1. Traffic. Marietta Traffic Authority is concerned about the repeated accidents at the intersection of Canton and Piedmont Roads. Bayes-inclined city-engineer would like to estimate the accident rate, even better, find a credible set. A well known model for modeling the number of road accidents in a particular loca- tion/time window is the Poisson distribution. Assume that X represents the number of accidents in a 3 month period at the intersection od Canton and Piedmont Roads. Figure 1: The Intersection od Canton and Piedmont Roads, Marietta, East Cobb, GA. Assume that [X|] ~ Poi(0). Nothing is known a priori about 0, so it is reasonable to assume the Jeffreys' prior T (0 ) = -1(0
