Traffic fatalities and sporting events. The relationship between close sporting events and game-day traffic fatalities was investigated in the Journal of Consumer Research

(Dec. 2011). The researchers found that closer football and basketball games are associated with more traffic fatalities.

The methodology used by the researchers involved modeling the traffic fatality count for a particular game as a Poisson random variable. For games played at the winner’s location (home court or home field), the mean number of traffic fatalities was .5. Use this information to find the probability that at least 3 game-day traffic fatalities will occur at the winning team’s location.
