轮廓标反光面积对隧道行车的作用及影响关系研究

Research on the Effect of Delineators Reflective Area on Driving in the Tunnel

隧道洞内设置的轮廓标反光面积的大小,会影响驾驶员视认,使心理产生变化,影响驾驶员安全行车.本文基于驾驶员的动态视认特性,选择轮廓标反光面积设置不同的两条隧道试验段,采用实车驾车动态试验的方法,运用眼动仪采集驾驶员的瞳孔面积变化率、注视时间等参数值,通过对驾驶员视认特性的研究及驾驶员动态试验找到适合驾驶员安全行车的轮廓标反光面积.

The size of the reflective area of delineators in tunnels will affect the driver s visual recognition, which will cause psychological changes and affect the driver s safe driving. Based on the dynamic visual characteristics of the driver, this paper selects two tunnel test sections with different size of delineator reflective areas, adopts the real vehicle driving dynamic test method, and uses the eye tracker to collect the driver s pupil area change rate, gaze time and other parameters. Through the study of the driver s visual characteristics and the driver s dynamic test, this research finds the contoured reflective area suitable for the driver s safe driving.
