지역 접근성 측정을 위한 일반모형 = A Generalized Measurement of Regional Accessibility

다국어 초록 (Multilingual Abstract)

The concept of accessibility is related to the concepts of nearness, proximity, ease of spatial interactions, potential of opportunities of interactions, and potential of contacts with activities or supplies. Therefore, accessibility characterizes the inherent advantage of a place with regard to overcoming spatial friction and serves as a main fctor in generating land values, affecting ultimately the land use. Accessibility is one of the most useful concepts for the study of spatial structure mainly due to the fact that it has a single value at each location, if it can be properly calibrated. The concept of accessibility is associated with appreciation of the type and quality of the transportation system as well as of the availability of satisfactory potential destinations with respect to a given need (e.g. looking for an employment place, shopping, leisure, etc.), which can be reached from a location through the use of a particular transportation system. Therefore, accessibility should be calculated for each type of the transportation system, since the characteristics of each system in general vary significantly from system to system. Various numerical indicators of the accessibility have been suggested in theoretical analysis and used in empirical investigation and planning. Since travelling behavior shows quite diverse patterns in accordance with the transport system, which makes it necessary to identify the characteristics of a particular transport system in accessibility measurement modelling. The configurations of such characteristics may be behavioral responses of people to the particular transport system as well as attributes of the transport system such as the route distance, mode of transport, travel time, cost supply capacity, assortment, price, quality operation hours, congestion, queuing time, and location in relation to other activities or supplies.
However, there exists conceptual ambiguity as well as a rather large gap between the numerical indicators in current use. Still transportation planning appears to suffer from a shortage of models which are capable of calibrating accessibility of a region in a generalized model. The purpose of this study is to develop a generalized measurement scheme for accessibility. We suggest population potential model as a generalized measurement of regional accessibility. We attempt to redefined the potential model in appropriate manners.
