  1. THE SAFETY EDGE

  2. What Is the Safety Edge?

  3. 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

  4. Basic Principle Conventional Paving Paving with Safety Edge Safety Edge Installation: Georgia

  5. The Safety Edge: Purpose and Need Safety Edge Installation: Iowa

  6. 2009 Fatal Crashes (Based on FARS) 18,087 U.S. Roadway Departure Fatalities UNKNOWN ROADWAYDEPARTURES 2% 33,808 U.S. Fatalities

  7. 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 ?

  8. 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
