How many people die in australia due to road crashes?
4 die
550 injuries
48000 crashes
Is the road traffic injury problem man made problem?
Yes
What are the desired transport outcomes?
- Safer Transport to support safer communities
- Efficient and effective transport to support industry competitiveness
- Environmental management to support environmental conservation
- accessibility to promote equity and social cohesion
What is the ranking for vulnerability of injury
Higher to Lower
Pedestrians
Bicyclists
Motorcyclists
Car Occupants
Which states has the highest road toll?
Sweden
NSW
QLD
Victoria
From highest to lowest
What is externality?
Transaction is an impact on a party that is not directly involved in the transaction
Something that impacts others (crash costs whole community not just individual)
What percentage of human factors contribute to road crashes?
95% for human
What is the biggest factor of injury?
Velocity/Speed
What is Haddons Matrix?
a Matrix which provides an analysis framework
Phases: Before Crash, During crash, After crash
Factors : Human, vehicle, road
How is cost of crashes calculated?
- Human Capital
2. Willingness to pay
What are the components to human capital cost?
- Health, injury costs
- Expenses of death
- Vehicle and property damange
- emergency services
- legal costs
- loss of future earnigns
costs QLD $2.5M
What are the components of willingness to pay
How much youre willing to pay to avoid being killed
- Estimating value individuals attach to human life
What is vision zero?
Cannot build a new piece of infrastructure that could kill someone
To fund this:
Fines, restrictions, higher costs
What is the road safety strategy?
Exposure control Crash Prevention Injury Control Behaviour Post injury
What is the safety engineering mindset?
Mobility - a function of traffic safety
Crashes have multiple causes
Systematic analysis of reliable data
How are users match to systems?
Influencing opportunity for a crash to occur,
Influencing probability of a crash occurring
controlling the process of energy exchange
What are the principles for safe design?
Match road design to purpose
Make separated provisions for incompatible forms
Minimise conflict points & reduce probability of collision
Manage for crash severity
Speed Management
What is the decision making process?
Optimum time to ensure mobility with safety is at the time of original design
Adopt a systematic road safety audit process
crash and injury data sets are used to identify black spot or black lengths
Community and politicians focus on absolute numbers
What are the ways data is collected?
0: pedestrians
1: Intersections
2: Vehicle Opposite
3: Vehicle Same
4: Manoeuvring
5: Overtaking
6: On Path
7: Off Path Straight
8: Off Path Curve
9: Pass and Misc
Is decision making depend on the quality of the data?
Yes
What is the current trend for road deaths?
decreasing
Sweden lowest
Australia at or just below OECD median
becoming harder to improve
What information is required?
Comprehensive Objective Consistent Accurate Accessible Efficient Accurate Locations Sequence of events Analyse by factors Cost Consequence Rank site
What are the main sources of data?
- Police
- Hospital Admin
- Insurance
- Coroner
What are some other data that is required for safety?
- Demographic
- traffic volume
- seatbelt usage
- road length
What are the limitations?
Under reporitng Bais Errors Definitions Delay Statistics
How is the data used?
Performance indicators and benchmarking
Development of countermeasures
Countermeasure targeting
