In this paper, we mainly describe the development of exclusive u-device essentially required to implement new ITS services (taxi call service, service for transportation vulnerable, transport information service, walker's navigator, electronic payment service, call information service etc.). To design this device, Samsung main CPU S3C2440A was selected and large memories (ROM and RAM) which are required for new ITS services are applied. In addition, all of GPS, RFID module, Wi-Fi and Bluetooth functions are included to develop an exclusive device indispensable in the ubiquitous society. For this, in this paper, we first examined detailed design of an exclusive u-device development, and based on the designed contents, the performance of a realized u-device was evaluated. If services are created by linking new ITS services with relevant public institutions or companies, based on application of the exclusive u-device developed as above, they would be expanded to a new blue ocean, expectedly resulting in a big spillover effect in local societies.

The effects of 5day-work-week have given us strong family relationships by increasing sparing time. People who visit national parks enjoy the intimate with family. Especially, the public park has much benefits, such as people visit easily with moderate prices. This research is focused on the sign-design to increase watching effects with low price. However, there are some problems suck as assignments of sign without much considerations for moving line, unmatched with circumstances, lacking of consistency images. Thus, the effect of entertaining is decreased. For this, the paper analysis large-scale public park and large-scale private parks, and solves the several kinds of the problems. We also classify the types of sign designs and propose the sign design methods on characteristics. Therefore, we provide the objectivity of proposed sign designs by evaluating conveniences and expectations, and proposed the design methods of public parks and private parks.

This study is to improve the design of bus transfer information that can be substantially used. This study has been processed using the following steps. First, I tried to define the information design and way-finding information design. Secondly, I have researched several case studies, and considered solutions. Finally, I evaluated way-finding maps through pair-wise comparisons, and drew needs through an interview. As the result of this research, there were some problems in font size, improper space between letters and non-consistent information. To solve these problems, the information has to be clear using easy symbols to be well-recognized by citizens. Also, the font size needs to be decided by a calculation of minimum legible size of letters. Lastly, a value contrast between a background color and a letter color needs to be applied more than 70 percent for better visibility. The study is expected to be used as a reference which helps informational design to be developed.

Recently, analysis techniques to extract new meanings using big data analysis and various services using these analysis techniques have been developed. Among them, the transport is one of the most important areas that can be utilized about big data. However, the existing traffic route guidance system can not recommend the optimal traffic route because they use only the traffic information when the user search the route. In this paper, we propose a realtime optimal traffic route guidance system using big data analysis. The proposed system considers the realtime traffic information and results of big data analysis using historical traffic data. And, the proposed system show the warning message to the user when the user need to change the traffic route.

In this paper, we design and implement a product information guidance system Based on BLE beacons. This system is designed to provide various functions such as contactless entrance service through mobile ticket, seat guidance service, event push service, content push service, and public service. This system consists of three modules: a beacon recognition module, a server linkage module, and a content transmission module. The beacon recognition module implements a function of transmitting a specific ID of a nearby beacon when a customer with a smartphone approaches the available service area. The server linkage module recognizes the beacon ID value, transfers it to the server, and implements the function to check the location of the server having the ID. The content transmission module implements a function of transmitting event or service information set at a corresponding location to a smartphone. The beacon-based product information guidance system implemented in this paper has the advantage of being able to quickly and easily implement various product information guidance systems.

Contributed acceptance system is causing problems with the usefulness and follow-up services and the like, other than the origin purpose which needs to be operated as rational adjustment method between the public interest and the private. Accordingly, this study has examine the problems by analyzing the present condition of practical public facilities and has the purpose on drawing the improvements by conducting consciousness survey from in substance users. The problems drawn from the analysis and the survey are location and position of the public facilities by reason of making public facilities at leftover land, the awareness and use as in-site facilities, creating street facilities without considering the use and safety of the users, follow-up service issues and the usefulness issues by creation without considering the surrounding conditions. The proposal of improvements for efficient operation by each problems are devising plans by considering location and position of the facilities for utilization and usefulness, secondly the necessity of the public relations for the improvements of the utilization of public facilities. thirdly, conducting the legal obligation by installing direction boards for its awareness of public facilities and delegating operation of facilities to public corporations such as SH, LH and inhabitants for efficient follow-up services, lastly, establishing the public facility map service which could figure out the surrounding conditions of public facilities to utilize for the contributed acceptance.
