Among domestic car carrier operating shipping companies, some shipping companies are operating a stowage planning system that is installed and executed on a computer, and most shipping companies are executing stowage plans with documents such as Excel. This is a study on how to utilize web service technology so that multiple users can use the planning system more efficiently in the cargo stowage planning process for car carriers.

Domestic car ferries do not operate a dedicated information system for cargo loading and management, It is impossible to arrange according to the cargo type and quantity at the time of cargo reservation due to restrictions such as the need to comply with the cargo layout drawings in advance approved by the Korean Register. For this reason, this is a study to utilize similar information systems in operation in container ships and terminals for the purpose of improving cargo shipment management tasks for car ferries.

A car navigation system as an in-vehicle route guidance information (RGI) offers a state-of-the-art technological solution to driver navigation in an unfamiliar area. However, the RGI is provided by some pre-determined options in terms of the interface between a driver and a car navigation system. Drivers occasionally pass the target intersection owing to non- or late- recognizing it. This paper is examined the position of driver's turn signal operation and intersection recognition approaching at the target intersection which is difficult to identify, as a fundamental research on developing the additional RGI connecting with the turn signal control. The field experiment was conducted to measure distances of the turn signal operation and the intersection recognition from the target intersection according to left turns, right turns, and landmarks at adjacent intersection. And glance behavior to the car navigation display was evaluated by using an eye camera. The results of the field study indicate that, most case of driving, drivers operate the turn signal until 40m to 50m before coming to the target intersection. The driving simulator experiment was performed to examine the effectiveness of providing the additional RGI when drivers did not operate the turn signal approaching at the target intersection based on the results of the field study. To provide the additional RGI is effective for the intersection identification and recognition, and expected to improve the traffic safety and the comfort for drivers.

Many ships' collision accidents occur due to unlawful action at sea. And also at shore traffic, many car collision accidents occur due to unlawful action. Therefore In this study we analyzes actual collision accidents at sea with the regards of liability. and search and analyze similar car collision accidents at shore traffic to compare it with the ship collision. In result, this study suggests the liabilities of the two different types accidents are needed to change more reasonable liability apportionment.

Significant advancements in technology enhanced the reliability of navigation systems that are in use today. The GPS is the most widely used technique for satellite-based location estimation. However, systems based on GPS can only be accurate in providing location data when there is a clear view of the satellites. This paper proposes a self-contained navigation system that does not depend on any tracking infrastructure. Using the built-in sensors of a smartphone and a self-contained map, we implemented an accurate car locator. Evaluation results show that our proposed system outperforms GPS in providing accurate car location assistance.

We analyzed the technology portfolio matrix for the car navigation technology using QFD method and accordingly suggested the navigation technology development direction. QFD is a useful tool to analyze the customer demands and the technologies. Depending on the survey results from the latent customers and the technology capabilities from the study of the national institutions, we suggested technology portfolio matrix. The visual HMI technology, safe driving support technology, and the navigator information management technology are the most prospective area for R&D investment according to the portfolio matrix.

The operated type of navigation is composed of hardware or software. The navigation based on software is stored and ran in the external storage(e.g. SD card). For the convenience of users, Many car navigation systems store user information such as frequently visited place, route, and so on. Those can be used to proving the alibi of users as well as their relationship between the actual owner of the vehicle through data and time information analysis. Therefore, if it is analyzed datas of navigation, we can get a lot of information such as user's movement, route of car. There are important implications in the digital forensics because it's available for investigating the various crimes. This paper demonstrates the necessary information in the digital investigation through the analysis of stored data in the navigation.

We design level 1 traffic thematic map for common data structure. Level 1 means the road that can passing cars. If public office and private company use this form, they can save amount of money from overlapping update. And widely use of traffic analysis, navigation and traffic information system. For design common data structure we compared several data structure(traffic thematic map, ITS standard node/link, Car navigation map), and generalization these characteristic data. After generalization we considered about application parts. It can use of public part(traffic analysis, road management, accident management) and private part(car navigation, map product, marketing by variable analysis) etc.
