접든성통제는 고속도로에 있어서 교통사고 감소의 가장 효과적인 수단들 중의 하나로 인식되어져왔다. 이러한 접근통제의 새로운 적용으로서 접근성관리는 과도한 투자 없이 일반도로상에서 교통사고를 감소시키는데 활용되고 있다. 이 연구의 목적은 도시간선도로상에 있어서 접근성관리와 교통사고와의 관계를 교통사고비용의 측면에서 분석하는 것이다. 이를 위해, 이 연구는 미국 텍사스주 대도시 지역내 중앙분리간선도로의 교통사고자료를 다중회귀모형을 이용하여 분석하였다. 이 연구는 자료분석의 결과 다음과 같은 사실을 발견할 수 있었다. 첫째, 접근성관리는 도시간선도로의 교통사고비용과 밀접한 관계를 가지고 있었다. 둘째, 이러한 접근성관리와 교통사고비용과의 관계는 도로의 교통상황과 도로변 토지이용상태에 따라 다양하게 나타났다. 셋째, 대체로 접근성관리와 관련된 요인이 교통상황 및 토지이용상태에 관련된 요인보다 더 교통사고비용과 밀접한 관계를 보였다. 마지막으로, 교통사고비용을 설명하는데 있어 가장 중용한 접근성 관리 요인은 외부접근로의 간격으로 나타났다.

Public transportation accessibility has been evaluated through minimum level of service for public transportation. However it is evaluated based operators rather than users. This study analyzed the users' accessibility(first-mile, last-mile) to public transportation using altteul transport card data. As a result of user's accessibility of public transportation, rural areas was lower than that in the urban areas. This study calssified type 1 and 2 based average approach time, and average approach time of Type 1 and 2 were more than average approach time of total area. We propsed an efficient introduction of autonomous public transportation on-demand service using delphi survey. As a result of delphi survey, experts agreed on 9 items regarding function, service item, route operation, approach distance, route mileage, punctuality.

수도권의 도시화 과정은 서울로의 교통 접근성의 변화에 따라 급속하게 확산되었고, 현재도 진행 중이다. 도시화 과정 속에 인구 교외화, 주택 수의 증가, 도심용지 토지이용 증대, 토지가격의 증가 등의 다양한 공간적 변화가 이루어지고 있다. 이러한 급속한 도시화의 과정 속에 국토의 난개발이 이루어졌고 자연생태 파괴, 주택부족 및 교통 문제, 토지 투기 등의 사회적 문제를 야기했다. 본 연구에서는 도시화 현황을 살펴보고 교통접근성의 변화에 따른 주변 토지이용 변화의 상관성을 분석하였다 상관성 분석 결과를 토대로 멀티 에이전트 시스템(MAS)을 이용하여 교통접근성과 토지이용 에이전트 간 상호작용의 관점에서 시뮬레이션 하였다. 그래서 교통접근성의 변화로 인한 주변 토지 이용 변화를 공간적으로 예측하려고 한다. 도시화 현황을 살펴보기 위해서 지적도 자료를 이용하여 미시적인 경관 분석을 실시한 후 교통접근성의 변화에 따른 주변 토지이용 변화의 상관성을 분석하기 위해 교통자료와 토지이용 자료를 GIS분석 및 통계 분석하였다. 그리고 상관성 분석 결과를 멀티 에이전트 시스템 전용 플랫폼에 적용하여 시뮬레이션 분석을 하였다.

Various urban transport policies have an effect on urban transit riderships and accessibility. This study reports variations of metropolitan subway travel patterns affected by an enormous change in bus routes and transfer discount fare policy between subway and bus mode conducted by Seoul city in July 1st of 2004. In an effort to see the difference between the before and the after policies, two data sets are prepared. Firstly, on a daily bassis. an origin-destination trip table of May of 2004 is used. Secondly, on a daily bassis, an origin-destination trip table of August-September of 2004 is used as a counter measure. Even if seasonal variation was not considered, Seoul metropolitan area have experienced increasing riderships and accessibility. Finally, the effects of accessibility in spatial interaction model by rall service changes such as random shocks were scrutinized and interpreted in detail.

