Driver Behaviour Flashcards
(36 cards)
Percentage of uk deaths as a result of RTAs
0.7%
Percentage of RTAs for 16-19 year olds
35% (Uk dept. Transport)
Rank of killer that RTA will be (predicted) in 2020
3rd biggest killer (international Red Cross)
Common theme differences of risky driving
Age, gender, speed
3 main methodologies of driver behaviour
Direct observation, stimulation and self-report
Problems with direct observation of risky driving
Investigator effects, accidents statistically infrequent, differences between vehicles
Evaluation of stimulation as a method of measuring driving
- high control e.g same setting, same amount of wine glasses
- but not ecologically valid, not risky/ lack of motivational factors like anger
Evaluation of self report as a method of measuring driver behaviour
Danger of social desirability
But Parker et al (1995) gained success with Driver Behaviour Questionnaire (DBQ)
DBQ (Parker et al,. 1995)
Self report, 6 point fixed response, 3 factors: errors, violations and lapses
An error is
A misjudgement
A violation is
A deliberate decision (to break the law/ risky driving)
A lapse is
Mistakes without serious consequences
DBQ (Parkhill et al., 1995) found high on violations were
Young, male, high annual mileage, better than average driving bias
DBQ (Parkhill et al., 1995) found high on errors were
Self aware, susceptible to mood, use motorways infrequently, considered self to be relatively unsafe and error prone
Lauton et al (1997) added which additions to the DBQ?
Ordinary violations and aggressive violations
Parker et al (1996) added which two factors to the DBQ?
Moral norm and anticipated regret
Culture and driving (Ozkan et al., 2006)
DBQ scores differ in different countries- notion of driver culture e.g. Drivers from western/northern EU score higher on ordinary violations. Southern EU higher on aggressive violations
Factors affecting crash likelihood
West et al (1996) active vs passive crashes
McMurray (1970) divorce 3x more likely to RTA bc of thinking
Demographics and crashes
Men 2x crashes (Evans, 1991)
In UK, 50% fewer women killed in RTAs
Younger= more violations
Men= violations, women= errors
Why is skills training poor at preventing crash involvement?
Overconfidence bias
Young and male drivers characteristics
Unrealisistic optimism, accept more risk, will respond more to male drivers on road, will go on Amber lights
Youth and driving style (Parker et al., 1992)
Drive faster, leave shorter distances, accept more risk, run yellow lights, perceive social approval for risky driving
Theory of Planned behaviour can apply to driving. Example
Attitude (fast is good), social expectations (friends), perceived behavioural control (bias), behaviour intention (intend to drive fast)-> risky behaviour
DeWinter and Dodou (2010) meta analysis (n= 45,000) of DBQ
Consistent evidence for questions ability to predict self reported driving accidents
