摘要：
Conducting traffic accident analysis is not an easy task. It requires an appropriate tool to be used in such analysis besides the capability of making use of this tool. One of the popular teals in this type of analysis, used in this study, is statistics. Statistical techniques provide a variety of methods to analysts in order to make decisions from data. In this paper, a likelihood ratio testing technique is used to analyze motor vehicle deaths of elderly people over eleven years. These deaths are assumed to follow Poisson Distribution. Two test statistics are developed. One is to observe any significant difference among these deaths over time. The other is to investigate the pattern of the occurrence of these deaths over the years. In addition, these two statistics are generalized to fit more application in the arena of traffic analysis.
