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
