Experimental Research on Driver Fatigue Based on SOFM

An evaluation model of driver fatigue state was constructed based on the self-organizing feature map (SOFM), in which reaction time, steering angle and vehicle trajectory were considered. 10 males in the same age phrase were recruited to drive under monotonous conditions on self-made driving simulator. The statistic analysis of the test data showed that the three indexes mentioned above were correlated with the subjective evaluation which was performed by the experts according to the recorded videos distinctly. From the experimental results, it was found that the fatigue levels classified by SOFM evaluation model were in accordance with subjective evaluation, and SOFM evaluation model could recognize the levels of driver fatigue state automatically and accurately.
