Abstract

Comparing transportation facilities (i.e., intersections and road sections) in terms of traffic accident occurrences is among the interests of most traffic safety analysts. Traditionally, traffic accidents are represented as occurrences of events per certain unit, such as time and vehicle miles; this representation is consistent with Poisson nature. The Poisson distribution is used to describe the distribution of traffic accident occurrences. The objective is to develop a test statistic to enable traffic analysts to compare traffic accident rates in various transportation facilities. The obtained test statistic is simple and requires minimal data to perform the comparison.
