"Dear professor, Currently, we have so many road safety policies to reduce the number of casualties and deaths. The WHO guideline recommends the use of CEA for policies, measuring the outcomes in terms of death reductions or casualty reductions. The thing is we don't know which specific policy is accounted for the decrease in that number. The question is how to use CEA to analyze the effectiveness of the policy while the resulting casualty reductions etc. came from a mix of interventions. Thank you"
