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.

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.

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.
