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

Indicators of driving behavior

Speed

The resultant of longitudinal and lateral speed is used

Acceleration

The resultant of longitudinal and lateral acceleration is used

Lateral position

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

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
