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 BillionSlide6

Head-On Collisions

Most Head-On Crashes occur on 2 Lane Roadways similar to SR 46 between Columbus and Nashville

Distracted and Fatigued Driving

Crashes resulting from distraction or drowsiness (fatigue):

Are usually

run-off-road collisions, head-on collisions, or rear-end collisionsResult in higher injury and fatality ratesAre less likely to show evidence of the drivers trying to avoid the collisionSuch as skid marks, for exampleAccording to the NCHRP (National Cooperative Highway Research Program)

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)2Centerline Rumble Stripes reduce Head-On Fatal and Injury Crashes by 44% on Rural 2-lane Roads (on average)2 Slide18

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 Slide19

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)2Edge line or shoulder rumble stripes system-wide on rural highways with posted or statutory speeds of 50 mph or greater2 Slide20
