Description
Technical Field
The invention relates to the field of traffic facilities, in particular to a safe and intelligent traffic light warning device.
Background
With the development of economy in recent years, the dream that each family has one or more automobiles is nearly realized, and with the increase of the automobile keeping amount in China, the road construction in various places is also carried out in a fierce manner. However, road construction in various places can not keep pace with the development speed of automobiles, so that various traffic illegal behaviors on roads are frequently rare, particularly red light running at a crossroad occurs frequently, the occurrence rate of traffic accidents at the crossroad is high, particularly the red light running phenomenon of electric bicycles and electric automobiles is prominent, and how to enable vehicles normally running in a green light direction to know information of the approaching of the vehicles in the red light direction in time is the most effective means for effectively reducing the traffic accidents.
The traffic light is the most basic method for effectively reducing traffic accidents at crossroads, but drivers of electric bicycles and electric vehicles are not easily restricted by the traffic light because of no driving license, so that the phenomenon of running the traffic light often occurs, on one hand, the drivers require traffic polices to educate the traffic knowledge of the drivers, and on the other hand, the drivers also adopt technical means to reduce the traffic accidents caused by running the red light. The existing technology in the prior stage is difficult to effectively reduce the traffic accidents, for example, automatic lifting separation columns are installed in some cities, when red lights are lighted, the automatic lifting separation columns capable of preventing the red lights from running can be automatically lifted, and vehicles are prevented from moving forwards, but the device is easy to damage, the phenomenon of inflexible operation is often caused, more traffic accidents are caused on the reverse side, and particularly, the traffic accidents are easily caused when the rear vehicles do not find that the front automatic lifting separation columns are lifted. In addition, some cities design red light running water spraying systems, but the effect is also very unsatisfactory, because when the water smoke descends suddenly at the intersection, the illusion of the driver can be caused, and the accident is caused, and what is more, the water smoke descends suddenly on the glass, so that the driver cannot see the front condition suddenly, and the accident is caused. I design's a safe intelligent traffic lights warning device just can see the red light of running suggestion condition when seeing the traffic lights through installation suggestion device beside the traffic lights, can effectively conveniently and reduce the traffic accident that the red light of running caused safely.
