Zwickau University has developed a new multi-stage methodology for the complex design process of upgrading rural roads.


Using virtual journeys (automatically defined driver profiles or simulation using driving simulators), expected driving behaviour can be assessed using characteristic feature graphs and the derived quantitative parameters.

Key Findings:

  • The results presented have clearly demonstrated that driving behaviour can be reliably assessed during the design process by means of virtual driving sessions.
  • A relative comparison between the existing and upgraded road is possible with the help of the assessment parameters developed here. Maximum or minimum figures for the individual assessment parameters still have to be determined as part of a validation process.
  • If individual design parameters deviate from the standard values, the driving behaviour graphs and the associated quantitative assessment parameters must be drawn on as the professional basis for approving any exceptions.
  • The new kind of methodology developed forms a solid foundation for developing a standard procedure for the design process for modification and upgrading work.
