With vehicle crashes as the leading cause of injury-related death in the United States for people between 1 and 65 years old, high-quality transportation research is essential to public safety. Researchers are working to provide information that would help prevent the more than 40,000 deaths and 2 million injuries, and the $150 billion cost of crashes each year.
Until recently, research has been confined to analysis of police-reported crash data and studies conducted on test tracks and in simulators. While these methods can be effective, there is no substitute for collecting data in a real-world, or naturalistic, environment.
So, for a year, researchers at VTTI observed the actual daily driving habits of 241 drivers. It was the first instrumented vehicle study undertaken with the primary purpose of collecting large-scale naturalistic driving data.
“Due to the unpredictability of driver performance and the random nature of automobile crashes, the collection of naturalistic data gives a more accurate perspective of why crashes occur,” says Tom Dingus, director of VTTI and program manager for the study.
