In this paper, we introduce a road surface conditionunderstanding and sharing system. Traffic accidents and obstructionsdue to bad weather conditions and poor road conditions areserious social problems. It is necessary for drivers to understandweather and road conditions in advance to avoid traffic accidentsand obstructions and it is necessary to alert drivers to weatherand road conditions in order...
Tourism is one of important resources in Japanese economy. The number of tourists has been increasing year and year. And the divergence and personalization for tourists are required and new tourism function and deployment are expected to attract those tourists. In this paper, we suggest a new tourist information system, by the augmented reality using the information of the beacon which can provide...
Tourism resources are one of the most significant resources in Japan. It is necessary for the continuation of continuous sightseeing industry to utilize the attractive point in an area in which I have such diversity. However, maintenance and management are not accomplished to utilize such contents as a tourist spot. It is hard to the cost and hand's point by a conventional way by a local resource...
With the recent rapid growth of V2X (Vehicle-to-X) developments, there are many expectations for the purpose of safety driving, road guidance, and the road surveillance system during the winter. However, in case of the road surveillance system during the winter, there are some difficulties for the recognition of the frozen road conditions by the current sensor system such as the locations or elapsed...
This paper identi es metrics that can be used in the operation phase to realize a platform to facilitate the development of services for smart mobility. The paper analyzes requirements of the platform for smart mobility using the I* framework which facilitates identi cation of goals between stakeholders. We conduct goal-question-metric(GQM) identifying metrics, which can evaluate whether the application...
In this paper, we introduce an estimation of communication range using Wi-Fi for V2X communication environment. Traffic accidents and traffic hazard are serious social problems. Understanding road condition in advance is important and necessary to prevent traffic accidents and traffic hazards. In addition, getting information without Internet connection is necessary to provide road information for...
The road conditions during the winter especially in mountain areas are one of the significant safety subjects for the residences and the tourists. However, there are still many places where the wireless networks such as 3G and LTE are hard to connect in the mountain areas, and it is also difficult to keep continuous data transmissions during the nodes are moving. Therefore, this paper proposes the...
In this paper, we introduce an experimentation of V2X communication in real environment for a road alert information sharing system. Traffic accidents and traffic hazard are serious social problems. Understanding road condition in advance is important and necessary to prevent traffic accidents and traffic hazards. In addition, getting information without Internet connection is necessary to provide...
In our study, we develop a road condition monitoring system using multiple sensor data based on Software Defined Network (SDN) for Intelligent Transport System (ITS). The road conditions on both normal and disaster cases are monitored and collected to the cloud server to provide in public through the Web page on Internet, but also exchanged between the vehicles running on the same road in realtime...
The road conditions during the winter especially in mountain areas are one of the significant safety subjects for the residences and the tourists. However, the network services such as LTE or 3G are not available as the urban areas. Therefore, this paper proposed the Area of Interest (AOI) for Vehicle-to-vehicle (V2V) based the Delay Tolerant Networks (DTN) of the road surveillance system. In the...
In this paper, we introduce a road alert information sharing system with multiple vehicles using Vehicle-to-Vehicle communication considering various communication network environment, which is named SODiCS (Spatial and temporal Omnidirectional sensor data Distribution and Collection System). Japan is prone to natural disasters. In addition, traffic hazards and traffic accidents occur due to snow...
In Japan, large scale earthquakes frequently occur. At the occurrence of disaster, network infrastructure is often seriously damaged and traffic congestion occurs. Particularly since the network communication environments of mountain areas are not well developed, it is difficulty to normally use the communication means once the disaster happened. We have investigated the network communication method...
The advance in the mobile terminal and wireless communication environment enables practical use of recommendation systems in tourism. A recommender system is a kind of information filtering system that helps users to find the optimal information from vast amounts of information using user preferences, environmental contexts, and user contexts. To carries out the optimum recommendation, Recommender...
Recently, the number of automotive sensors has increased with the spread of electronic control systems such as driver assistance functions, navigation systems and hybrid systems. Time-Spacial automotive sensor data from various environmental and internal information of a vehicle is used for many vehicle control functions and services for passengers. To handle such time-spacial sensor data, we propose...
In this paper, we introduce a road condition sharing system using Vehicle-to-Vehicle communication in various communication environment. Japan is prone to natural disasters. In addition, traffic hazards and traffic accidents occur due to snow. A wide range and quick condition understanding and monitoring are needed. In addition, it is important to understand the condition of the destination and the...
In northern areas, the road conditions during the winter especially in mountain areas are one of the significant safety subjects for the residences and the tourists. In addition, there are some areas that the network services such as LTE or 3G are unavailable to use in mountain areas. For this reason, this paper proposed the Vehicle-to-vehicle (V2V) communication methods with the Delay Tolerant Networks...
Angiosarcomas are extremely rare vascular neoplasms. The overall prognosis of angiosarcoma is poor because it generally presents as an aggressive neoplasm with a propensity for local recurrence and early distant metastasis, even when multimodality therapy is provided. Because of this aggressive behavior, it has not been possible to identify the optimal treatment for angiosarcoma. The CyberKnife system...
In our study, we develop a road condition monitoring system using multiple sensor data considering various communication environment, which is named SODiCS (Spatial and temporal Omni directional sensor data Distribution and Collection System). Japan is prone to natural disasters. In addition, the areas that have a lot of snow are prone to traffic hazards and traffic accidents occurring due to snow...
Recently, the rapid technological growth of automobiles expects us to the various usages for the near future, and V2V communication is also a part of novel technologies to realize novel usages as well as ITS. This paper proposes the V2V communication with Delay Tolerant Networks (DTN) for safety surveillance system in the local area during the winter season. In the proposed system, the automobiles...
Time-Spacial automotive sensor data from various environmental and internal information of a vehicle is used for many vehicle control functions and services for passengers. To handle such time-spacial sensor data, we propose and develop an automotive sensor information platform named CoMoSE, which provides the utilized methods of automotive sensor information and serves the various services. In this...
