Drivers are responsible for more than 90 percent of collisions, but we don't know exactly what happens in the moments leading up to a crash.  A new study involving 3100 cars, including many Seattle drivers, is being conducted by Virginia Tech may help answer those questions.  The Naturalistic Driving Study is being coordinated by the Strategic Highway Research Program, known as SHRP 2, which was authorized by Congress to conduct the work, and administered by the Transportation Research Board. The total SHRP 2 budget is around $70.4 million.
