There are many efforts for expanding bikeway plans and increasing bike utilization. In this study the authors try to find the primary factors that affect bike users' satisfaction under limited budgets. As satisfaction is a qualitative variable, the authors developed a bike user satisfaction model by using structural equation methods. The bikeways are distinguished between bike lanes on public roads and exclusive bikeways along the Han River, as the characteristics and attributes should be different. The model shows bikeways on public road have a user satisfaction equal to 0.248*(safety)+0.405(accessibility). Bikeways along the Han River have a user satisfaction equal to 0.437*(accessibility)+0.405*(economic feasibility). In both types, accessibility affects satisfaction. Safety in more important to users on public roads, while economic feasibility affects those on the Han River bikeways.

In this study, in order to understand the needs for infrastructure services experienced by the public, we compared the level of infrastructure service satisfaction and analyzed the characteristics of infrastructure services by region. In this study, as a result of comparing the level of infrastructure satisfaction between regions, transportation and living infrastructure services were generally low. However, the characteristics of infrastructure services within the region are clearly different from the results of the infrastructure satisfaction between regions. Therefore, it is necessary to examine the level of infrastructure satisfaction within the overlooked region, and the satisfaction, improvement importance, respondent characteristics, and quantitative indicators need to be considered.

Purpose: The purpose of this study was to suggest new direction for domiciliary care for elders provided by public institutions in rural areas. Method: The participants in the study were elders using one of 11 public health care institutions, of which 8 operated day care services exclusively, and 3 operated both day care and short-term respite care services. A survey was conducted using a structured questionnaire that included items on general characteristics of the service users, conditions of the services, personnel, financial status, facilities, and perception of the tasks of the staff. Result: The service content of the day care centers included Western and Chinese medical service, physical services, activities of ADL, nursing care services, meal services and transportation services. Domiciliary care centers provided a wide variety of health and social welfare service for elders. Personnel consisted of 3 to 8 staff for day care centers and 7 to 10 for domiciliary care centers. Both types of centers rely on financial support from local government for operation. The perception of the staff was the need for operation of these centers by public health facilities such as public health centers and sub-centers. Conclusion: The result suggest a need to activate the function of public institutions to provide domiciliary care for elders. For this new change, the role as a social support system must be developed.

Public spaces in the cities are social and economic resources to maintain sustainable urban revitalization. As an importance of public spaces is getting increased, many cities focus on public space management and introduce their own management system. NYC Plaza Program is one of the public space management systems in USA and it was designed in order to transform underused roads and streets into pedestrian public spaces throughout the New York City. Plaza management system works with private organizations' participation as NYC Department of Transportation empowers selected private organizations to the right of management and assists their efforts. In this study, we focused on how the plazas are managed by private sectors and seek to find out characteristics of types of management methods based on landuse(residential, commercial and openspace) status around plazas. We analyzed 61 plazas that generated by NYC Plaza Program with three major conditions of management system including organization, fund and activities. There are three major findings from the analysis. 1)In most residential surrounded plazas, resident-initiative organizations manage small scaled fund and activities meanwhile public agencies support their management. 2)BID is a dominant tool in the commercial surrounded plazas. BID provides with secured fund, mid-sized activities and a broad network with commercial facilities. 3)Openspace-surrounded types are usually using supports of exiting organizations and fund system.

Seoul public bike program facilitates access to bicycles and offers potential for greater mobility and health for users. Furthermore, it would have positive impacts on transport congestion, energy use, and the environment. Hence, it is important to find future rental locations by taking to account both bike-demand and regional imbalance. This paper first finds eligible candidates of rental locations with the required spatial conditions such as a sufficient sidewalk width and accessibility of bike pick-up vehicles. And then, estimates public bike daily usage for each selected location via random forest based on Seoul public bike historical usage, Seoul geographical features, regional characteristics, and populations. This study contributes to a better comprehension of the Seoul public bike program, and would be useful in determining new public bike rental locations.

