    Abstract PDF
    This study aims to evaluate the driving safety and mobility of personal mobility devices and to derive the correlation between driving characteristics and driving environments, focusing on the First Neighborhood District of the Multifunctional Administrative City. For this, the study presented a methodology to evaluate the driving safety and mobility of personal mobility devices, and measured acceleration and speed in the driving process after selecting normal bicycles, electric bicycles, and e-scooters as driving test devices. Then, the study conducted correlation analysis, cluster and outlier analysis, and multiple regression analysis in order to understand the effects of driving environments on driving characteristics. As a result, the research reached the following conclusions. First, regardless of the type of personal mobility device, the correlation between driving safety and driving mobility was found to be low overall. Next, the effects of driving environments on driving characteristics differed for each type of personal mobile devices. In terms of driving safety, e-scooters were more affected by road surface environments than electric bicycles. On the other hand, in terms of driving mobility, in addition to road type variables, situational factors such as competition with pedestrians and other personal mobility devices were also judged to be important.

    Dynamics on the Spatial Relationship between the Main Commercial Area and Adjacent Commercial Areas: A Case Study of the Hongdae Commercial Areas

    Abstract PDF
    A commercial district, the core of urban economic activity, continuously changes in its spatial structure. The spatial changes not only occur inside the district within a fixed boundary, but also affect adjacent commercial areas. Regarding this, previous studies have not systematically investigated a detailed dynamics of the spatial interactions and the underlying mechanisms based on a large-scale empirical dataset. To enhance the understanding of spatial interactions in commercial districts, this study utilizes the long-term-scale, esablishment dataset and explore the spatial dynamics in commercial districts in Seoul from 1999 to 2019. The study particularly focuses on understanding how adjacent commercial districts spatially change and interact with each other through the lens of existing urban theories. The results capture three patterns in the spatial dynamics: 1) the existing main commercial core continuously expands its spatial boundary, 2) the nearby small commercial cores gradually lose their centrality as the main core strengthens, 3) a new core appears in the very vicinity of the main core, and it rapidly develops. This study confirms that the influence of main commercial area can be strengthened, while adjacent commercial areas can be weakened according to the dynamics of positive feedback in the relationship between the main (high hierarchy) and adjacent (low hierarchy) commercial areas.

    A Study on Feasibility Assessment System Improvement Considering Balanced Regional Development: Focusing on the Industrial Complex Development Project

    Yeo Kyodong , Song Jiyoung | 2022, 113() | pp.43~56 | number of Cited : 0
    Abstract PDF
    The purpose of this study is to develop a method to reflect the value of balanced regional development that has been neglected in the feasibility study of the Local Finance Act. Accordingly, a vulnerability assessment model was developed for the industrial complex development project, which is considered to be the most representative project contributing to balanced regional development, and a plan to apply it to the feasibility study system was prepared and reflected in the related guidelines. To this end, six industrial complex-related candidate indicators were set, and weights were derived by finally selecting four detailed indicators through expert surveys. In addition, a standardized score calculation formula for each indicator was developed to derive the vulnerability evaluation scores for the industrial complexes of 167 local governments. This study lays an important framework for quantitatively reflecting social values through objective data in future feasibility evaluation systems.

    A Study on Urban Scale High-Resolution Sky View Factor Mapping and Applications

    Seung-Man AN | 2022, 113() | pp.57~74 | number of Cited : 0
    Abstract PDF
    A sky view factor (SVF) is a dimension-reduced urban canopy parameter (UCP) that captures three-dimensional urban surface morphologic form through a horizontal fraction. This study developed an urban scale high-resolution (2 m) sky view factor (SVF) raster mapping method and discussed it for further applications. The study site is Suwon administrative area, South Korea (121.04 km²), with a population of close to 1.3 million. In this study, airborne LiDAR-based three-dimensional point cloud (3DPC) data were used as an input to build urban scale high-resolution SVF raster maps. Two types of SVF maps (GB and GBH) are compared to describe the tree effect using Zonal statistics quantitatively. Results visually and statically explain a relationship between land-use-based urban surface form and the SVF difference map derived from two SVF raster (GB - GBH). The SVF difference average value explains the tree effect which mitigates micro-climate as a land cover lessens solar radiation on hot summer days. A further application research study about the high-resolution SVF map should follow to develop scientific knowledge and support climate-friendly urban planning.

    A Study on the Effect of the Living Space Environment on Life Satisfaction: Moderating the Effect of Traffic Accessibility

    You Donggyun , Jeong Hyun | 2022, 113() | pp.75~95 | number of Cited : 0
    Abstract PDF
    This study analyzed the effect of the living space environment on life satisfaction in the Seoul Metropolitan Area, and examined the moderating effect of traffic accessibility in the causal relationship between the dependent and independent variables. Life satisfaction was selected as the dependent variable of this study, seven aspects of the living space environment as the independent variables, and the indicators of traffic accessibility as the moderating variables. The independent variables of safety, environment, and economy had a positive effect on life satisfaction in Models 1 and 2. However, the independent variables of health and education had a negative effect on life satisfaction in Model 3, which added interaction variables, and traffic accessibility had a positive effect as a moderating effect on health and education. Accordingly, the negative causal relationship between the independent and the dependent variables was reduced. Therefore, this study has the following policy implications. First, it is important to improve the living space environment in order to increase life satisfaction. Second, urban planning that links the living space environment with traffic accessibility can increase life satisfaction.
