Description

Intelligent traffic marking line and preparation method and application thereof Technical Field The invention relates to the technical field of traffic marking, in particular to an intelligent traffic marking and a preparation method and application thereof. Background In the context of intelligent traffic development, it is difficult for existing road infrastructure to support vehicles of the class L3 and above to achieve full automatic driving, where road marking is an important component in the road environment, which is critical for keeping lanes, guiding driving. The existing road marking only assists the lane keeping of the vehicle visually in the process of automatic driving of the vehicle, and has a single function. The existing vehicle-road cooperation (V2X) technology (such as DSRC and C-V2X) mainly depends on wireless communication, and has the problems of incomplete road section coverage, paving cost, information interaction delay and the like. There is thus a need for a highly reliable, physically binding information carrier to a road.