In this study, factor and cluster analysis are used to classify characteristics of the administrative basic unit, "Dong", of the Incheon Metropolitan City. Travel characteristics of the classified groups are then analyzed through databases to provide directions of urban transportation planning. First, industrially developed administrative-dong show a high commuting volume by using cars. Thus the analysis indicated the need to staggering work-hour system and signal operating system policy. Second, commercially developed administrative-dong show heavy use of public transportation and long distance commute as well as high volume of shoppers. The analysis indicated the need to improve road infrastructure. Third, densely populated administrative-dong show a high rate of commute to work and school as well as long hours of commuting. Thus the analysis indicated the need to improve road transportation policies during rush hours. Fourth, administrative-dong with multiple characteristics feature heavy pedestrian traffic thus the study analyzed the need to improve pedestrian environment policies. Lastly, administrative-dong in close proximity to train stations feature extensive use of biking as well as high volume of shoppers and students commuting. Thus the study analyzed the necessity to have plans to enhance accessibility.

In this study, various usage patterns were analyzed after establishing a data mart for micro mobility analysis based on the rental history of public bicycles in Seoul. Rental history data is origin-destination data that includes the rental location and time, and the return location and time. About 1500 rental locations were classified according to the characteristics of the location to create a 'station type' dimension. We also created a 'path type' dimension that displays whether the rental location and return location are the same. In addition, a derived variable called speed, which is obtained by dividing the distance used by the time used, is added, and through this, the characteristics of the riding area and the reason for the rental can be estimated. Meanwhile, administrative district link, administrative neighborhood link, and station type link were created to apply network analysis. Through this analysis, the roles and proportions of administrative districts, public facilities, and private facilities engaged in micro-mobility services were visualized. 49.9% of rentals occur at rental offices near transportation facilities, and half of them occur at rental offices near subway stations. The number of rentals during the evening rush hour is more than double that of the morning rush hour. When the path type is unidirectional, there is a fixed destination, so the distance and time used are short, and the movement speed tends to be high. In the case of round-trip, the purpose of use is exercise or leisure, so the distance and time used are long, and the movement speed is slow. It is expected that the results of the analysis can be used as reference materials for selecting new rental locations, providing convenient services for users, and developing user-specialized products.

Public libraries should plan and provide services that satisfy various needs of the local community users. In order to understand library users, it is essential first to grasp the service areas of libraries. The current service areas of public libraries are primarily set based on administrative boundaries of the areas where the libraries are located, which limits the consideration of actual user access patterns to the libraries. In this study, we aim to create service areas that incorporate the transportation and geographical characteristics of the library's surroundings and reflect the access patterns of library users. Specifically, we utilized street network data from 502 libraries in 7 metropolitan cities to determine the travel distance and time from user locations, considering gradients, to the libraries. Subsequently, we applied the shortest path algorithm to generate service areas within a 30-minute walking or driving range. As a result, we confirmed that there are differences in the service area patterns of libraries depending on topographical factors, and this better reflects the realistic conditions of library access compared to service areas based on straight-line distances. This method of generating service areas contributes to a more accurate understanding of library users' numbers, characteristics, and needs.

In regard to the growth and development of Innocity from improvements in Innocity settlement environment, this research examines the level of satisfaction of Innocity settlement environment to propose a political implications. We deduced the main cause of settlement environment satisfaction by performing logistic regression on the public institution employees level of satisfaction in respect to 4 Innocity characteristics?six physical properties, three social properties, five facility properties, three economical properties?and three general questions. As a result, the greatest factor of settlement environment was physical properties, such as natural environment and scenery, residential environment, availability of diverse uses in the surrounding area, and access to public transportation. In addition, social characteristics (relationships with neighbors), and facilities (availability of industrial, research and educational facilities) were also significant. This research provided political implications for future Innocity settlement environment improvements despite limiting factors such as residents' perception and limited surveyed sites.

With the increase in the population of our cities and the rapid increase in the number of private cars, urban traffic has become more and more congested. At this stage, urban public transportation has become one of the main ways to improve urban traffic congestion. Aiming at the problem of how to improve the basic capacity of buses in multi-line transfer stations, this paper conducts simulation research based on anylogic software. Through micro-simulation analysis of vehicles entering, stopping, and exiting the station, combined with the delay model theory, the vehicle is given Stop organization optimization and station layout improvement methods, so that vehicles can run in the station more stably, smoothly and safely. Case analysis shows that applying this method to the roadside parking problem, the main and auxiliary bus stations have a significant improvement in operating capacity compared with the conventional tandem double bus stations, and the service level of the main and auxiliary bus stations has been significantly improved.
