An intersection traffic auxiliary lamp comprises four independent auxiliary lamp assemblies. Each independent auxiliary lamp assembly is composed of a signal lamp pole, a control module and a reflection lamp, wherein the control module and the reflection lamp are electrically connected and packaged together and fixed to the signal lamp pole, the control module receives electrical signals of the signal lamp pole, and irradiation light rays of the reflection lamp are projected to the central area of a road. The four assemblies are independent of one another. Under the condition that four routes of traffic lights all break down, the four reflection lamps are simultaneously projected to the center of the road to form an aperture area similarly in a circular shape, and the illumination ring is considered as a simulation rotary island by adding corresponding traffic rule constraints. When the traffic lights recover, the control modules do not work, and the reflection lamps are turned off. Under the condition of the faults such as the single traffic light breakdown fault, the single reflection lamps emit light, and the warning effect is achieved.
