PSYU3399 Driver behaviour Flashcards
How did Rothengatter (1997) define Traffic Psychology?
The study of the behaviour of road users and the psychological processes underlying that behaviour. (relationship between behaviour & accidents)
How much has the % of drivers and cyclists dying on the roads changed in 2020?
-18.6 %, + 46.9%
How many lives were lost by the date of the lecture compared to this time last year?
2020: 213, 2019: 247
How does ‘vision Zero’ challenge previous road safety strategies?
Instead of punishing road users for making mistakes it aims to have everyone focusing on creating a system where those mistakes are not fatal. It takes into account human vulnerability and is forgiving of human error.
What are the cornerstones of ‘vision zero’?
Safe roads, safe speeds, safe vehicles and safe people
What interventions have brought down the road toll so far?
Compulsory seatbelts, RBT, speed cameras, graduating license scheme
What is the accident pyramid? And what does it teach us?
The same unsafe act can lead to a near miss or a fatality with a strong relationship between the frequency and other contributing factors.
What percentage deaths on roads are men?
73%
Which age group is most likely to die on the road?
17-25 year olds
What percentage of road deaths occur in regional or remote areas? What factors contribute to this?
66%. Road quality and speed.
What percentage of fatal crashes occur in speed zones of 100 km/hr or over? And why?
~ 45%.
- Speed reduces field of vision
- Impact speed increases (50 km = 3 storey drop, 100km = 12 storey drop)
- Stopping distance needed increases. Drivers underestimate the distance needed to stop
What are the 3 error types according to James Reason’s taxonomy of errors?
Slip: attentional failure (distracted)
Lapse: memory failure (forgot speed zone)
Mistake: rule & knowledge based (misapplication, wrong lane)
What are types of cognitive components that affect our capacity/ attention resources?
- Arousal: excitability/stress/fatigue
- Capacity/resources
- Selective attention: allocation of attention, road, person, mobile, map.
Why does driving in the rain affect our ability to drive safely?
Rain reduces how effective light sources are by scattering the light, reducing contrast and making objects hard to discern.
Do headlights and road markings help us see better driving on a rainy night?
Light from headlights backscatters reflecting back in eyes not on objects. And it means road markings can’t reflect light to be seen
