Application of Driving Fatigue Difference in Driver Selections

Abstract

Driving on the complicated montanic road alignments, driving fatigue was caused likely by road alignments factors. In order to evaluate accurate difference of road environments on driving fatigue, the driver subjective feeling of tiredness, driving operating and psychophysiology records, and their sub-factors were adopted as evaluation factors. On the basis of group multicriteria decision making (GMDM) and fuzzy analytical hierarchy process (FFAHP) method, the driving fatigue hierarchic fuzzy evaluation model was established, and a scale method was adopted to generate the judgment matrices meeting the consistency checking firstly. Professional drivers' opinions were aggregated to form triangle fuzzy numbers with fuzzy Delphi method. Finally different influences on driving fatigue were ranked with total utility values of fuzzy numbers and the optimal alternative could be selected. An example was given, under this approach, show that the decision making process was a systematic and practical method for decision of driver selections.
