Targeting high-risk groups of drivers
Adolescent drivers and elderly drivers
Proportion of drivers 65 year of age and older with a driver license – 1980-2002 (Norway)
Subgroups with functional impairments -vision
Ulleberg og Sagberg, 2003
Severe defect (extreme example)
Reduce mental workload and (consequenses) of driver error
Reduce injury if an accident occurs
Reduce mental workload and driver errors
Improve functional ability
The road infrastructure
Reduce injury for drivers, pedestrians and cyclists
Example – Avoidance of junction accidents
Main idea: lowering information processing demands (less mental workload)
Curve signal that this is an unnatural way to enter
More errors and slips/lapses?
inexperienced, driving skills are not automatized
low spare mental capacity when driving
hazards not perceived adequately
- ”Poorer” attitudes
More preferences towards risk-taking?
More social pressure towards risk-taking?
The answer seems to be ”yes” to both explanations
Experience, less errors?
Sagberg og Bjørnskau, 2003
Mild social deviance
High sensation seeking
Two ”problem groups” of young drivers
Rejection - does not elaborate the message
Reckless driving seems to be a very important part of their identity (and reflection of their personality). Difficult to change people’s lifestyle through an attitude campaign
Reducing exposure at night-time in weekends especially relevant
Focus on positiv guidance from passengers, reduce group pressure especially relevant
Slips and lapses
Automatization of the driving process
Actual driving skills
Perceived driving skills
Perceived risk of accidents
Cognitive and motoric skills
influence and individual differences
