Many countries carry out so called road safety reviews others call them road safety audits of existing roads. PIARC took the initiative to clarify the definitions of the pro-active procedures of: Road Safety Audits (RSA) at the project design stage, before any construction has started, screen the designs on paper for any safety issues. This is a formal process best conducted by an independent auditor. Road Safety inspections (RSI) is a systematic on-site review of an existing road by driving and walking to identify hazardous conditions, faults and deficiencies that may lead to serious accidents and to develop guidelines for both. Accident data is not required for an inspection process to be established. If accident data or other network analysis tools are available, they can be used to select the roads where the inspection should be targeted. As part of the preparatory work, background information about the road, the function of the road, the road standard and the traffic volumes should be obtained. A range of items need to be gathered for the on-site work and check lists are provided for different types of roads from the experiences around the world in terms of likely deficiencies that could be seen during an inspection. The Inspection report needs to outline the process followed; results obtained and suggest remedial action for deficiencies discovered. To assist the inspectors how to identify potential deficiencies and develop suitable strategies to prevent these, a Catalogue of Design SafetyProblems and Countermeasures has been developed. It presents a range of countermeasures can be considered, from inexpensive to costly. An evaluation of any implemented countermeasures is needed within a few years.
