Safety sustainability
• Traffic safety in the U.S.: Re-examining majoropportunities
• Mechanisms involved in the recent large reductions inthe U.S. road fatalities
• A road-safety upside of the current economic downturn
• The future of personal transportation the megacities ofthe world
• Road safety in China: Challenges and opportunities
• Road safety in India: Challenges and opportunities
• Road safety in Brazil: Challenges and opportunities
Common elements
• Lead authors from the respective countries
(Wei Zhang, Dinesh Mohan, Eduardo Vasconcellos)
• Identification of the largest “cubes” of total harm
• Identification of effective countermeasures for each
“cubes” that reduce the exposure, crash risk, or crash

Conclusion
Major safety improvements could be
made worldwide by using targeted
countermeasures based on scientific,
system-wide understanding of the
mechanisms that contribute to the
occurrence of large components of the
overall problem in each country
