Smart road marking construction method, smart road markings and autonomous driving system using the same

The present invention relates to a smart road marking construction method, a smart road marking, and an autonomous driving system using the same. To this end, the smart road marking construction method according to an embodiment of the present invention comprises: a step (S) of preparing a road marking composition by mixing a paint and a hardener; a step (S) of forming a base layer by applying the road marking composition to an upper surface of a road ; a step (S) of forming a bead layer by applying glass beads containing magnetic materials (M) to an upper surface of the base layer ; and a step (S) of allowing the resulting bead layer to be cured for a certain period of time. As a result, the lane recognition rate of autonomous vehicles by means of radar sensors can be improved, thereby addressing the limitations of conventional vision-based road markings.
