• Abstract:
  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.
