Poisson model in traffic safety • Here we make the assumption of a Poisson process. (What does that imply?) • For a Poisson process, the probability of seeing exactly x events in a time interval t is P(x)= where l is the average rate of occurrence.     Suppose the crash reports show a trend of 25 crashes/year. At a 95% odds, what is the highest number of accidents we would see in a month?   if a graph was used please attach below and explain
