due to many factors such as physiological, psychological, age, physical conditions and driving environment. The illusion caused by misoperation and danger. Therefore, drivers (especially novice) should understand these characteristics which are easy to cause illusions and prevent them in driving, so as to ensure driving safety.
light illusion: the light of the sun, the light of the reflected object, the headying light of the car and the strong light of the night long light light will make the driver's vision difficult to adapt for a moment, such as the bright window of the flat head, the shadow of alternately changing the trees in the sun on the roadside, the reflection of the snow in the field, the change of the light in the tunnel and so on, all of which are easy to make Motorists produce vertigo and form light illusion, resulting in operational errors.
speed illusion: the driving process is mostly based on the observed objects moving as a reference to estimate the speed, and it is not entirely dependent on the indicator of the vehicle's own speed meter. The roadside scenery is easy to overestimate the speed of vehicle, and it is easy to underestimate the speed of the car when the scene is few. It will adapt to the speed after a long time, and it is easy to misestimate the rest of the speed. Especially, it is very dangerous to underestimate the speed by mistake. This is the reason why motor vehicles enter the urban area from the suburbs.
bend illusion: the speed of a driver on a highway varies with the camber of the highway. The degree of transmission can also cause illusions. Generally, for a circular arc that does not exceed half circle, the radius of curvature that the driver often feels is always smaller than the actual radius. The shorter the arc length, the smaller the radius of curvature. When driving on a continuously turning mountain road, drivers will feel that the mountain area is easier to turn than the plain. Therefore, it is dangerous to make a sharp turn at high speed during driving.
distance illusion: for various types of vehicles on the road, the driver sometimes has the illusion of the length of the car, the distance of the train, the distance from the car, so that the distance of the meeting is not enough and the distance from the car is too close to cause the accident. Common are: the same distance, the day looks close, and at night is darker than when feeling far; front is a cart when feeling close, is a car feel distance.
Color Illusion: in the complex traffic section of urban areas, the surrounding scenery is colorful and interlaced with each other. It is easy to distract the driver's attention. Especially at night, it is easy to use the traffic light as the neon lamp; the tail light of the driving vehicle is regarded as the taillight of the driving vehicle; the brake light of the front car is misregarded as the taillight. In addition, summer wearing sunglasses can easily filter light colored objects and create illusions.
