2. Agenda SnowFlake Project Previous Projects Studied Areas Statistics –Vehicles –Roads –Fatalities Future work

3. SnowFlake Expansion

4. Why compare data? Look for similarities and differences in safety policies Learn from past experiences Adopt policies from each other

5. Previous Projects

6. SUNflower Developed in Europe Compare three countries –Sweden –United Kingdom –Netherlands

7. SUNflower+6 Included six countries Central –Czech Republic –Hungary –Slovenia Southern –Spain –Greece –Portugal

9. SnowFlake Comparison between a US state and a Europe country –Rhode Island –Czech Republic

14. First fatality recorded In 1869, the first road accident fatality occurred in a small town in the Irish Midlands. In 1896, the first road fatality occurred in England. In the US, in 1899 the first road fatality occurred in New York.

15. Fatalities Measure fatalities for different areas Types of measurements –Per vehicle miles traveled (VMT) –Per capita –Per motor vehicles –Per area –Per road infrastructure –Total lane length

16. Fatalities

23. Road safety features Measure specific road safety aspect Types of road safety features –Age groups –Drinking and driving –Motorcycles –Seatbelt use –Road users
