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

A smart road marking construction method comprising:

• a step (S10) of preparing a road marking composition by mixing a paint and a hardener;
• a step (S20) of forming a base layer 10 by applying the road marking composition to an upper surface of a road 1;
• a step (S30) of forming a bead layer 20 by applying glass beads 21 to an upper surface of the base layer 10;
• a step (S40) of allowing the resulting bead layer to be cured for a certain period of time;
• a step (S50) of forming an insertion hole 30 by grinding the bead layer 20 and the base layer 10 to a predetermined diameter and depth;
• a step (S60) of applying an adhesive 31 to the inside of the insertion hole 30;
• and
• a step (S70) of inserting a magnetic marker 40 into the insertion hole 30.

An autonomous driving system using a smart road marking comprising:

• a smart road marking 100 including a magnetic material (M) or a magnetic marker 40;
• a radar sensor 200 that is mounted on a vehicle to recognize road marking information including the location from the smart road marking 100;
• and
• a driving assistance device 300 that controls the vehicle's movement based on the road marking information recognized by the radar sensor 200.
