Abstract

The limited funds available for minor safety works must be spent on the right sites and consequently the identification of  those sites and appropriate treatments cannot be over  emphasised.  This can be a real challenge on a large rural  network where several sites compete for limited funds.  This  paper presents a framework that may assist in preparing road  safety action plans for rural road networks taking a holistic  approach encompassing educational, enforcement and  engineering measures.  A top-down framework consisting of  four steps with macro level analysis at the top and detailed  analysis at the bottom is presented.  The macro level analysis  gives a strategic overview of the road safety trend, crash  pattern, and crash characteristics over the network.  The meso  level analysis identifies the spread of crashes and contributing  factors over the network.  The findings from macro and meso  level analyses may assist in designing educational and  enforcement measures.  The micro level analysis identifies  black and white spots by distinguishing sites with an over- and  under-representation of crashes, respectively.  Finally, the  detailed analysis assists in the selection of appropriate  treatment.  The framework is being applied to a road network of  about 844 kilometres in length and preliminary results are  presented.
