| Outline of Final Research Achievements |
We analyzed the GPS data of about 1 million people and clarified the basic characteristics of the flow of people in the metropolitan area. We have established a new data analysis method that captures the pattern of human flow in a metropolitan area from the perspective of drainage basins. We found universal characteristics in which the size distribution and shape of the basin do not depend on the city. It was found that the basic characteristics were maintained even under the infection of Covid-19.In addition, we constructed an electric circuit model that approximates the traffic flow in the metropolitan area by analogy that regards the human flow as an electric current, and built the foundation of a new simulation method of macroscopic human flow. In addition, we improved the basic mathematical model of infectious diseases to take into account the effects of population concentration based on GPS data, and developed a model that can predict the number of infected people.
