Abstract
In a designing method for setting a specification of an individual-piece magnetic marker to be laid on a road surface, a specification of the magnetic marker is appropriately set based on a correlation coefficient between a first distribution of strengths of magnetism in a forwarding direction acting on a position at a minimum attachment height in a range of attachment heights of the magnetic sensor assumed in respective vehicles and a second distribution representing a distribution of strengths of magnetism in the forwarding direction acting on the position at the minimum attachment height when magnetism is assumed to be generated from a one-point magnetism generation source.
