Study of Design Standard Establishment of Vehicle Rotation Area in the Dead-end Parking Lot

Abstract This study points out a problem that the vehicle rotation area provided in a dead-end parking lot for apartment blocks is misused as unreasonable parking places but accordingly, the edge parking spaces are rarely used for parking. Therefore, this study aims to establish a parking design standard to improve the parking convenience andland-use efficiency by investigating the real parking behaviors and problems identified in the study area, multiple apartment blocks in Haeundae-gu, Busan. This study calculated two simple linear regression models for two mutuallyexclusive factors, such as the parking convenience and land-use efficiency, respectively, and specified a trade-off pointthat optimizes both factors. The study results found that parking convenience and land-use efficiency can be improvedby not only changing the misused vehicle rotation area to normal parking spaces depending on the usage pattern, but also by increasing the width of the edge parking spaces from 2.3m to 2.6m. Finally, this study suggests two parkingdesign cases for more realistic design applications by considering the parking environment in the dead-end parkinglot for apartment blocks.Key Words : Dead-end Parking Lot, Minimum Turning Radius, Parking Section, Regression Model, Vehicle Rotation Area
