Traffic Fatalities

2012 Statistics from the CDC
(Centers for Disease Control):



For ages 5–24 Motor Vehicle Crashes are the
#1 Cause of Injury Deaths
For ages 25-65+ Motor Vehicle Crashes are
the #2 Cause of Injury Deaths
In 2012 2.5 Million persons were treated for a
traffic injury at a cost of $80 Billion

Distracted and Fatigued Driving

Crashes resulting from distraction or
drowsiness (fatigue):



Are usually run-off-road collisions, head-on
collisions, or rear-end collisions
Result in higher injury and fatality rates
Are less likely to show evidence of the drivers
trying to avoid the collision

Such as skid marks, for example

Safety Benefits of Rumble Stripes

Peer-Reviewed Traffic Safety Studies


Shoulder Rumble Strips (e.g. Edge Line Rumble
Stripes) reduce Run-Off-Road Fatal and Injury
Crashes by 36% on Rural 2-lane Roads (on
average)2
Centerline Rumble Stripes reduce Head-On Fatal
and Injury Crashes by 44% on Rural 2-lane Roads
(on average)2
Rumble Stripe Noise Considerations



Admittedly, noise levels near the roadway
can sometimes be objectionable.
However, the lives that can be saved by
rumble stripes must be balanced against
this drawback.
According to a 2007 study, 13% of the peak rumble
stripe noise levels were above the highest noise level
measured for a commercial vehicle driving along the
roadway (not hitting the rumble stripes)3
FHWA Guidance

FHWA recommends and provides funding
for the following INDOT safety programs:


Centerline rumble stripes system-wide on undivided
rural roads with posted speeds of 50 mph or
greater (where the sum of the lane and shoulder
width for each travel direction is at least 14 feet)2
Edge line or shoulder rumble stripes system-wide
on rural highways with posted or statutory speeds
of 50 mph or greater2
