Serious Injury Crash Rate

Value: 11.35 serious (incapacitating) injury crashes per 100 MVM traveled
Measurement Period:


Location: Allen County
Categories: Transportation / Personal Vehicle Travel Transportation / Public Safety

What is this Indicator? This injury crash rate performance measure depicts the annual change in the rate of serious (incapacitating) injury crashes in Allen County traffic crashes as a function of 100 MVM traveled. 

Why this is important?  In terms of both personal loss and financial impact, serious (incapacitating) injuries are the most devastating to the people and families involved as well as to the community.  Tracking the serious injury crash rate enables planners to compare traffic safety in terms of fatal and incapacitating injury crashes occurring in Allen County, to the same unit of measure in other counties, states, or at the Federal level.  In addition, it enables traffic safety professionals to compare the rate of serious injury crashes occurring on different roadways within Allen County, since it relates the number of such crashes to exposure levels, i.e. miles driven. Examining the serious injury crash rates allows planners, engineers, law enforcement, as well as emergency responders to identify and improve problem areas.

Technical Note: A rate is a certain quantity one measures as a function of another such as time or length. An example: if two roadways have the same number of serious injuries but different traffic volumes, the resulting rate calculation will indicate which roadway is more, or less, safe than the other. This data can be used to identify roadways, or segments within a roadway, that experience a higher number of serious injuries than expected based on the traffic volume and warrant additional study and improvements. High volume roadways will most likely experience more serious crashes than a low volume roadway; however, the serious injury rate would be 33 % lower, for example, if the number of crashes on the high volume road was double and the traffic volume was triple compared to that of the low volume road.
