This paper proposes a vehicle trajectory prediction method for application to vehicle-to-vehicle distance control. This method is based on 2-dimensional kinematics and a Kalman filter has been used to estimate acceleration of the object vehicle. The simulation results using the proposed control method show that the relative distance characteristics can be improved via the trajectory prediction method compared to the customary vehicle stop and go cruise control systems which makes the vehicle remain at a safe distance from a preceding vehicle according to the driver's preference, automatically slow down and come to a full stop behind a preceding vehicle.

A vehicle cruise control algorithm using an Interacting Multiple Model (IMM)-based Multi-Target Tracking (MTT) method has been presented in this paper. The vehicle cruise control algorithm consists of three parts; track estimator using IMM-Probabilistic Data Association Filter (PDAF), a primary target vehicle determination algorithm and a single-target adaptive cruise control algorithm. Three motion models; uniform motion, lane-change motion and acceleration motion. have been adopted to distinguish large lateral motions from longitudinal motions. The models have been validated using simulated and experimental data. The improvement in the state estimation performance when using three models is verified in target tracking simulations. The performance and safety benefits of a multi-model-based MTT-ACC system is investigated via simulations using real driving radar sensor data. These simulations show system response that is more realistic and reflective of actual human driving behavior.

In this paper, results of an analysis of driving behavior characteristics and a driver-adaptive control algorithm for adaptive cruise control systems have been described. The analysis has been performed based on real-world driving data. The vehicle longitudinal control algorithm developed in our previous research has been extended based on the analysis to incorporate the driving characteristics of the human drivers into the control algorithm and to achieve natural vehicle behavior of the adaptive cruise controlled vehicle that would feel comfortable to the human driver. A driving characteristic parameters estimation algorithm has been developed. The driving characteristics parameters of a human driver have been estimated during manual driving using the recursive least-square algorithm and then the estimated ones have been used in the controller adaptation. The vehicle following characteristics of the adaptive cruise control vehicles with and without the driving behavior parameter estimation algorithm have been compared to those of the manual driving. It has been shown that the vehicle following behavior of the controlled vehicle with the adaptive control algorithm is quite close to that of the human controlled vehicles. Therefore, it can be expected that the more natural and more comfortable vehicle behavior would be achieved by the use of the driver adaptive cruise control algorithm.

Information Warfare(IW), a new aspect of war, is the field centralized the concern and research in the information security and national security, Both the defense and the offensive are important in the next generation IW, and so we need to do the various research to secure the network and system for gaining the superiority of IW. This paper proposes a model for IW based on software cruise to prepare the IW that is changing the offensive aspect. Software cruise is defined as a behavior of computer programs that travel toward specific destination from a source through the network. The proposed model have the cruise property and uses the cybermap to cruise toward the destination chosen in advance. Also, while self-movement, the model can function the predefined task.

The recent rapid increase of international ocean cruises calling at Korea has prompted the interests of central and local governments in promotion of cruise ship tour. Korea's cruise tour policies and facility improvement plans tend to be focused only on main ports of cities with high calls at cruise port, such as Busan, Incheon, and Jeju. However, small and medium-sized ocean cities which represent the coastal areas are also seeking to activate cruise ship tour and attract investment, and therefore they merit governmental support as well. This study looks at the current conditions of cruise tourism in small and medium-sized ocean cities and searches for the means to activate cruise tours. It suggests improvement policies for port services, transport accessibility, urban facilities and tour activity support, as well as expected roles of public and private sector. As a case study of Yeosu in Jeollanam-do, it analyzes the present state and discusses possible future activation programs, comparing small and medium-sized cities with cities with main ports. In order to be a port of call, steady exertions for improvement are required in all areas regarding cruise tourism whether it's main or local. Especially, since local ports in small and medium-sized ocean cities are relatively unlikely to be developed into home ports, policies and tourism programs should be established to support them in being chosen as ports of call.

This study is to explore the characteristics and trends of the interior design of the residence area of the cruise ships. The interior of the cruise ships running three Asian countries - Korea, Japan and China was analyzed to understand the design of the public area and the cabin area. The interior of the ships showed the modern, high-tech style with their unique concept. Also, the feeling of the openness was emphasized in two ways- the visual and psychological expression and the spatial application. The contrast of color and the effect of artificial lighting used to express the extended feeling of the closed space inside the cruise ship. The results are expected to contribute to understand the interior design of the worldwide cruise ship and be used as a valuable data for the development of the interior design of the cruise ship.

From the day of luxurious inland river cruise ship started in Chongqing, China, the controversy is continuous; some people think those luxurious cruise ships on inland river might reduce the experience to enjoy the scenery of the Three Gorges, while some people think, which could improve the experience. In the study, the service facilities provided by luxurious inland river cruise ship will be evaluated by Pre-Post comparison based on IPA methods. After a review of the service facilities provided by luxurious inland river cruise ship running on Three Gorges areas. The tourists who would take the trip were asked to fill an questionnaire to examine the desired service facilities performance, which represents the highest level of the service facilities of the cruise ship that is expected by customers. After the trip, they were asked again to fill another questionnaire to examine the importance of service facilities and the performance of service. Pre-Post comparison would be examined to tell whether there is any change between pre and post experience. IPA would be used to evaluate the service facilities provided by inland river cruise ship. At last, some strategic suggestions to the development of inland river cruise ship are made.

The study investigated how an adaptive cruise control system induced behavioral adaptation in drivers using a full-scale driving simulator. Forty drivers with different driving styles participated in the study to compare headway-time, vehicle lateral position variation, and head and eye movement when driving with and without the adaptive cruise control system. Results showed that system induced positive behavioral adaptation by drawing consistency in driving speed and headway-time regardless of the driving styles. However, the results also showed that the drivers' reliance on the system induced negative adaptation including reduced lane keeping ability and reduced attention during driving. As a strategy to prevent negative adaptation, the study proposed information service to drivers with the adaptive cruise control system status and driving environment, and investigated effectiveness of the service. Twelve drivers participated in the experiment to compare headway-time, vehicle lateral position variation and subjective ratings when driving with and without the information service. Results showed that the information service assisted the drivers to maintain safer and more comfortable headway-time without impairing drivers' steering ability.
