Abstract:
This paper randomly selects 32 drivers to carry out contrast experiments with different color obstacles and different distance cognitions. By analyzing the space distances of red and green obstacles under different velocities and depth distances in the direction of running, this paper gets the distance cognition values, analyzes the cognition values and studies the quantitative laws of cognition to different color obstacles, and sets up the mathematics models and compares the quantitative differences between red and green obstacles. The experimental results show that the cognitive values continuously decrease with the speed increasing, and there is negative expression relation between them; the colors have no influence on variation tendency, but cognition values of obstacles with cold color is larger than warm one. 6 tabs, 4 figs, 9 refs.
