The invention relates to a traffic sign indicating device and method. The traffic sign indicating device comprises a projection light source, and the projection light source and an indicating signal switching time sequence of a traffic signal indicating lamp are kept synchronous; and the projection light source is used for projecting light to a target traffic sign associated with the traffic signal indicating lamp under the condition that the traffic signal indicating lamp is turned on, wherein a light spot formed by light projected to the target traffic sign by the projection light source is associated with an indication signal of the traffic signal indication lamp. The light rays of the projection light source are projected onto the target traffic sign, and the light spots formed by the light rays projected onto the target traffic sign by the projection light source are associated with the indication signal of the traffic signal indication lamp, so that the target traffic sign is indicated, the influence of environment and weather is avoided, pedestrians and drivers can be effectively reminded, and the identification effect of the traffic sign is improved.
本申请涉及一种交通标识指示装置和方法,该交通标识指示装置包括投射光源,投射光源与交通信号指示灯的指示信号切换时序保持同步;投射光源,用于在交通信号指示灯开启的情况下,向与交通信号指示灯关联的目标交通标识投射光线;其中,投射光源投射到目标交通标识上的光线形成的光斑与交通信号指示灯的指示信号相关联。本申请利用投射光源的光线投射到目标交通标识上且投射光源投射到目标交通标识上的光线形成的光斑与交通信号指示灯的指示信号相关联,实现对目标交通标识进行指示,避免了受环境和天气影响,可以有效地提醒到行人和驾驶员,提高交通标识的识别效果。
