Abstract
A method, controlling device, and system for simulating a generation of black ice on a road including steps of: (a) in response to an ambient atmosphere being determined as in a (1-1)-st state, changing the ambient atmosphere to be in a (1-2)-nd state by referring to a (1-1)-st simulation variable corresponding to a temperature of the ambient atmosphere and a (1-2)-nd simulation variable corresponding to a humidity of the ambient atmosphere; and (ii) in response to a road specimen being determined as in a (2-1)-st state, changing the road specimen to be in a (2-2)-nd state by referring to a (2-1)-st simulation variable corresponding to a temperature of the road specimen and a (2-2)-nd simulation variable corresponding to a residual precipitation; (b) applying a triggering action; and (c) determining whether the black ice is generated on the road specimen.
