The present study was conducted to analyze transport mode choice factors of shippers in Korea and to suggest policy implications and directions for future research. The findings showed that the research on freight mode choice factors in Korea is somewhat insufficient compared to that of other countries. In order to enhance the research, it is necessary to expand the number of studies and to strengthen the research to reflect characteristics of each transport mode. In particular, it is necessary to focus on identifying the characteristics of multimodal transport, including railway and shipping linked to truck. On the other hand, it was confirmed that the major factors influencing the choice of transport mode of shippers in Korea overlapped with foreign research cases. In addition, the implications for policy were derived when the analysis was separately conducted for Korea and other countries regarding individual transport mode and transport range. These results could be applied to various fields such as policy making to improve the efficiency of shippers' selection of transport mode and the estimation of transport mode choice model.

In order to organize the Intelligent Transport System(ITS) as a communication equipment, the satellite and wireless system demand broadband characteristics for collecting information from the wide road. Band-pass filters (BPF) or broad BPFs used in such communication system are required for broadband characteristics. This paper presents a design of such broad BPF which can be used in the system. Designed BPF which was difficult to get broadband characteristics after realization, become possible to realize filter with broad bandwidth and compact structure using parallel coupled line. The designed filter achieved the insertion losses improved by 0.4 dB and the return losses improved by 17.4 dB respectively with 60% of bandwidth at the 5.8 GHz of the center frequency, respectively.

C-ITS is a system that uses bidirectional communication between two vehicles or infrastructures to control traffic more conveniently, and safely. If C-ITS security is not properly prepared, it can cause traffic congestions and fatal traffic accidents, and therefore can affect greatly on the driver's life. This paper proposes the prevention and response mechanisms based on the cyber attack scenarios that can be used to attack C-ITS.

In this paper, Korea's standardization capacity in the ITS field was examined, and the status of participation in ITS standardization and services of ASEAN countries, and the degree of hope for cooperation with Korea was investigated and analyzed. Korea is recognized for its international competency in the field of ITS standardization, and most ASEAN countries, excluding Singapore, are found to have insufficient participation in ITS standardization and service introduction. In addition, most ASEAN countries are strongly hoping for ITS standardization cooperation with Korea, and the preliminary establishment of the ITS system architecture as the basis for ITS standardization was derived as a project of hope for cooperation. In addition, as a service field for introducing standardization, Freight transport was suggested as a priority application service field in order to improve the efficiency of logistics transportation between ASEAN countries.

There are many problems of interoperability between ITS system equipments since the protocol standard for a network center and a node has not defined. In this paper, we consider the use of the SNMP to solve the interoperability problem, and apply the SNMP in the case of a CCTV as an example. Also, we defined its corresponding MIBs and accomplished the interoperability test, where the method of controlling the CCTV is explained and the data transmitted on the network are shown in a hexadecimal format. Our results are expected to be helpful for a guideline or feasibility test as nationwide data to support the interoperability of ITS systems between a network center and nodes.
