As vehicle reserves increase, road conditions become more congested and complex. At present, the automobile signal lamps for indicating the abnormal conditions or the driving state changes of the automobile mainly comprise a yellow light danger warning signal lamp and a red light emergency braking lamp, which can indicate various conditions such as abnormal vehicle occurrence, poor sight condition and cautious and slow driving, but the expression form is relatively single, and the different warning meanings are distinguished only by the light color, so that the comprehension ambiguity is easily caused, and when the traffic participants misunderstand, the driving safety accidents are easily caused.
Due to the lack of traffic regulation, road traffic conditions in China are people giving way for many years. The right-turning vehicles do not let pedestrians on the green light zebra crossing, the vehicles in the internal road do not let pedestrians, and the like. With the increase of the social civilization degree and the establishment of related laws and regulations, the automobile assignee has become the mainstream. However, laws and regulations urge drivers to give way to people, but most pedestrian groups still stay in the concept of giving way to people, so that the pedestrians do not realize to pass when the vehicles give way, and the two parties give way to each other without moving, thereby seriously affecting traffic efficiency. At present, the signal of making way is communicated to pedestrian's transmission to the general accessible gesture of driver and eye-catching, and general current efficiency is lower, and has the condition that other vehicles side by side robbed the line, has great potential safety hazard. Moreover, future unmanned vehicles must have the ability to actively transmit 'vehicle yield' signals to drive on roads normally, otherwise traffic confusion and accidents will result.
