About Paper:

With increasing extreme heat events due to global warming, extreme heat poses a pervasive threat to various facets of life. It is important to understand the impacts of extreme heat on human behavior. This study is to explore how extreme heat events influence people's mobility patterns. We calculated heat index values across the United States during the summer of 2023. Our sensitivity analysis identified locations that experienced extreme heat with a threshold of 48 hours of a heat index of 95 degrees during the daytime and 75 degrees Fahrenheit during the nighttime. Comprehensively, considering the social vulnerability index (SVI), hours under extreme heat, population density, and geographical location, we finally selected St. Louis, Missouri, as the area of interest for this study. Further analysis will include additional parameters such as tree canopy rates and transportation network density in a regression model to examine differences in mobility across various groups during heat waves. We also aim to explore people's mobility needs for different points of interest (POI). This study can deepen the current understanding of how extreme heat affects urban mobility, aiding urban planners in improving accessibility for all populations, particularly those at higher risk during heat events.
