To reduce amount of CO_2 emission and improve efficiency of commodity distribution, a highway transportation system of automatic platooning is developing by controlling closed trucks distance to reduce their large air resistance. However, driver stress intensity of automatic platooning has to be evaluated, since driver stress may occur by the closed gap distance. In the paper, bio-signal indices of surface electromyogram (sEMG) of masseter and emotional perspiration (EP) of palm are proposed to evaluate driver stress intensity of automatic platooning. In virtue of a universal driving simulator, the bio-signals of subjects were measured in virtual traffic environment of automatic platooning. By the analysis of the bio-signal indices, it is found that driver stress intensities decrease in the order of trucks distances of 4, 8, and 12 meters sequentially, and analytical result shows that the driver stress intensities of trucks distances of 4 and 8 meters in automatic platooning mode are larger than the driver stress intensities of normal driving in normal driving mode. Moreover, relations of the driver stress intensities and inverse Time-To-Collision (iTTC) in automatic platooning modes are also discussed.
