Number and Rate of Serious Injuries
Updated Using 2023 Data

Number of serious injuries is the total number of people suffering at least one serious or incapacitating injury for each separate motor vehicle traffic crash on Florida’s roadways during a calendar year. The rate of serious injuries refers to the ratio of the total number of serious injuries to the number of vehicle miles traveled (VMT) (expressed in 100 million VMT) in a calendar year. It provides a common denominator to understand the magnitude of the occurrence of serious injuries on Florida’s roadways.

Methodology

Methodology: Number and Rate of Serious Injuries

The number of serious injuries is the total number of disabling/incapacitating injuries (such as broken bones, severed limbs, etc.) from traffic crashes that prevent the injured individuals from engaging in normal activities and that usually require hospitalization and transport to a medical facility.

The rate of serious injuries is the total number of serious injuries on roadways per 100 million vehicle miles traveled (VMT).

Calculation

`"Number of Serious Injuries" = ∑"People Seriously Injured Due to Traffic Crashes"`
`"Rate of Serious Injuries" = (∑ "Serious Injuries")/("Annual VMT") × "100 million"`
