research could include studies on demand estimation models for each type of parking lot, and studies on the impact of parking lot usage patterns on demand.

The parking problem is caused by the parking demand. The ratio of parking demand at multi-family housing sites has been increased significantly, therefore several parking problems have occurred. The goal of this study is to investigate the parking demand per housing size of public-sized apartments, and to prepare that with the architectural regulations about parking supply. According to the results of this study, the parking demand of the small size housing unit(exclusive size：60 $m^2$ below) shows 1.09 car per the unit. and that of the medium size housing unit(exclusive size：60 $m^2$ over 85 $m^2$ below) shows 1.34 car per the unit. The parking demand of the small size housing unit was exceeded 56% more than the legal supply limit, and the parking demand of the medium size housing unit was exceeded 34% more. It is means that the level of architectural regulation about parking supply was not enough than the parking demand. So, it needs recon-sideration about the architectural regulations of parking supply.

After 1980's, the ratio of car possessions has been increased rapidly. Nowaday, most large cities have suffered a lot of problems about traffic and car parking. Specially in apartment complexes, they have parking problem which is caused by the parking demand. The ratio of parking demand at multi-family housing sites has been increased significantly, therefore several parking problems have occurred. The goal of this study is to investigate the parking demand per housing unit size of apartment complex in Daegu city. The results of this study is as follows. (1) The parking demand of 60 $m^2$ below sized housing unit is 1.09 car per the unit. (2) The parking demand of 60 $m^2$ over 85 $m^2$ below sized housing unit is 1.31 car per the unit. (3) The parking demand of 85 $m^2$ over 135 $m^2$ below sized housing unit is 1.74 car per the unit. (4) The parking demand of 135 $m^2$ over sized housing unit is 2.10 car per the unit.

Rapid urbanization causes a variety of transportation problems, including parking. Then transportation engineers would get involved in trying to solve parking problem. Estimation of parking demand is essential for finding a solution to the parking problem. Estimation of parking demand generally uses the "parking basic unit"; however, the parking basic unit does not totally determine parking demand. This study analyzes the problems with using the parking basic unit with a field investigation and the establishment of a new parking demand calculation model. Parking basic units estimated from the mean parking basic unit method are higher than those resulting from a regression analysis. However, parking basic units resulting from these methods fail to satisfy parking demand in many buildings. Analysis results for a cumulative distribution of parking basic units are reasonable if they satisfy 88% of parking demand in buildings. However, parking basic units that satisfy 88% of parking demand in buildings is a problem in some areas with an oversupply of parking lots. Ultimately, this study establishes a parking demand calculation model.

The purpose of this study is to propose reasonable standards related to securing the number of parking lots of university hospital in Korea. High proportion of visitors use their cars in order to receive consultation and treatment from doctors and feel the shortage of parking capacity of hospital, resulting to the low satisfaction level in using hospital. Of course, every hospital meets the parking regulation of the government. Therefore it is necessary to consider another parking demand factors besides the parking regulation of the government in order to secure proper number of parking lots in hospital. This study proposes number of hospital beds, vicinity of public transportation, number of doctors and staffs of hospital, and peak time parking demand as the parking demand factors.

Nowadays, there are many problems of traffic and parking in residential areas. This study begins analysis the parking situations in apartment complex. It originated from understanding of the parking preference of users about underground and ground parking lots. The method of this study is based on field survey of parking demand and thoughts of users of underground parking lot. There are so many parking problems in apartment complex that is due to the absence of parking demand data. So the goal of this study is to provide a solution of parking problems in apartment complex through understanding of the actual condition of parking problems, the preference and the reason of users about underground parking lot in apartment complex.

In order to improve the problem of parking which is getting worse day by day, the municipality carries out a survey on the actual situation of the parking lot supply and demand periodically according to the related law. However, in the existing evaluation method, the parking demand that occurs under the condition that the demand is suppressed by the parking supply and regulation due to the limit of the survey method is investigated. In addition, the analysis is conducted only for the present year, and prediction and analysis of future parking problems are limited. Therefore, we propose a method to evaluate the status of parking supply and demand, which is differentiated to improve the problem of the existing evaluation method. As a result, comparing the existing method with the improved method, it can be seen that the improved evaluation method can be useful for establishing the long-term parking policy for the improvement of parking problems.

The purpose of this study is to find a way of solving on parking problems at apartment complex through the trend analysis research of the parking demands according to the housing unit size. The subjects of this study are high-rise apartment complexes in Daegu city which are constructed within 10 years. The parking demand according to the housing unit size at apartment complexes had been surveyed every July for 4 years from 2000 to 2003. Specially, we knew that the parking demand of $85 m^2$ below sized housing unit at apartment complex was exceeded architectural regulation of parking supply, and the parking demand of $85 m^2$ over sized housing unit at apartment complex was kept within architectural regulation of parking supply. And, the estimating formula that can predict the future parking demand by the trend analysis according to the housing unit size at apartment complexes in Daegu city was gotten through this study. But, in order to get more accurate estimating formula, it should be based on data of funker research and investigation about apartment complexes and it should be studied continuously.
