AB - The purpose of this study is to develop traffic accident models based on spatial effects and traffic accident data characteristics. Statistical models are constructed with the number of traffic injuries observed from 277 segments of interstate highway I-5 in Washington for 9 years from 1999 to 2007 as a response variable.
A significance test for Moran’s Index is conducted to determine whether or not spatial autocorrelation exists among the segments. Spatial zero Inflated model and spatial hurdle model are used to reflect excessive zeros in the response variable as well as spatial effects. Those models are found to be appropriate to handle the data according to DIC. Therefore, we propose these models as an optimal traffic accident model, which allows us to determine the effect of major factors of traffic accidents by investigating the influence of each explanatory variable in the models.
