Summary
The fixed repertory grid method effectively differentiated between older and younger drivers
Area of Science:
- Psychology
- Human Factors
- Transportation Safety
Background:
- Assessing drivers' hazard perception is crucial for understanding accident risk.
- Older and younger drivers exhibit known differences in accident frequency.
Purpose of the Study:
- To evaluate various methods for assessing drivers' perception of hazards.
- To determine which techniques can differentiate between age groups with differing accident rates.
Main Methods:
- Interview methods (three types)
- Q-sort method
- Repertory grid method variants (including fixed repertory grid)
Main Results:
- Interview and Q-sort methods failed to distinguish between age groups.
- All repertory grid variants differentiated age groups, with older drivers using rating scale extremes more.
- The fixed repertory grid showed the most pronounced differences.
Conclusions:
- The fixed repertory grid is a promising technique for assessing age-related differences in hazard perception.
- Further research using this method can explore hypotheses regarding risk perception in older versus younger drivers.
