The purpose of this study was to found that the important design reform points for improvement of the public open space quality. For this purpose, surveyed the users of the public open space and the experts working for the public open space planning for the design elements of the public open spaces in terms of importance and satisfaction. The scope of the study was limited to Mapo-gu, Seoul and the buildings constructed since 1992 were sampled. the data collected were subject to Importance-Performance Analysis. As a result, 'waste boxes, vending machines and other amenities', 'characteristic floor and pedestrian environment', 'designs and their layout in harmony with the surrounding and landscape facilities', 'facilities checking and patrol for safety' and 'entire area of the public open space'. Based on the above findings, the following reform measures are put forwards for improvement of the public open space quality; First, the public open spaces should be equipped with sufficient amenities. Second, it is necessary to check the facilities regularly, while enhancing the safety through patrols. Third, it is essential to reflect user's needs in public open space planning, while applying the important design elements to the public facilities. Fourth, in order to create a comfortable pedestrian environment within the public open space, it is deemed necessary to divide the space into the passages for passers-by and the recesses for uses. Fifth, it is necessary to amend the Building Code to the effects that the radio of the landscaped area to the entire area can be readjusted together with the night lighting facilities. Sixth, it is desirable to give the weights to the important design elements for the public open spaces, so that the quality public open spaces can benefit from the incentives. In addition, regular maintenance and management should be ensured by policies.

South Korea is seeking for a solution to the problems of traffic congestion and environment: the increase of bicycle use. However many people feel that using a bicycle is inconvenient. Therefore, we developed bicycle level of service model from the user's perspective so that the existing bicycle roads can be evaluated and improved. The purpose of this paper is to develop a bicycle level of service (LOS) model by considering user's satisfaction and multiple factors that affect bicycle LOS. Bicycle LOS criteria is estimated by applying an ordered probit model, which is suitable for research relating to choice. In addition, we determine the bicycle LOS using three-level(A-C) LOS structure from the user position considering the satisfaction level that people can distinguish clearly. The results show that the bicycle LOS is largely determined by the bicycle road width. Other factors are involved as well, including bicycle road type, the number of access and egress point on the bicycle road corridor, pedestrian volume, and frequency of meetings.

This research was conducted to propose the basic direction of a smart city plan for the satisfaction of residents of Gangwon-do. Initially, the awareness of smart cities among the residents of Gangwon-do was as follows: The response "I have no idea" was 21.7% higher and "I do not know the details, but have heard of it" was 15.1% lower than the awareness among residents across the nation. Based on these results, it was confirmed that awareness was very low despite the government's smartification reinforcement policy. In addition, the residents of Gangwon-do expected that their time would be saved and their living convenience would increase but were worried that their privacy would be invaded and that the conflict between generations would intensify. Thus, it is necessary to develop a plan to enhance the awareness of smart cities, as well as a plan to enhance digital awareness. Second, based on the importance of and satisfaction with the urban problem response system examined among the residents of Gangwon-do, it seems necessary to prioritize improvements in public space control and administrative problem responses involving deteriorated parks/plazas, pedestrian environment, and administrative processing inefficiency and fairness. Additionally, the first prioritization priority of the residents of Gangwon-do was "health/welfare/medical service" (27.7%); the second and third highest priorities were "transportation service" (26.3%) and "environmental service" (19.0%), respectively. In particular, as "transportation service" was highly preferred in the Chuncheon and Wonju regions and "health/welfare/medical service" was highly preferred in the Gangneung, Sokcho, and other southern regions, it was confirmed that the level of urbanization is deeply associated with smart services.

Although walking is an important transport mode which should be promoted, realistic studies about walking is not sufficient. Especially, due to the transportation planning oriented toward automobile, there is not realistic analysis method for walking in the Highway Capacity Manual. Therefore, in this study the fuzzy approximate reasoning was employed to build a model for the analysis of walkways service level. For the input variable the noise level and brightness as well as the pedestrian flow rate were employed and the output variable was the walking satisfaction degree. The fuzzy models were constructed for daytime and nighttime separately. The forecastability analysis for the models were conducted using $R^2$, MAE and MSE. The values of them for the daytime model are 0.802, 0.729 and 0.735 respectively and the values for nighttime are 0.893, 0.878 and 0.860 respectively, so it can be said that the models explain the real situation well. As a result of this study, it can be concluded that the noise level has stronger effects to walking satisfaction then the brightness in night.

The purpose of this study is to evaluate the user's evaluation of the street environment for the Urban Regeneration New Deal project, which maintains its original urban context and improves the urban environment, as opposed to the full-demolition projects such as urban redevelopment or reconstruction. A questionary survey was conducted on residents for the general neighborhood type of Urban Regeneration New Deal projects in Daegu. An IPA(Importance-Performance Analysis) was conducted to compare the user's satisfaction with the street environments. The main results are as follows. First, the importance and satisfaction of street environments were different for each project. Second, the cleanliness of sidewalks showed high importance and satisfaction at all projects. Third, residents' satisfaction with signs and buildings was high, but their importance was low. Last, residents' satisfaction with parking and the segregation of pedestrian and vehicle was low, but their importance was high. It is necessary to build differentiated plans and programs to meet the needs of residents in the Urban Regeneration New Deal projects.

