What Is the Safety Edge?
![Page 3: THE SAFETY EDGE](https://reader036.fdocuments.net/reader036/viewer/2022081507/568167ee550346895ddd5ce8/html5/thumbnails/3.jpg)
Key Message
• Saves Lives– Drop-offs are a safety challenge
• Low Cost– Safety Edge can mitigate shoulder drop-off
• Improves Durability– Safety Edge can increase pavement edge durability

33,808 U.S. Fatalities
18,087 U.S. Roadway Departure Fatalities
UNKNOWN ROADWAYDEPARTURES 2%

1 ROR Fatality Every 29 minutes
50 people will die in a roadway departure crash in the United States today.
How many related to drop-offs ?

2006 AAA Drop-Off Study(On rural paved roads with unpaved shoulders)
• Drop-off crashes were 17.7% of ROR crashes in Iowa• Drop-off crashes were 24.5% of ROR crashes in
Missouri• Drop-off crashes in Iowa were four times as likely to
be fatal as all rural crashes and twice as likely to be fatal as other rural ROR crashes
• Drop-off crashes in Missouri were twice as likely to be fatal as all rural crashes on similar roads
