Road Safety Interactive Mapping Tool
A Safe System Approach to Road
Safety
• International and national endorsed
approach to manage road safety
• National:
o National Road Safety Strategy
2011 – 2020
o Queensland Road Safety Strategy
o Austroads Guides to Road Safety
2
Safe System Framework - Australia
• Road users will make
mistakes
• Humans are physically
vulnerable
• Road users should not be
seriously injured
• A system approach – road,
vehicle, road user & speed
• Infrastructure that takes
account of these errors and
vulnerabilities is required
(shared responsibility)

NetRisk
What is NetRisk
• Developed by ARRB in collaboration with the QLD
Roads Alliance
• NetRisk pro-actively identifies hazards and safety
issues across a road network considering likelihood and
severity.
• The process measures the inherent road safety risk
that is built-in to the road
‘much greater emphasis needs to be placed on initiatives that
improve the inherent safety of the road transport system.’
NRSS 2011 - 2020

Why not just treat crash sites
• Blackspots are becoming more dispersed and harder to treat
o only 30% of fatal crashes occur at black spots
o over half of fatal crashes occur in sections with no prior 5-year
reported fatal crash history.
(Based on Vic and NZ data - Roper, P & Turner, B 2008)
• The “Safe System” approach and duty of care demand more
• Communities do not want to wait for trauma before action is taken
• Knowledge of crash risks has improved significantly, facilitating
comprehensive proactive risk-based analysis
• One part of an overall engineering, education
and enforcement strategy.

Purpose of NetRisk
NetRisk’s two main purposes:
1. Assist the road authority in meeting its duty of care in
relation to legal responsibilities.
2. A road safety assessment tool to assist road
authorities target investment; and

Wide Bay Burnett RRG Risk Map - Mid
blocks
Facts
• 1333 km of roads
assessed
• Risk score range:
0.5 – 29.0
• 316 km (24%) high
risk sections (risk
score >=10.0)

NetRisk: Typical high risk site/safety
issues
Safety issues
• Unforgiving roadside
condition (trees)
• Poor delineation
• Sharp curve
• Narrow carriageway width
• Restricted sight distance
• Poor overtaking opportunities

NetRisk limitations
• Focuses on all road environment
deficiencies
• Cost prohibitive for any govt agency to
meet NetRisk standards
• Is expensive to repeat - $2M statewide in
2009
• Never intended to be a stand alone
analysis tool
Road Safety Interactive Mapping
Tool
RSIM Tool
• A tool to focus road safety efforts
• An amalgamation of data layers (WebCrash and
NetRisk) to:
o Reduce expenditure on perceived risks
o Avoids focussing on all of the issues
o Evidence based decision making
o Defend expenditure decisions
o Reduce political interference

CRASH DATA ISSUES
• The accuracy in recording data
• Crashes not reported






Unlicensed
Unregistered
Drink drivers
Cyclists – minor
Pedestrians – minor
Off-roadway
• Many layers - risk exposure, numbers, emerging
• Hospital & Emergency Services data – access
• Not utilised - Perception of road safety problem
vs Evidence
