The invention relates to a road lane line coding design and recognition method based on a laser radar, and belongs to the technical field of intelligent traffic infrastructures and automatic driving assistance systems. A five-bit binary coding mode is set, and basic information required by accurate positioning is covered; a specific reflectivity coding rule is embedded in a lane line, and a laser radar is used for identifying the codes, so that the technical problem that camera identification is greatly influenced by the environment is solved; the positioning information is carried by improving the material attributes of the lane line, visual confusion with the road marking is avoided, meanwhile, the requirement for changing the appearance of the existing road marking is avoided, and the road traffic specifications are met; and the construction and maintenance process is simple, and the maintenance cost of infrastructures is reduced. 本发明涉及一种基于激光雷达的道路车道线编码设计与识别方法，属于智能交通基础设施和自动驾驶辅助系统技术领域，本发明设置了五位二进制编码模式，涵盖精确定位所
