This study analyzed that the impact of the bus use environment on users' stress in each step of bus use, from accessing to leaving to transfer, in the city of Daejeon. For this, we collected the stress data from 300 users using personal interviews at the bus stops and on-board bus. Also, we used factor analysis and structural equation model method for analysis of the impact of external and internal bus environments on stress of users. The results of this study showed that the highest stress impact factor was an onboard factor(${\beta}=.416$) including 'density and crowding', 'no seat to seat' and 'low ride comfort and safe'. The next stress impact factor was transfer factor including 'insufficient transfer information', 'lack of connectivity of bus and subway' and 'uncomfort transfer route'. From the above, we recommend that bus policies need to focus on not the supplier but users and also, this user based policy need to be more specified considering the characteristics of various users such as females, the elderly, irregular users, and so on.

Recently a number of car sharing studies have been conducted that share vehicles from a consumer perspective. Meanwhile, Japan's MLIT had empirically implemented social experiment and policy for the installation of sharing car in order to make better use of the business forms and rapidly increasing car sharing associated with express bus as a new type of transaction from a sharing economy perspective. Therefore, this study examined the case of connecting with the express bus in Japan and analyzed and discussed the contents at the practical level. In addition, data collected for 229 car sharing users were verified empirically. The multiple liner regression analysis showed that three types of perceived values effect on the usage intention in the order of economic value, time value and psychology value. These findings suggest that car sharing users' perceived values are very important for increasing the degree of satisfaction with usage intention.

In the modern society, people can easily reach destination by using the rapidly developed public transportation services. Recently, location information is provided through the network, but this is useless to the weak people on transportation like the handicapped. This paper proposes a bus alert terminal system equipped with the arrival information of public buses based on location information and distance measurement sensor. By using this system, we look forward to providing more convenient and accessible services for the weak people on transportation.

The main objective of study was to determine the optimum level of bus service by bus route types for the effective improvement of bus route operating in semi-public transportation management. In pursuing the above, this study proposed to classify by bus route types based on publicity, profitability and potentiality. Using this methods of the classification, 113 bus routes in Busan were classified into bus routes of 8 types. And this study proposed desirable management of bus route operation according to 8 bus route types considering 9 bus operating characteristics such as bus route distance, operating number, state of passing through the CBD and so on. For proposing the desirable management, it was to do a statistical analysis of PCA(Principal Components Analysis) and to abbreviate 9 variables to 3. And it was drawn a conclusion effectively by making comparison between 8 bus rout types and 3 bus operating characteristics.

As one of the most traffic devices, bus has played a great role in Korea for the last years. However, a great many peoples in big cities have continually decreased with the increase of private car ownership. It causes lower quality of bus service and unstability of operation in many bus companies. In the several local government, the operation system of bus was changed to Bus Quasi-Public Operating System. The aim of this study is to assess the effects and to suggest improvement strategies of Bus QPOS. According to the results of the analysis, Bus QPOS has brought various positive effects, but it has occurred negative effects, especially a much increase of government subsidies to bus company. To resolve a negative effects, government should examine the whole condition of bus operations. This study suggests strategies to improve Bus QPOS, which is including transparency of management, fair assessment system, standard cost system for bus operations.

The purpose of this study is to present an analysis and implications for the metaverse-based virtual real estate transaction service. Through blockchain-based technology and metaverse, the world we live in is expanding naturally. Therefore, changes in the environment and perceptions of market participants are also very important factors. The concept and thinking about the existing asset value change and investment are also changing. This means that you can generate profits through value and investment in intangible assets. The service user aspect is a case of investing in the future value of virtual real estate that if more users participate rather than the present value, the principle of supply and demand will be applied to increase the number of consumers and the price will naturally rise according to the principle of scarcity. The service provider provides a technical platform for the service to directly transact the portion of the virtual area considered of interest directly through the virtual real estate purchase business. As the number of participants increases as well as funds and transaction fees, various revenue models such as advertisements can be discovered and provided. It plays the role of providing jobs and information through new services. As a stakeholder, governments can exploit the emergence of new technologies and products to create people and services and secure economic benefits. Of course, various institutional supports should be provided so that new services can settle in the market while mitigating risk factors. This study is meaningful in that it contributes to the establishment of a domestic metaverse-based environment and related research and is utilized in the study of virtual space real estate services.

BIS is an arrival guidance system which is able to supply passengers with bus service condition via Kiosks at a bus stop, internet and mobile service through pinpointing bus location in real time. It is very significant to improve the quality of traffic information by quality control of GIS-based bus network so as to maintain navigational information and to implement reliable BIS. Therefore this study aims to build criteria to quantitatively evaluate data quality of the product in accordance with the process in bus network data and to suggest guideline of quality control. To achieve this, we have categorized geometric and logical errors occurring during constructing bus network database by giving a specific case study on TAGO and set up sectional guideline and procedures to examine database for systematic and coherent quality control management. Proceeding from what has been said above, the outcome of our research leads to quality guarantee for objective and reliable bus network database and is fully expected to bring benefit of providing a more accurate public transportation information and improving reliability of BIS through preventing a variety of errors in system operation in advance.

Amid the explosive growth of various metaverse platforms, there is no unified indicator to measure, analyze, and evaluate based on customer experience. Therefore, the usability evaluation factors in metaverse were identified through a heuristic methodology and literature review, to evaluate the metaverse, a two-to three-dimensional virtual world platform. A measurable system was established by subdividing 20 items in 5 fields, including user control, information structure, design and content, and usage environment, derived through Delphi technique. Based on this, after experiencing the actual contents of major metaverse platforms such as Roblox and Zepeto, usability was evaluated and comparative verification was conducted. As a result, it was estimated that metaverse user experience could be improved as its utility was derived relatively high in terms of user control and content. This study constitutes a theoretical contribution by extending the usability evaluation system, which has been widely used in the field of service design, to the fields of extended reality and mixed reality. At the same time, it has practical key findings of providing basic judgment standards to stakeholders in the metaverse field, as well as policy implications for digital capability enhancement and industry revitalization.

The influence of bus stops near signalized intersections is one of the important factors which cannot be negligible in the analysis of the capacity of signalized intersections. Absence of consideration of bus bay can reduce capacity and increase the time that the stop of buses block other traveling vehicles. This influence is reflected by the bus blockage adjustment factor in KHCM, but the factor does not consider the course of each bus passing the intersection. Particularly, left turn buses have more influence on the capacity than the other buses and require the minimum length of the road for lane changes. All the existing criteria can apply only to arterial roads on which mostly traffic flows are continuous. And the criteria. which can determine the optimum location and the minimum distance between a signalized intersection and a bus bay, is not prepared and the related study is insufficient. Therefore, a theoretical formula is derived in this study being based on the theories which are avaliable to apply to the situation of signalized intersections.
