Research conducted by the Department of Geosciences at San Francisco State University indicates 38 children, ages 14 and under, die on average each year in the United States as a result of excessive heat after being left in vehicles. The National Highway Traffic Safety Administration is exploring ways to prevent child fatalities in hot cars. A study by the Children’s Hospital of Philadelphia will evaluate available technologies designed to prevent children from being left in enclosed vehicles by examining how effectively the technology detects the child, alerts the caregiver and influences the caregiver’s behavior.
