1. Project Overview
This project aims to create a heatstroke hazard map to foster a safe and comfortable urban environment even during intense heatwaves. It seeks to support Shibuya residents' activities under extreme heat conditions and contribute to hazard prediction.
2. Background and Challenges
Due to the impact of urban heatwaves, regional challenges include increased risks of health issues such as heatstroke, economic stagnation caused by reduced footfall in towns and shopping districts, and the cancellation of outdoor activities (sports, events, walks, children's outdoor play, etc.). Furthermore, as there can be a difference of 10 degrees or more between the official temperature and the actual temperature on the ground, it is necessary for each individual to accurately know the heat where they are and to create an environment where they can go out comfortably.
3. Implementation
By providing a heatstroke hazard map for the Dogenzaka area near Shibuya Station as a pilot case, we will objectively and with high accurately visualize where and when heatstroke risks occur. Using outdoor temperature data collected from rooftop air conditioning units, we reconstruct the spatial data using a WBGT heat index map at a 5m mesh resolution. This resolution surpasses the resolution of existing administrative indicators and the Japan Meteorological Agency, serving as a key decision-making metric for heatstroke countermeasures.
