Technical Field

Background
The visual reference environment in the driving environment has a direct influence on the driving reaction and the driving safety of the driver. Research and investigation show that: more than 90% of traffic information of drivers is obtained visually during driving. This information constitutes the road visual reference environment. When a driver drives on a second-level or lower road, particularly in a long straight line section environment with a single road environment and no illumination at night, the driver underestimates the speed and the following distance, and the driver easily induces the involuntary acceleration behavior and misjudges the safety distance of the vehicle, thereby causing traffic accidents of overspeed driving and rear-end collision.
According to the research surface, a vehicle driver can construct a visual information reference system according to the surrounding road environment and traffic facilities in the driving process, and the distance and the driving speed of the vehicle are sensed and judged in the system. Velocity can be expressed in visual studies as the ratio of temporal frequency, which refers to the number of presentation cycles of the stimulus per second, to spatial frequency, which is the number of discontinuities per unit length of the stimulus. In essence, in such a visual information system consisting of the road environment and the transportation means, the driver is provided with the driving speed perception and the distance judgment by the periodic variation of the transportation means, i.e., the number of cycles per second of the traffic means appearing in the line of sight of the driver. The higher the time frequency, the more the number of presentation cycles of the traffic guidance facility, the faster the perception speed; the lower the temporal frequency, the fewer the number of presentation cycles of the traffic inducing facility, and the slower the perceived speed.
