Nonparametric Analysis of Timely Distribution of Traffic Crash

Compared with parametric analysis method, nonparametric method is more robust and widely used. In order to make different safety policy of various kinds of time and reduce traffic crashes, this paper wisely and reasonably uses nonparametric tests models, such as Mann-Whitney, and Shapiro-Wilk, to analyze traffic crash date. After testing of normality, this paper discusses timely distributions of traffic crashes --hourly, monthly and yearly distributions of traffic crash data by nonparametric tests. So some right models for suitable timely distribution are given. Finally, analysis of related crashes data in America and China is carried out.
