Shibaura Institute of Technology will demonstrate information network infrastructure technologies that realize City as a Service (CaaS). Information network infrastructure will play a leading role in future city planning. In smart cities, especially in CaaS, people will be able to select the "city services" just as you would choose an application on your smart phone. Human flow is a source of economic revitalization because it generates a variety of consumption behaviors. ”Mobility" causing these human flows is the key to optimal urban development. Shibaura Institute of Technology also promotes technologies to reduce risks such as accidents, crimes, and viral infections caused by transportation.
