Motorcycle Related Injuries and Costs (Based on CODES Data)

1. Motorcycle Related Injuries and Costs (Based on CODES Data) Mehdi Nassirpour Xinrong Lei Dan Moore Illinois Department of Transportation Division of Traffic Safety Presented at the TRCC meeting on January 17, 2012

2. Goal • Reduce Motorcycle Crashes • What we know • What are we planning to do Division of Traffic Safety

3. Challenges (Motorcycle Fatalities and Injuries) Division of Traffic Safety

4. What We Know about Motorcycles Motorcyclists have high death rates Motorcycle deaths are increasing Motorcycles are becoming popular About 50% of motorcycle driver deaths involved in Single vehicle crashes Demographics--average age of riders is going up (37) Engine size is increasing—The higher the engine size, the higher the probability of being fatally injured Division of Traffic Safety

5. What We Know about Motorcycles Rider Characteristics differ by types of motorcycles Alcohol use is a problem among motorcyclists Supersport motorcycles have the highest overall collisions Rider safety training and education tend to reduce motorcycle related crashes (based on anecdotal information). It should be noted that the relationship between the rider training and reduction of crashes has not been established yet. Division of Traffic Safety

7. Helmet Laws Laws requiring all motorcyclists to wear a helmet are in place in 20 states and the District of Columbia (universal Helmet Law) Laws requiring only some motorcyclists to wear a helmet are in place in 27 states There is no motorcycle helmet use law in 3 states (Illinois, Iowa, and New Hampshire) Division of Traffic Safety

17. Figure 6: Percent Head Injuries by Helmet Status Total helmeted with head injury =48 Total helmeted with no head injury=402 Total Not helmeted with head injury =204 Total Not helmeted with no head injury=569 Note: the relationship between Helmet use and head injury is significant. Odd Ratio (OR) value is over 0.34 indicates that wearing helmet a protective against head injury. Division of Traffic Safety
