Provided is an LiDAR-detection-type road equipment. According to an embodiment of the present invention, the LiDAR-detection-type road equipment comprises: a safety information providing unit providing safety information, which is information on the driving of an autonomous vehicle or the safety of the road on which the autonomous vehicle travels; and a support unit having one side connected to the safety information providing unit and the other side fixed to the road or the ground around the road to support the safety information providing unit. The safety information is provided using a laser emitted from an LiDAR device provided in the autonomous vehicle. The safety information providing unit uses reflection intensity or number of point cloud (NPC), uses a color or material of which the reflection intensity is greater than or equal to first reflection intensity, or uses a shape or arrangement of which the NPC is greater than or equal to a first NPC to provide the safety information. The first reflection intensity is higher than second reflection intensity. Therefore, the LiDAR-detection-type road equipment can reduce a decline in the detection performance of the LiDAR device provided in the autonomous vehicle due to bad weather.
