The issue of spatial equity in public healthcare services is an important issue in rural areas with lower healthcare resources. This study investigates spatial accessibility to public healthcare services by public transport, focusing on bus travel in Yeoju-gun, Gyeonggi-do. We comprehensively analyzed the spatial patterns of accessibility using the measures based on spatial interaction, and compared them with the accessibility patterns by car travel. As a result of analysis, the spatial disparity between the central part of Yeoju-gun (lower accessibility) and its peripheries (higher accessibility) was identified. More specifically, the area and population of lower accessibility areas are greater than those of higher accessibility areas, and the difference in the accessibility values between higher and lower accessible areas is considerably large. Moreover, the accessibility patterns appears somewhat different according to two different travel modes. In particular, about 20% of the entire area presented the opposite patterns between two travel modes. Interestingly, less populated peripheral areas are more included in higher accessible areas by car.

The railroad freight transport has great merits that can transport mass and specific items(dangerous goods), but it takes a long time because of low accessibility to the logistics facility and the complex process of loading freight in middle station. This paper analyzed volumes and characters of each railroad freight item, and was carried out the effect of applying E&S system to Gyeongbu line containers to find the method of reducing transport time and effective container transportation. As a result of Cost-Effectiveness analysis, the block train(B/T) is reducing transport time more about 1~2 hours. The road congestion cost is saving about 2.2 billion won. And due to skipping work of organizing train, personnel and equipment expenses savings expected about 9 billion won. It is expected that the E&S system enhances the container transport service and has an effect positive influence on making a efficient method of transport. But It is necessary to estimate pre-feasibility of applying E&S system that the standard of estimating cost and benefit is required further examination.

This paper developed social equity indicators for evaluation of bus networks. This paper divided the social equity is into 4 categories such as horizontal equity, horizontal accessibility, vertical equity, and vertical accessibility and social equity was defined as integrated concept of these individual indicators. A simulation was performed by using the newly developed indicators to the toy network. On the basis of the simulation result, the social equity indicators are significant to the relative comparison for each zone. And, it was proved that optimal bus network alternative could be different depending on inclusion of the social equity indicators. Thus, it enabled to evaluate the bus network, as a public resource, considering not only the economic efficiency but also social equity. This paper suggested evaluation method for bus network considering social equity using indicators newly developed.

This paper aims to analysize the regional disparity of rural life service. In other words, analyzing the spatial distribution of the single-households elderly and service accessibility to public transportation, and the relationship between them in rural. The results of this study are as follows. First, there is a high concentration of the single-households elderly in Gyeongsangbuk-do and Jeollanam-do, and the distribution of them shows a tendency to cluster locally. Second, the vulnerability area of public transportation are concentrated on the myeon area. Third, The above-average proportion of vulnerable single-households elderly in Gyeongsangbuk-do and Jeollanam-do are concentrated on the myeon area. This result show that there is a positive correlation and high values are concentrated. This paper is expected to contribute to the regional development projects and effective implementation of rural polices.

This research aims to examine the influence of road transportation infrastructure on the mobility of goods transport and the regional economy in Langkat Regency in Indonesia. This type of research is an associative and explanatory research whose data is obtained through a questionnaire survey. This study took a sample of 305 respondents using probability sampling in Langkat Regency, North Sumatera, Indonesia. Data analysis techniques use path analysis. The research results showed that the road transportation infrastructure variables had a significant and positive effect on the mobility of goods transport. Road transportation infrastructure and freight mobility simultaneously have a significant and positive effect on the economy of Langkat Regency. Road transportation infrastructure with the dimensions of road accessibility and maintenance partially directly has a significant and positive effect on the economy of the Langkat Regency. Road transportation infrastructure with the dimensions of road design and road construction quality partially does not have a direct effect on the regional economy, but has a positive and significant effect through the mobility of freight transport. The mobility of goods transport becomes an intervening variable that acts to mediate or determine the relationship between road transportation infrastructure variables to the regional economy.

