In modern cities, the deterioration of the heat environment in urban areas and the increase in the number of heat stroke victims caused by extreme heat are social problems.The local government provided us with detailed information on outdoor heat stroke damage.The heat conditions in the streets were estimated by numerical simulation using QGIS.These were compared, and the results were used to determine the level of heat stroke risk.As a result, we were able to show that MRThour, which is the time integration of MRT distribution in the city, is effective in indicating the degree of risk of heat stroke.Furthermore, by using the location information of cell phones as pedestrian information, we were able to extract the danger zone of Sannomiya.
