The authors showed that the public’s response to terrorist threats can have unintended consequences that rival the attacks themselves in severity. Driving fatalities increased significantly after the September 11, 2001 terrorist attacks, events that prompted many travelers to substitute road transportation for safer air transportation. After controlling for time trends, weather, road conditions, and other factors, the authors found that travelers’ response to 9/11 resulted in 344 driving deaths per month in late 2001. Moreover, while the effect of 9/11 weakened over time, a total of about 2,170 driving deaths may be attributable to the attacks. (Author/publisher)
