A Note on the Influence of Precipitation on Human Flow for the Construction of a Social Disruption Detection System

Abstract

Currently, systems for detecting social disruptions, including natural disasters, have problems such as being able to detect only specific disasters or small social disruptions. In contrast, by analyzing human flow data, which is data on the movement and flow of people, we can expect to build a system that can detect general-purpose social disruptions. In this paper, by using precipitation data in addition to human flow data, we analyze the effect of precipitation on human flow, and report the results of data analysis conducted using both human flow and rainfall.
