Intersection anti-collision intelligent signal lamp apparatus and control method thereof

The invention discloses an intersection anti-collision intelligent signal lamp apparatus. The apparatus is arranged at a corner of an intersection. The inner side of the intersection is a non-motor lane, and the outer side of the intersection is a motor lane. The apparatus includes a millimeter wave radar system, a main control unit and a signal lamp unit. The millimeter wave radar system is fixed above the non-motor lane and is intended for acquiring the come-and-go vehicle information on the non-motor lane and transmitting the vehicle information to the main control unit. The main control unit transmits a control signal to the signal lamp unit. According to the invention, the signal lamp controls a motor vehicle to turn right, which can effectively avoid accidents.
