Wireless Systems

We investigate and develop a wide variety of wireless communications that are essential for realizing of an environmentally friendly sustainable human society. Our research covers basic theories to real applications, focusing mainly on the total optimization of sensing and control in large-scale systems with wireless communications, which is required in energy/industrial systems, ITS (intelligent transportation systems), and disaster support systems. From the viewpoint of communications media, our scope includes not only radio waves but also optical wireless communications, power line communications, and more.

Transport System

Towards the realization of an environmentally sustainable transportation system considering the widespread use of autonomous vehicles in the near future, we propose that future visions of urban transport systems should explicitly consider the constraints of environmental impact and energy consumption, and develop and evaluate transportation policy measures based on a rigorous understanding of individuals’ travel behaviors. Our research topics include the efficiency of the use of electric vehicles, social acceptance of hydrogen fueling station, countermeasures to reduce traffic accidents, optimum management of urban road traffic using autonomous vehicles, and fulfillment of the mobility needs of mountainous rural communities.

Study on renewable energy and environment and ecology system assessment for achieving sustainable society in harmony with nature

We are conducting research to realize a sustainable society by assessing the impact of energy and the environment. Focusing particularly on land use and spatial evaluation of the natural environment, we are working on the comprehensive solution of problems related to renewable energy( biomass, small-scale hydropower, solar power, etc.), ecosystem services, economy, and society. Along with environment assessments ranging from small-scale field surveys to global-scale assessment, we are engaged in research with an interdisciplinary approach combining, for example, spatial analysis such as GIS( Geographical Information System), AI, UAV, and field surveys.
