  • The Arctic transportation offers big opportunities as shorter transport distances, less fuel consumption, less carbon emissions, faster deliveries of goods, and more profits. The present study is aimed to investigate a future flow to deal with policy in arctic transportation using Big data analysis.

  • There is a need to provide appropriate transportation safety services to foreigners residing in Korea. The main purpose of this study is to enhance transportation safety services for foreigners. In order to identify the risk of traffic accidents, analysis of traffic accidents was conducted using a survey of foreigner travel behavior. According to the results of this model, the study suggests directions to achieve improvement of traffic safety services for foreigners who are unfamiliar with the transportation systems. The study results show that the risk of traffic accidents is influenced by two factors: comprehension of transport geography and of traffic laws. Necessity of policy is influenced by two factors: comprehension of transportation system and the risk of traffic accidents. Intention of using policy is influenced by two factors: the risk of traffic accidents and necessity of policy. Effect of policy is affected by the intention of using policy. The results also demonstrate that the traffic safety services for foreigner can be described as endogenous variables which are approximately 88% of the traffic safety education, 85% of the demanded multicultural district, and 75% of the portal traffic information. Compared with existing research, this study provides a systematic methodology to evaluate effects and the order of priority in establishing traffic safety policies for foreigners.

  • 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.
