There have been a few researches related to the changes and characteristics of commuting networks among urban cities in the Korean Capital Region through specifically investigating cities' functional connection patterns. In that, until now, most of studies had pointed the Seoul-centered spatial interdependency in the region, the study is expected to draw policy implications on future metropolitan growth management by analyzing the changing patterns of spatial interdependency among other cities as well as between Seoul and those cities. We conducted analyses on the temporal pattern of spatially connecting networks among the metropolitan cities(Seoul, Incheon, and Gyeonggi-do's 31 cities and counties) by using JDR(Job Dependency Ratio Index), JOR(Job Occupancy Ratio Index), and Ⅵ(Volume Index) for the O/D matrixes of attending and commuting population from 1990 to 2005. The study identified three characteristics on changing spatial interdependency among cities in the region. First, the scale of the Seoul metropolitan area has expanded in the region, even if the centripetal force of the Seoul city to other cities has decreased since 1990. Second, other cities has increasingly played an influential role in the region because of close functional connection among cities as well as increase in the number of central cities forming a small-size metro area. Third, there are prominent central cities of small-size metro areas while their number and spatial scope has increased since. the central cities includes traditional independent cities in the early 1990s, such cities covering new towns as Koyang in the late 1990s, and newly growing cities such as Yongin and Icheon in the early 2000s.

This research is not only to investigate impacts of the type and location of both shopping and leisure facilities on travel mode choice. But the research is also to identify variables differently influencing travel mode choice by travel purpose. For them, the research uses multinomial logit models with the data surveyed in the seoul city in 2007. The findings resulting from these analyses suggest three policy implications for shopping and leisure travels. First, travellers tends to take more non-automobile modes for their travel purposes when parking is more difficult in either their origination or destination, while residents takes more public transit when its accessibility is more convenient in their origination than destination. Additionally, comparing the impact powers on travel mode choice between parking availability and transit accessibility, the former is more important than the latter in order to decrease the automobile dependence. Second, people tends to walk to get to a Big Discount Mart as much as they drive, while they drive much more their own cars for it, compared to the modes of public transit. It implies that people drive less their cars for it when the facility is located near their residence. Finally, travellers tend to take bus as almost same as drive their own cars to attain their purposes when they reside in the areas where rail transit accessibility is poor unlike central and sub-central business districts in Seoul. It gives us an implication that bus should be competitive to car in the areas.

This study has been aimed to identify the effects of compact-city development at the living area of neighborhood level on transportation policy measures in the capital region. For the purpose of it, the study established the regression analysis model of compact-city planning elements to modal split and inner-travel ratio. The planning elements are defined as Density, Diversity, Design and Accessibility. The analysis results demonstrate that compact-city planning should be applied to the capital region at the neighborhood level to reduce car-oriented travel pattern. In addition to it, the results suggest that policy measures of both modal split and self-sufficiency might not be simultaneously accomplished by compact-city planning. For example, both population density and rail accessibility have a positive impact on reducing car split while they have a negative impact on self-sufficiency and inner-travel ratio. It means that compact-city planning at the neighborhood level need to be applied to achieve either of them, not both.

This study is aimed at identifying the association of commuting behavior with obesity for workers in the Korea Capital Region. The study surveyed total 1,285 commuters whose their major affairs are deskwork-oriented so that we obtained their obesity status on Body Mass Index as well as their commuting behavior. The measures of the latter was comprised of a main commuting mode, in-vehicle time, out-vehicle time, transit transfer in order to identify the amount of physical activity obtained through commuting behavior. In order to analysis the causal relationship between commuting and obesity, this study designed the structural equation model, path analysis and the program was amos 7.0. The results indicate prominent causality. Especially out-vehicle time influence on reducing their BMI, and the other way in-vehicle time influence on increasing their BMI.

This study is not only aimed to determine priorities of area-wide transportation policies in the five metropolitan areas through analytic hierarchy process(AHP) methodology. But it also attains to demonstrate that area-wide policy items could be differentiated by each metropolitan area. For it, the study surveyed almost 200 transportation experts for a questionnaire with 7-point pariwise comparison tables of policy items with three levels which were drawn out by 7 experts through brainstorming. The analysis results, in general, demonstrate that area-wide transportation policies need to be more focused on expanding transit-oriented facilities as well as enforcing travel demand management policy, especially, through the strong land-use and transportation coordination. In addition to it, they also suggest that area-wide transportation policy should be differentiated with consideration of the characteristics and transportation conditions facing in each metropolitan area. On the other hand, the study proposes that the AHP methodology could be a useful analysis method to derive priority items of diverse metropolitan transportation policies.

This research aims at analyzing the actual effect of transit oriented developments (TOD), and finding implications from the analysis in order to establish an appropriate way for the implementation of TOD, which has been emerging as a new paradigm for urban development. To this end, this research classified the planning elements into two categories according to characteristics of public transit supply and land use. This research effort selected developments of rail station areas in Seoul, Korea as a test-bed because many of rail station areas have already been developed on the basis of the concept of TOD. In addition, the author could utilize the data from Seoul bus-cards, which are used in Seoul Metropolitan area for riding buses and subways, in order to investigate the characteristics of transportation demands, which was included as a dependent variable in this research. This research established an effect analysis model using a structural equation modeling in order to comprehensively consider the variables for the diverse planning elements for TOD introduction in a realistic manner. In the structural equation modeling, this research set up an effect analysis model between the planning elements through dividing and integrating potential variables. The result of model calibration indicated that all statistics reside within significant level, the signs of factor loadings turned out reasonable. Based on results from the statistical analysis, this research effort found significant results by each planning element.
