Abstract
In order to provide a reference for managers to control traffic flow after traffic accidents, multivariate ANOVA is used to study the significant influencing factors of the impact range of the traffic accident. The impact range of the traffic accident is the length of the road extent affected by the accident. Through the real traffic accident dataset of Humboldt County, California, the distribution characteristics of the impact range of the accident were analyzed, and then the factors influencing the impact range of the accident such as weather, peak time, day/night, season, weekend and intersection were analyzed by the intersubjective effect test, and then the factors with significant influence were analyzed by the post-hoc test to further determine the significances of differences among different categories within the factors. The results show that the distribution of the impact range of the accident has the phenomenon of right skewness, and the lognormal distribution fitting effect is the best. Intersection, weather, and peak hour have significant effects on the impact range of the accident. In addition, the effects of sunny day and rainy day on the impact range of the accident are significantly different, the effects of sunny day and haze on the impact range of the accident are significantly different, the effects of cloudy day and rainy day on the impact range of the accident are significantly different.
