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

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)

The purpose of this study is to analyze the effect of public transit accessibility on the Carsharing use demand. By utilizing the rental historical DB of Greencar which is operated in Suwon city and public transit GIS DB, the use demand models for Carsharing by rental offices are built and analyzed in accordance with public transit accessibility. The result indicates 73% of walking as a majority, 3% cycling, and 20% using buses and urban railways to access Carsharing rental offices. The goodness of fit of Carsharing use models reflecting accessibility to buses and railways is verified as 0.818 which proves that public transit accessibility is a significant variable. Therefore, it is verified that installing Carsharing rental offices where public transit transfer is convenient can possibly increase the use demand. Especially, while accessibility to buses is verified as a significant variable out of other public transit means, the accessibility to urban railways is verified as not significant. This suggests that a variety of complementary policies such as transfer discount policy and one-way transfer return policy are necessary in between urban railways and Carsharing in order to promote mutual use demand in accordance with the other public transit means. This study result is yet the basic research on Carsharing, however it is expected to contribute to improvement of transfer demand in between different public transit means.

Fare is critical variable when deciding project feasibility for a monorail system in tour regions. This study aims to estimate optimal fare balancing operators and users. An object of this study is Wolmi-eunha circulation monorail at Jung-Gu, Wolmido in Incheon metropolitan city. This study introduces a stepwise optimization technique to decide relevant fare ranges between operator's cost and user's cost. We found that the optimized station interval is 0.532km, the optimized headway is 0.206hour, optimal number of stations is 12, optimal number of vehicles is 3. Using these optimized variables, minimum user cost and minimum operator cost can be calculated. Optimal fare range is calculated from 1,261 Won to 5,063 Won. It is also found that sightseeing transport system has less sensitivity on access cost because distance differences among sightseeing transport stations located in the tour regions are negligible.

우리 헌법은 인간의 존엄과 가치 그리고 행복을 추구할 권리를 보장하고 있으며, 편의증진법과 교통약자법을 통해 장애인등이 교통수단, 여객시설 및 도로 등을 비장애인들과 차별 없이 이용하여 이동하고, 도로와 대중교통수단, 공공 건축물과 주거 등 생활 필수시설에 자유롭게 접근하기 위한 접근권을 보장하고 있다. 우리나라는 이동권의 보장을 편의시설 제도라는 독자적인 체계를 통해 이루어지고 있으며, 이를 실질적으로 보장하기 위하여 장애물 없는 환경 인증 제도(BF 인증제도)를 도입하였다. 시행 15년을 맞은 BF 인증제도는 양적으로는 많은 발전을 가져왔지만, 질적으로 특정 건축물 등 일부에 대한 인증 편중 현상이 있으며 안전취약계층에 대한 재해 안전확보에 대한 고려가 포함되지 않아 부진정한 이동성과 접근성의 보장이라는 한계를 가지고 있다. 이동권 보장이 얼마나 잘 이루어지느냐는 그 나라의 사회 안전망이 얼마나 잘 갖추어져 있는지 판단하는 척도라 할 것이며, 따라서 이러한 이동권 보장은 위험상태에서의 안전한 피난을 함축하고 있으며 중첩적으로 국가의 기본권 보호 의무의 이행과 관련된다. 이에 따라 이동권과 접근권의 증진을 위한 BF 인증 규정을 안전 규범으로 보완하여 장애인과 비장애인이 사회의 일원으로서 평등한 인격적 주체로 공동체에 기여하는 안전한 사회적 환경의 조성이 긴절히 요청된다고 할 수 있다.

This study suggested a method of forecasting market-share of each mode after introducing new urban rail transit lines. The study reflected the observed market share of presently operating urban rail transit into forecasting process in order to improve accuracy in predicting market share of each modes. For more realistic representation of the forecasting model, we categorized O/D pairs according to attributes of trip distance, access time and number of transfers. The analysis results of traveler's mode choice behavior with observed data showed that the trip distances are longer, the share of urban rail tends to be higher, and that the number of transfers is fewer and the access times are lesser, the share of urban rail also tends to be higher. Then, incremental logit model was used in estimating mode choice probabilities for O/D pairs along with rail transit lines while utilizing observed market shares of each modes and differences in transit service level. As the next step, the market share of rail transit after introducing new rail transit lines was forecasted by using incremental logit model with the intial share values calculated the previous analysis step. It also reflected changes in level of service for automobile in highway due to changes in highway systems and changes in mode shares after introducing new lines of rail transit. It can be expected that the proposed method would more realistically duplicates phenomena of mode choice behavior for rail transit and that it would be more theoretically logical than the typical existing methods using SP data and incremental logit model or using addictive logit model in this country.

Analyzing mode choice among transportation demand estimate procedures is complicated and understanding characteristics of travelers is also difficult. Generally, it is well known that traveler choose mode considering psychometric factors and characteristic besides socio-demographic indicators. Accordingly, many researches has investigated on methodology that can be applied in mode choice to reflect psychometric factor or specific preference. Latent Class Analysis among various studies is recognized as the theoretically potential approach. This study focuses on class segmented using latent class cluster to analyze impact that included psychometric factors and characteristics on mode choice. It also provides evidence that mode choice model for each class and mode choice model not considering latent class are different. This study based on citizen's stated preference and revealed preference on a new transit on the Han river shows that latent class cluster analysis is the potential approach considering latent preference.

This study analyzes the changes in commuter's mode choice between 2002 and 2006 according to the implement of the integrated public transit system in Seoul metropolitan city. Especially this study focuses on differential changes in a transit modal choice among socioeconomic status, trip purpose and spatial characteristics of origin and destination. The probability of public transit use against automobile is modeled as a function of socioeconomic variables, spatial characteristics of origin and destination and the utility of the commuter's mode. The results from conditional logit model analyses suggest that people with lower income show the larger changes in the ratio of public transit choice between 2002-06. Also both higher density, more accessible to public transit and more diverse land uses in residence zone and in work place generally increase the ratio of public transit choice between 2002-06. Car and subway have the most strong alternative relation in commuter's mode choice. The findings give an important implication that the integrated public transit system has differential impacts on commuter's mode choice in Seoul.

This research deals with the multi-modal continuous network design problem to resolve the transportation policy problems for constructing and operating transportation facilities with considering the mutual decision-making process between transportation operator and user in the multi-modal network. Particularly, in the consideration of changes in travel pattern between transport modes due to the changes in transportation policy, road network for passenger car and transit network for public transportation are considered together. In the development of network design model, more rational Stackelberg equilibrium(cooperative game) rather than more general Nash equilibrium(non-cooperative game) approach is used and sensitivity analysis considering transport mode is used. A multi-modal continuous network design model in this study is developed for the arbitrary continuous network design parameters(${\epsilon},\hat{\epsilon},p$) of transportation policy decisions. As examples of application and evaluation for these design parameters, the developed model is applied to calculate 1)the optimal capacity of road link in the road transport policy, 2)the optimal frequency of transit line in public transport policy and 3)the optimal modal split in transport modal share policy.
