Transition toward sustainablity being in progress in a variety of areas including climate, energy, household, transportation. This study analyzed system transition and backcasting of its management with case of sustainable transportation, foods, household system transition in the Netherlands. Backcasting has become a popular approach for sustainability taking a more reflexive perspective and looking back to the participatory experiments. In the Netherlands, participatory backcasting utilized as s innovative approach for long-term strategy for sustainability, based on stakeholder involvement, construction of normative sustainable futures, stakeholder leaning. In this study, we can be understood that transition management requires the participation and contribution of business, government, research and the public & public interest groups and backcating is tool leading to a sustainable future vision, stakeholder involvement. To create a new path toward sustainablity, it requires integrated consideration of related policy perspectives and participatory backcasting aiming at system innovations for influencing transitions.

The main objective of this paper is to analyze university students' modal shift for commuting trip due to the introduction of new urban rail transit in a satellite city of metropolitan area. The paper uses SP(2011)/RP(2013) data collected from Yeungnam University in Gyeongsan City, which is a satellite city of Deagu Metropolitan City. So far few researches, especially using before-and-after individual SP/RP travel survey, have been conducted on analyzing university students' modal shift due to the introduction of new urban rail transit. For this research, some descriptive statistical analyses were conducted. Furthermore, some empirical logit models were estimated for analyzing factors affecting the modal shift. Finally, some important findings and policy implications are discussed. The significant findings from this research are summarized as follows. From the descriptive statistical analyses of SP and RP data, it is found that the rate of modal shift to rail transit is relatively high especially for bus travellers. Furthermore, from the empirical SP model estimation, it is found that time saving is the most important factor affecting the modal shift to urban rail transit. On the other hand, from the empirical RP model estimation, it is found that residential location is the most important factor affecting the modal shift to urban rail transit.

A diversity of railway network function enhancement projects such as the double tracking, electrification, and direct operation have been actively executed to improve the railway service. When the new rapid railway is provided, how many people will use it instead of other transports? How will the railway choice behavior be changed? Accordingly, in this paper, the applicability of diverted travel demand forecast method by Stated Preference(SP) and Transfer Price(TP) data was reviewed for Daegu metropolitan railway service. As the result of implementing the Revealed Preference(RP) and RP+SP model, the total travel time and travel cost parameters are of the right sign and are highly significant. In particular, when TP data is used as the complementary investigation of SP, the boundary value of diverted travel demand can be easily identified by railway fare and travel time service level. Therefore, it is considered that this will practically apply even in other regions as well as Daegu metropolitan railway.

This study selected blind spot areas for public transportation in four metropolitan cities including Busan, Daegue, Gwangju, and Daejeon. Then this study developed a nested logit model and analyzed the changes of mode choice behaviors after adopting rapid transit system using stated preference(SP) survey. As the study results, blind spot areas have more potential public transportation demand and tendency to shift to public transportation from autos than built-up areas. This study results can be utilized to evaluate demand changes for new rapid transit system in a circular expressway and an arterial highway connecting CBD and surrounding areas. The study results also can be utilized to analyze the potential public transportation demand in the surrounding areas.

The purpose of this research is to identify the factors affecting the intention to adopt a transcontinental railway in Korea. We develop an empirically testable model that demonstrates the effects of factors including cost, service, and efficiency of railway transportation, on modal shift intention to railway, attitude of a Railway, and intention to adopt a Transcontinental Railway (KTAR) as a railway transportation mode in the end. A survey method enables us to analyze the model with a structural equation modeling. The empirical analysis reveals that two most influential factors-the modal shift to railway transportation and the attitude of a Railway-play roles in determining intention to adopt the Transcontinental Railway (KTAR). Of the factors of transportation mode, transportation cost has a greater impact than transportation service and transportation efficiency on the intention to adopt a Transcontinental Railway (KTAR).

The purpose of this study is to evaluate the social costs of inland trucking and maritime transport between Kwangyang Port in Korea and the Great Lakes in US. Also, this study compares these social costs each other, and finds the way how to internalize them for the efficiencies of national logistics policies. This study uses the Contingent Valuation Method to evaluate the social costs for the two transport modes in each country. The final result is that the social cost difference between inland trucking and maritime transport around US Great Lakes area is not so significant that there are not many chances to enhance the maritime transport in the region. However, in case of Korea, there is significant difference in social costs between the two transport modes, so that Korea government may have a lot of chances to improve the seaborne trade by way of various internalization policies.

Analyzing EU trade laws and institutional systems, the trade policy of EU has been founded, undoubtedly, on common interests for EU members. EU trade policy leaves room for 'Collective Protectionism' by permitting legal persona or interesting group to raise anti-dumping procedures. The anti-dumping policy of EU has shown a protectionism itself and has been affected by political motives. Investigation against anti-dumping can easily open and also there exists a wide range of political involvements. Furthermore, anti-dumping policy could be misused for protecting declining industries, which lost comparative advantage in global market. Economic theories show that anti-dumping measures divert import from outsider into insider members, which finally results in increasing intra-production of EU. This is exactly the reason why the anti-dumping policy has become attractive trade policy.

This paper attempted to analyze impacts of transition in electricity generation system on a national economy and environmental level in Korea using a recursive computable general equilibrium(CGE) model. In particular, the paper presented a hybrid model combining the top-down CGE model with the bottom-up model which describes the structure of electricity production in detail. The impacts were analyzed by two policy scenarios base on the basic plan for electricity supply and demand proposed by the Korean government. As a result, the paper specifically showed that there exists a trade-off relationship in the policy-making between economic efficiency and environmental level. The paper also suggested that the transition in electricity generation system should be done more gradually and carefully.

The introduction of a new transit facility affects mode share of travel alternatives. The multinomial logit model, which has been the most commonly used for estimating mode share, has difficulty in reflecting heterogeneity of travelers' choices, and it has a limitation on grasping their characteristics of mode choice. The limitation may lead to over- or under-estimation of the new transit facility and bring about significant social costs. This paper aims to find a methodology to overcome the problem of preference homogeneity. It also applies market segmentation structure of separating the whole population into direct and indirect beneficiary to consider their preference heterogeneity. A mode choice model is estimated on data from Jeju Province and statistically tested. The results show that mode transfer rate of direct beneficiaries that inhabit in downtown areas increases as the new transit facility provides more advanced services with higher costs. The results and the model suggested in this study can contribute to improving the accuracy of demand forecasting of new transit facilities by reflecting heterogeneity of mode-transfer patterns.