This study examines the factors contributing to waterfront satisfaction among different generations, utilizing a survey on the use and perception of waterfront areas by residents of apartment houses in Tokyo's coastal region. The variables used in this study are developed through a review of existing literature, focusing on factors related to waterfront usage. Specifically, we select the proximity to the waterfront, duration of stay at the waterfront, and frequency of visits to the waterfront as key variables for investigation. In addition, the study further incorporates aspects related to waterfront recognition, such as the space, user behavior, and management status of the waterfront. Utilizing these variables, we carry out a correlation analysis to investigate the association between generational use and perception of the waterfront and their satisfaction with water-related experiences. The results identify three key factors to enhance waterfront satisfaction: First, to increase visits from both younger and older generations, improving pedestrian access to the waterfront is essential. Second, for middle-aged and older generations, creating waterfront areas closer to their residences can reduce travel distance and time, encouraging more frequent use. Third, maintaining clean and well-kept waterfront spaces is fundamental for all generations to enjoy relaxing experiences, thereby improving overall satisfaction.

The layout of facilities, in relation to information and navigational displays, has great influence on subway satisfaction, and tend to vary depending on the types of subway platform and transit station. However, until now, few studies have covered such aspects as of yet. Starting from this viewpoint, the purpose of this study was to use an IPA analysis technique to analyze that satisfaction on the importance of facilities to aid in accessibility, such as elevators and escalators, transit amenities and information and navigational displays depending on the types of platform and transit station. To do so, we've classified 15 metropolitan stations according to types of platform and transit station and analyzed differences in user importance and satisfaction as well as improvements for platforms and transit stations of similar type. By the analysis results of this study, we've concluded that the proper selection and positioning of elevator and escalator facilities and information and navigational displays was important when designing the subway station according to platform type (separate platform) and or according to the transit station type (cross, L, T types) where pedestrian flow heavily intersected. We considered that such analysis results would be helpful in the design of new stations and the enhancement of existing stations pursuant to a new direction that minimizes user inconvenience, and that improvement items should be developed first according to the platform and transit station types, which would be helpful in enhancing the efficiency of the subway improvement cost.

This study analyzed the influence of the perception of physical environment on user satisfaction and park use when people use the park to improve their health. The study is focused on neighborhood parks in Suseong-gu, Daegu city. Statistical analyses were employed to data collected from 143 visitors on site. First of all, in the perception evaluation of the physical environment of the park, accessibility and pedestrian environment are the highest at 4.04, while water space and attractions in the park as the lowest parts are at 2.32 and 2.66. After conduct factor analysis to type 22 physical environmental awareness components, five main factors--Comfort, Availability, Amenity, Facilities convenience and Visuality--were classified. Then, satisfaction and influence on park use were analyzed. As a result, the factors affecting user satisfaction were comfort, availability, amenity and facility convenience. Among them, the category of amenity was the most influential factor at 0.315. The factors affecting the park use were availability and amenity. Availability factor had a higher influence at 0.396 than amenity at 0.293. Therefore, in order to improve satisfaction and park use for health improvement, it is necessary to secure sufficient green areas and create a pleasant environment. Also, it is necessary to improve the quality of walkability from homes to parks, trail improvement and other improvements.

The purpose of this study is to increase the usage of satisfaction of outdoor exercise equipment installed at parks when plans and designs are made for renovation or formation of parks. In order to do so, the study surveyed and analyzed the usage satisfaction of 150 men and women who use outdoor exercise equipment in neighborhood parks located in Dongtan New Town. There were four factors that affect the variables of usage satisfaction. They can be defined as the main facility factor, awning factor, maintenance factor, and additional facility factor. From the result regression analysis of the total satisfaction rate and the factors, the main facility factor was the most influential of the variables. This could indicate that the facility factor affects the satisfactory rate of outdoor exercise equipment. This research is done only with the examples of neighborhood parks, so it limits the possibility of analysis of seasonal use. It is necessary to conduct analysis research of parks which installed many outdoor exercise equipment, such as a vest-pocket park, children's garden, and pedestrian/urban/metropolitan neighborhood parks.

This study deals with characteristics and risk of a PM based on user survey result, road driving test and data analysis of PM accident. Text mining method is applied to extract PM accident data from Big Data, which are claim data of private insurance company. Road driving test and survey on safety, convenience, noise, overtake ability, steering ability, and climbing ability of PM are performed to evaluate user's safety and convenience considering domestic road condition. As the result of claim data analysis, annual average increase rate of PM accident is 47.4% and average compensation of personal mobility is higher than that of bicycle by maximum 1.5 times. 79.8% of PM accident is self-caused accident due to unskilled driving and age-specific diagnosis rate of driver over 60 is higher than that of under 60. Diagnosis rate of over 60 at lower limb, foot, rib and spine is especially higher than that of under 60. As the result of road driving test and user survey, satisfaction level on safety and convenience of PM is evaluated as close to that of bicycle and satisfaction level of PM is increased after boarding. Overtake ability, steering ability, and climbing ability of PM are evaluated as same or better than that of bicycle but warning equipment to pedestrian or bike such as horn is required because noise level of PM during driving is too low. Finally, user survey result shows that bicycle road is suitable for PM and safety standard, advance-education and insurance are required for PM. It is suggested that drivers' license for PM can be replaced by advance-education. Results of this study can be used to prepare safety measures and legal basis for PM operation.
