Research On Physiologic And Psychological Characteristics Of Drivers In Plateau Road Based On Driving Aptitude Test

Due to the plateau environment is different from the plain region, Therefore, conditions are relatively complex, Its effect on the driver is very significant, So the study high altitude environment driver's driving characteristics, to improve Plateau highway Road safety and to prevent traffic accidents Have important Significance.In this paper, G314 for example, by introducing the plateau region special geographical environment and climate, in-depth analysis plateau special environment the impact of psychological and physiologic Characteristics on the drivers; by referring to a large number ofdomestic and foreign literature, a brief introduction to the concept of the driver's suitability, briefly describe the item of the driver suitability detection and the detection system, analyzed Impact driver driving characteristics of physiological and psychological factors; In order to effectively characterize the psychological and physiological changes of the plateau highway drivers, Taking the dynamic visual acuity, velocity estimation, selection reaction, reaction error number and disposal judgment as the evaluation index and use the test equipment for static detection.Based on detection data, separately analyzed of different altitude, continuous driving time and the change rule of each Index, and calculated the correlation degree between the factors and the evaluation indicators, used principal component analysis to establish evaluation model for plateau highway drivers driving characteristics, by extracting principal components, reduced the complexity of the problem, and extracted the three principal components use evaluation model.According to the comprehensive evaluation model obtained the E score of different altitude drivers, the model is divided into different thresholds range accuracy as the set threshold range of conditions, the final [0?0.1] is set to the threshold range, so accuracy of 80% is distinguished by the suitability of different sea drivers, thus discrimination in the altitude environment accident tendency driver provide new ideas.
