The automobile brings great convenience to people in life, and meanwhile, certain burden is caused to roads, and traffic accidents frequently occur. The global status report of road safety states that road traffic injuries are the eighth cause of death worldwide, 120 thousands of people die of traffic accidents every year in the world, and 2000 to 5000 thousands of people suffer non-fatal injuries.

The reasons for traffic accidents include drivers' speeding, lack of attention to the state of the vehicle in front, negligence in driving, and illegal driving. According to the automobile accident data, the following data are shown: over 80% of accidents are caused by drivers' untimely response or misjudgment in the face of an emergency. Studies by Daimler-Cleisler indicate that a 90% collision event can be avoided if the driver has an additional warning time of 1 s. However, the reaction time and the visual field range of people are limited, and the accident rate cannot be reduced comprehensively and greatly only in the aspect of improving the quality of drivers.
