More vehicl icles es and more travel

• with increasing population, increasing

numbers of vehicles and increasing travel, the number of crashes on the network would be expected to increase*

• however, fatalities and serious injuries are

increasing at a faster rate than can be explained by simple traffic growth

Crashes hes vs in injuries ries

• it is important to reduce crash numbers, and we have a good understanding of the

factors which lead to crashes –

• drivers impaired, by alcohol, drugs, fatigue
• drivers distracted, by cellphones, passengers
• too fast for conditions
• the state of the road or the weather
• inexperience, etc, etc
• but, accepting that crashes are inevitable, we also need to understand the factors

which lead to fatal and serious injuries in those crashes

Crashes hes vs in injuries ries

• reducing injury severity is about mitigating energy exchange in a collision
• within the vehicle – crumple zones, seatbelts, side airbags
• with roadside features – vegetation, barriers, culverts, poles
• speed of impact – less speed, less harm
• vulnerability of user – collisions involving pedestrians, cyclists, motorcyclists
• road user incompatibility – e.g. truck vs car, car vs bicycle

If there are severity-increasing influences, deaths and injuries will increase .

Trends ds whic ich in increase ase in injur ury y sever erity ity

• crashes involving trucks are more severe
• crashes at higher speeds are more severe
• crashes involving motorcycles are more severe
• crashes involving older vehicles are more severe
• injuries in crashes when not wearing seatbelts are more severe

In 2013-2017

• 26% of car vs truck crashes resulted in death or serious injury
• 14% of car vs car crashes resulted in death or serious injury

• 1.5% of car vs car crashes resulted in death

Influenc luences es on th the road toll ll

and the severity of crashes is influenced by

• vehicle and roadside safety features
• vehicle mismatch and user vulnerability
• collision speed

crash numbers are influenced by

• vehicle kilometres travelled, increased by 10%
• licensed motorcycle numbers, increased by 11%
• average open road speed, increased 0.4 km/h*

Vehicle occupants killed not wearing seatbelts

So …

To build a safe road system free of death and serious injury

• reduce the opportunities for interactions between heavy and light vehicles,
• r between vulnerable users and other users
• improve the safety of motorcyclists (e.g. ABS, energy-absorbing roadside

features)

• have speeds that ensure serious injuries are unlikely in a collision
• every vehicle occupant wears their seatbelt, all the time

A Sa Safe Sy System em

In a safe system, people should not be seriously injured or killed as a result of someone’s mistake. The four pillars: Safe Roads and roadsides, Safe Vehicles, Safe Users, Safe Speeds The principles: people make mistakes, people are vulnerable, all parts of the system are needed, shared responsibility
