The main objective of study was to analyze the effectiveness of transit mall. To this end, this study compared operational status of transit malls in operation (Daegu, Seoul and Busan). For the city of Busan where the latest transit mall became operational in 2015, a discriminant model was proposed to determine user satisfaction/dissatisfaction. The outcomes of comparative study showed that each city has different operational focus - Seoul has focus on traffic demand management, Busan has focus on walking environment, and Daegu has focus on accessibility to public transportation. Also, the discriminant model indicated that market sentiment, convenience of bus service, traffic accident risk, number of pedestrian, market user number have effects on user satisfaction. These results implied that, to improve user satisfaction, measures for market revitalization such as opening events and forming consultative groups need to be prepared and traffic conditions should also be improved through expansion of curfew time, linkage with subway station.

The vehicles play a significant role in modern people's life as economy grows. The development of car navigation system(CNS) provides various convenience because it shows the driver where they are and how to get to the destination from the point of source. However, the existing map-based CNS does not consider any environments such as traffic congestion. Given the same starting point and destination, the system always provides the same route and the required time. This paper proposes a path planning method with traffic prediction by applying historical driving information to the Fuzzy theory and Bayesian update. Fuzzy theory classifies the historical driving information into groups of leaving time and speed rate, and the traffic condition of each time zone is calculated by Bayesian update. An ellipse area including starting and destination points is restricted in order to reduce the calculation time. The accuracy and practicality of the proposed scheme are verified by several experiments and comparisons with real navigation.

The indicators of an advanced society include the overall level of life quality and satisfaction among all the members. The overall life quality has close relationships with accessibility to urban space for the social weak. Access to facilities of interest and right of mobility in urban space are very important issues to the weak class in terms of transportation including the visually handicapped. In particular, great significance is endowed upon transfer facilities, which play mediating roles between facilities like passenger facilities, and the convenience facilities inside for the disabled, which are usually the only means for the disabled to access each facility. As they are provided to the visually handicapped as well, it's very important to analyze the concerned spatial distribution and offer the results. The previous studies on the subject, however, merely covered the perceptions of the users and the related statistical analysis. This study set out to analyze non-barrier space to promote the utilization of convenience facilities at passenger facilities by the visually handicapped and to secure their right of mobility by using a GIS for spatial analysis based on spatial data. The results show that it's urgent to supplement the existing space for the handicapped and that it's necessary to expand convenience facilities for the disabled such as paths with Braille points on them to promote their use of diverse convenience facilities inside.

Vehicles experience changes in driving behavior due to the various facilities on the freeway. These sections may cause repetitive traffic congestion when the traffic volume increases, so safety issues may be raised. Therefore, the purpose of this study is to perform microscopic traffic analysis on these sections using drone images and to identify the causes of traffic problems. In the case of drone image, since trajectory data of individual vehicles can be obtained, empirical analysis of driving behavior is possible. The analysis section of this study was selected as the weaving section of Pangyo IC and the sag section of Seohae Bridge. First, the trajectory data was extracted through the drone image. And the microscopic traffic analysis performed on the speed, density, acceleration, and lane change through cell-unit analysis using Generalized definition method. This analysis results can be used as a basic study to identify the cause of the problem section in the freeway. Through this, we aim to improve the efficiency and convenience of traffic analysis.

The government has implemented operating the bus information terminal (hereinafter, 'BIT') to use by building it at a major bus station to solve the problem of traffic congestion. Busan Metropolitan City has been continuously expanding the installation of 'BIT' since 2003. However, there are few research on the factor to use and satisfaction survey on 'BIT' from the perspective of the users. This study, in an effort to inquire into the 'BIT' utilization factor and its vitalization plan, conducted a face to face survey of 172 citizens who had the experience in the 'BIT'. The result of the data analysis showed that usability, convenience, and availability were the critical factors for a BIT use. In addition, the general intention to use 'BIT' was found to be very high as much as 90.7%. The contributions of this study are as follows. The academic contributions is that it proved the relationship between usability, convenience and the intention to use suggested by the information technology acceptance model is supported even in case of 'BIT.' For the practitioners this study provides ground data for a local government to make a plan of a BIT extension.

This study tries to provide the basic information for the plan to improve the information gaps of the disabled persons. After examining the legislation of the facilities for the disabled persons and former studies, it proposes some suggestions for the standards of unique space in public library, convenience facilities and traffic line. It also analyzed present conditions of five public libraries in Daegu Metropolitan City already having separate rooms and facilities for the disabled persons. The result shows that arrangement of disabled person's space and general convenience facilities are insufficient. Some facilities for disabled persons seems to be equipped just to suffice the standards. Detailed legislation or guidelines concerning facilities for them should be developed as soon as possible.