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.

Accessibility is the generalized definition on how ease of access. Accessibility is used to appraise transportation project such as capturing the quality of the existing state of the transportation system at diverse spatial levels, It also reflects on the effect of improvements to the existing travel modes and the intoduction of new modes. The overall goal of this study is to propose a measure of urban accessibility in Seoul which can analyze various behavior of travelers in the city and to present applications. In this study, we apply measures of accessibility which are developed by CTR(The Center for Transportation Research, the University of Texas at Austin) to construct the urban accessibility index applicable for explaining trip behavior in Seoul. We evaluate sustainability of urban transport system in Seoul in 2002 by using the MAG(Modal Accessibility GaP) index which is developed to measure the accessibility gap between the more energy-efficient mode and less energy-efficient mode of transport. By analyzing the change of MAG index between 2002 and 2004 based on network data, we show how the public transportation system reform affect the sustainability in transport system.

관광지리학의 대부분의 논문에서는 관광과 교통의 관련성을 설명함과 동시에 그 중요성을 지적하고는 있지만, 그 관계를 중점적으로 다룬 논문은 미약한 실정이다. 제야신도(1975)는 기계적 교통수단이 거주지와 관광대상지 간의 왕복이동 매체로서의 필요성을 지적하였고, P. Lavery(1977)는 교통로와 리크레이션의 형태, 교통로와 접근가능성, 리크레이션 자원으로서의 교통로, 교통로의 관리 등 교통과 관광의 관련성에 대하여 논하였고, 임한수(1992)는 교통이 관광 성장의 원인이자 결과이며, 접근성은 관광지의 개발과 성장에 지대한 영향을 준다는 것을 지적하였다.(중략)

User-centered public transportation services such as DRT, Autonomous Transit etc. have been provied but current minimum level of service for public transportation has been evaluated by the operator because there is no data on user's accessibility to use public transportation. This study was performed GRID analysis using altteul transport card data including user's accessibility to use public transportation. The analysis result showed that user's accessibility to use public transportation was different within a same dong area. We proposed improving minimum level of service for public transportation considered by the user. The result of applying the proposed method showed that many area was changed to unsatisfied area for minimum level of service for public transportation

Cities around the world have paid attention to public transportation as an alternative to reducing traffic congestion caused by automobile usage, excessive energy consumption, and environmental pollution. This study measures accessibility to subway stations in Seoul using a supply-demand-based accessibility technique. Then, the impacts were analyzed through land prices by use and segment. As a result of analysis using the multilevel hedonic price models, accessibility considering both supply and demand for the subway had a positive effect on both residential and non-residential land prices. The effect was stronger for residential than for non-residential. Further, among the accessibility measured by the three functions, the accessibility by the Exponential function was most suitable for the residential land price, and the accessibility measured by the Power function for the non-residential land price had the highest explanatory power. Also, looking at the impacts by land price segments, it was found that higher access to metro stations had the greatest positive impacts on the most expensive segment of residential and non-residential land prices. The results of this study can be applied not only to identify the impacts of public investment on neighborhoods, but also to support real estate valuation.

This paper proposes new algorithms of accessibility indices to analyze the connectivity of the Korean highway network. First of all, we find a transportation network that presents Korea's highway network in graphs in 2011 and 2017. And we analyze and compare the nation's highway network in 2011 and 2017 using concepts such as associated number, the relative distance, the accessibility, the degree of connectivity, the index of dispersion, the diameter of graph theory. To do this, an algorithm is presented which can easily obtain various accessibility indices from a given transportation network. Using the simulation results of this study, we can find city that is the center of traffic in the highway transportation network. In addition, cities that are included in the network but are relatively underdeveloped can be found and used as basic data for enhancing the connectivity of the nationwide traffic in the future. Moreover, the proposed algorithms of accessibility indices, which are modeled on highway transport networks, can help identify the accessibility space structure of each city and provide criteria for efficient and reasonable selection of alternatives in various regional planning processes, including transportation.
