Objective
We aim to investigate the driving behavior of different drivers in and nearby a curve using data from a fixed-based driving simulator in order to: Identify the best drivers within the sample To gain insight into the most problematic behavior of each driver
Methodology: data collection and analysis
Real-world simulator image
The road width is 2.8m and the posted speed limit is 70km/hMethodology: participants and simulator
Participants
38 volunteers 4 excluded: 2 simulator sickness, 2 miss values 34 participants in dataset; 23 men, 11 women Age: 18-54 mean age 26.32; SD 10.47
Driving simulator
Fixed-base STISIM M400 with 180° parabollic screen

After curve
Hierarchically structured driving performance indicators
Multiple Layer Data Envelopment Analysis- MLDEA
- The focus of DEA is on individual
- By solving the model, the best possible indicator weights are
determined
- An index score between zero and one is obtained for each
driver, with a higher value indicating a better performance
- Take into account the layered hierarchy of indicators that
- ften exist in reality
Results and discussion
Index scores and drivers ranking Weight allocation and required improvement priorities Comparison of typical drivers in terms of driving performance parameters

Conclusion The application of this methodology to simulator data is innovative
and will: Distinguish the best drivers Gain insight into the most problematic behavior of each driver
Future research
Assessment with respect to older drivers Focus on young novice drivers
