New research highlights inequities in heat adaptation calling for policy changes to address growing heat challenges.

A groundbreaking new study by a team of researchers from Arizona State University, University of Washington and the University of Texas at Austin reveals that extreme heat significantly alters how people go about their daily lives, influencing everything from time spent at home to transportation choices. The study, titled "Understanding How Extreme Heat Impacts Human Activity-Mobility and Time Use Patterns," was recently published in Transportation Research Part D and underscores the urgent need for policy action as cities worldwide grapple with rising temperatures.

The research was led by Ram M. Pendyala, a professor at ASU's School of Sustainable Engineering and the Built Environment, along with co-authors Irfan Batur, Victor O. Alhassan, Mikhail V. Chester and Steven E. Polzin from Arizona State University; Cynthia Chen from the University of Washington; and Chandra R. Bhat from the University of Texas at Austin. The study provides detailed insights into how extreme heat affects daily activity-travel behavior and time use patterns for different socio-demographic groups. It draws on data from the American Time Use Survey (ATUS) and weather data from the National Oceanic and Atmospheric Administration (NOAA), focusing on 11 major U.S. metropolitan areas: Atlanta, Chicago, Dallas, Houston, Los Angeles, Miami, New York, Philadelphia, Phoenix, Seattle and Washington, D.C.
