In the state of Texas alone, there were a total of 415,892 traffic collisions, including 3,005 fatal crashes in 2012. In Canada, they are the cause of 48% of severe injuries. Crash rates
The safety performance of roadways is almost always reported as a rate. That is, some measure of harm (deaths, injuries, or number of crashes) divided by some measure of exposure to the risk of this harm. Rates are used so the safety performance of different locations can be compared, and to prioritize safety improvements. Common rates related to road traffic fatalities include the number of deaths per capita, per registered vehicle, per licensed driver, or per vehicle mile or kilometer traveled. Simple counts are almost never used. The annual count of fatalities is a rate, namely, the number of fatalities per year. There is no one rate that is superior to others in any general sense. The rate to be selected depends on the question being asked – and often also on what data are available. What is important is to specify exactly what rate is measured and how it relates to the problem being addressed. Some agencies concentrate on crashes per total vehicle distance traveled. Others combine rates. The U.S. state of Iowa, for example, selects high collision locations based on a combination of crashes per million miles traveled, crashes per mile per year, and value loss (crash severity). Fatality
The definition of a road-traffic fatality varies from country to country.
