Data Collection
There are a number of organizations that collect data on the number of collisions and crashes. Some of these include:
– The National Highway Traffic Safety Administration (NHTSA)
– The Insurance Institute for Highway Safety (IIHS)
– State Departments of Transportation (DOTs)
Each of these organizations has different methods for collecting and reporting data, so it is important to compare and contrast their findings. The NHTSA, for example, uses police reports to compile its data, while the IIHS relies on insurance claims. State DOTs use a variety of methods, including police reports, hospital records, and self-reported surveys.
Examples
New report shows how many accidents, injuries collision avoidance systems prevent
The Institute for Highway Safety (IIHS) conducted a study to measure the number of collisions/crashes using collision avoidance systems. These systems have shown that they prevent some of the deadliest accidents on the road because they give the driver time to avoid a crash. The IIHS analyzed more than 5,000 accidents in 2015, even though there were warning systems to prevent these accidents from happening. From the findings of the study, IIHS recorded a 21% reduction in the number of collisions, which was due to the collision avoidance systems. The IIHS clarified that if these systems had been made available earlier, there would have been an aversion of over 55,000 injuries.
