1 Characteristics of Motorcycle Crashes in the U.S. Jeya Padmanaban M.S. Vitaly Eyges PhD 4 th IRTAD CONFERENCE Road safety data: collection and analysis for target setting and monitoring performances and progress Seoul, September 2009

2 Background Over the past 10 years ( ), the U.S. has seen significant: Increases in motorcycle use, Changes in motorcycle driver demographics and engine sizes, and Increases in fatal injury rates for motorcycle riders. In 2007, 5,154 motorcyclists died in vehicle crashes, an increase of 144% over the 2,116 motorcycle fatalities just 10 years earlier. 4th IRTAD Conference, Seoul, September

9 Fatal Crash Locations About 30% of all fatal motorcycle crashes occurred on grade/hill roadways. Trend seems to be towards an increasing percentage of motorcycle fatalities occurring on rural roads: ~ 50.3% on rural roads in vs. ~ 44.7% on rural roads in th IRTAD Conference, Seoul, September

14 Run Off Road Crashes FARS data ( ) 2007) shows run off road crashes account for: ~ 40% of all fatal crashes ~ 80% of all single-vehicle fatal crashes This type of crash is associated with: Young male riders Night/dark hours (8 P.M.-8 A.M.) Higher speeds (55 mph or greater) 4th IRTAD Conference, Seoul, September

15 Helmet Use and Alcohol An un helmeted rider is 40% more likely to sustain a fatal head injury than a helmeted rider. The effectiveness of helmet is 67% in reducing brain injuries. A study of 3,600 motorcycle crashes shows that helmet et use is the most SIGINIFICANT factor influencing survival. 44% of fatal riders were not using helmets; about 30% were alcohol impaired. 4th IRTAD Conference, Seoul, September

17 U.S. Crash Findings Sport motorcycles have a fatal rate that is 3 times higher than the corresponding rates for Cruisers or Touring bikes. The primary factors influencing motorcycle rider fatality are lack of helmet use, speeding, alcohol use, and rider age. Fatal crashes for Sport motorcycles are associated with young riders and risky driving behaviour, including speeding. 4th IRTAD Conference, Seoul, September

18 Other JP Research Studies Research on motorcycle crashes in other countries is also ongoing, including accident reconstruction and data collection efforts in India. In a recent fatal crash, two motorcyclists died due to head injuries after underriding the rear of a truck that had broken down on the shoulder in the dark. The most evident damage to the bike was severely bent handlebars. 4th IRTAD Conference, Seoul, September

Common Safety Issues Many safety issues in this case differ from those found significant in the U.S. study: Paved shoulders are often used as motorcycle lanes. No space to pull off safely.
