Abstract:
Road safety practitioners
have expressed a need to have more confidence in prioritising road
safety engineering treatments. These treatments can be generated
through standard road safety programs, black-spot assessments, community
initiation or from design and existing road safety audits.
The Road Safety Risk
Manager process has been developed to provide road safety professionals
with a tool to proactively assess road safety hazards and treatments
for the purpose of prioritising actions. The tool adopts a risk
management approach, with the ultimate aim of maximising the risk
reduction on the road network for a given budget.
AUSTROADS commissioned
ARRB Transport Research (NRS 9707 - Prioritising works arising out
of Road Safety Audits) to develop a procedure to rank the recommendations
emanating from the road safety audit of existing roads. Based on
the findings of this project the risk management approach to prioritising
road safety treatments was developed. The process is based on the
measurement of risk as a function of exposure, likelihood and severity.
Background research provides users with the ability to analyse the
hazard risk and the treatment risk reduction for over 70 different
types of deficiencies, across a variety of different road types
and severity outcomes. Following inclusion of treatment costs, the
derived risk-cost ratio forms the basis of prioritising the proposed
works. During initial testing it became evident that the process
could be applied to all road safety treatments and not just those
emanating from road safety audits.
Current developments
are focussed on the development of a user friendly computer based
system that can be used by auditors, investigators, project managers
and asset owners to meet their specific needs of risk identification,
risk management and the development of remedial treatment programs.
With a targeted approach to engineering treatments those works most
likely to maximise the reduction in road trauma can be completed.
