| 摘要： | This report documents findings from a comprehensive set of safety performance functions developed for the entire state two-lane rural highway system in Washington. The findings indicate that random parameter models and heterogeneous negative binomial models with dispersion parameter models as functions of roadside variables are effective in capturing the simultaneous impact of roadway and roadside geometrics on two-lane rural roadway safety performance. This study underscores the importance and utility of roadside data inventories in safety performance function development. |