Background: This study was purposed to analyze the effect of spatial accessibility to the psychiatry department in general hospital on the outpatient visit of mental patients. Methods: Data was provided from the Statistics Korea and Statistical Geographic Information Service, National Health Insurance Service, Health Insurance Review and Assessment Service, and Korea Transport Institute in 2015. The study regions were 103 administrative regions such as Si and Gu. The 103 regions had at least one general hospitals with a psychiatry department. The number of outpatient visit of mental patients in regions was used as the dependent variable. Spatial accessibility to mental general hospital was used as the independent variable. Control variables included such as demographic, economic, and health medical factors. This study used network analysis and multi-variate regression analysis. Network analysis by ArcGIS ver. 10.0 (ESRI, Redlands, CA, USA) was used to evaluate the average travel time and travel distance in Korea. Multi-variate regression analysis was conducted by SAS ver. 9.4 (SAS Institute Inc., Cary, NC, USA). Results: Travel distance and time had significant effects on the number of outpatient visits in mental patients in general hospital. Average travel time and travel distance had negative effects on the number of visits. Variables such as (number of total population, percentage of aged population over 65, and number of mental general hospital) had significant effects on the number of visit in mental patients. Conclusion: Health policy makers will need to consider the spatial accessibility to the mental healthcare organization in conducting regional health planning.

This study is aimed at identifying the relationship of transit accessibility types to its related travel frequency in the Seoul metropolitan area. A multi-level poisson regression model is employed after categorizing transit accessibility into 18 types based on locations of residential and work workplace. Analysis results offer three policy implications in improving transit use in the Seoul metropolitan area. First, increase in transit ridership can be more effectively attained when policies concerning both competitive and complementary relationships between bus and rail transit are incorporated. Second, transfer system needs to be focused on such two modal perspectives as one travels from Seoul to suburban area and residential areas given the fact that walking accessibility to bus transit is good but that to rail transit is poor. Third, it is more effective to emphasize rail transit priority rather than bus transit, especially for the travel from suburban area to the city of Seoul in order to increase transit ridership.

Walking behaviors are one of the most basic transport modes in daily life. As a result, the efforts and concerns on pedestrians are consistently increased. This study tried to reveal significant factors for pedestrian volumes through structural equation models and compare the impacts of the whole time of day, off-peak time, peak time on the pedestrian volumes. The results of the analysis show that commercial business factors, accessibility factors, walking environment factors are the most significant factors that increase pedestrian volumes. Whereas, housing factors do not contribute to increase the pedestrian volumes. In the non-peak time, the weight of commercial business factors is higher than the whole time of day, while the weight housing factors, accessibility factors, walking environment factors are lower. In the peak time, however, the weight of commercial business factors decreases rather than the whole time of day, while the weight of the other factors increase.

This study analyzes the accessibility patterns for commuting trips in Seoul Metropolitan Area using National Census Data between 1990 and 2000. the results show that the accessibility increased between 1990 and 1995, while it decreased between 1995 and 2000, due to the raised commuting time. Seoul, Kangju, Yeuju, Yangpyoung, Gapyoung show relatively high accessibility. The GINI parameters tell that the regional balance for commuting accessibility were worsen between 1990 and 1995, compared to that between 1995 and 2000. The accessibility patterns for commuting to Seoul were also analyzed and the result shows that the accessibility reduced between 1995 and 2000. Kwachun, Kwangju, Sungnum are found to have very high accessibility to Seoul, which is close to Soeoul with high percentage of incoming commuting trips. These results indicate that even continuous transport infrastructure supplies were not enough to solve the congestion problems for commuting trips in Seoul Metropolitan Area because of the induced traffic and traffic congestion.

The ratio of the mobility handicapped person is about 25.8% of the total population in Korea(MCT, 2006). In order to prepare for the enforcement of the "Transportation Services Improvement Act for the Mobility Handicapped People"(MCT, 2006), various equipments and installations should be developed to ensure appropriate safety level for the mobility handicapped persons in maritime transportation. While approximately 10 million people are using domestic passenger vessels annually, preferences for maritime transport is very low, especially for the mobility handicapped. This study reviewed a current status of the mobility handicapped person in domestic passenger ship and analysed the improvement plan for them. To investigate the current status of domestic passenger vessel usage by the mobility handicapped, to analysis the requirements for amenities necessary for the mobility handicapped and select the ones to be developed based on the investigated results and to do feasibility study of barrier-free ship.
