For example, lanes are marked with a double yellow solid line on the center line of the road to separate the driving directions of vehicles from each other (center line), and the lanes and lanes for driving vehicles are separated, but the direction of change of course between lanes is different. The restricted section is marked with a white solid line as the boundary (general driving lane), or the section where course change and entry between lanes is allowed is marked with a white dotted line (overtaking lane). Furthermore, the crosswalk is painted and marked as an area where pedestrians can cross the road, but it is painted and marked with a wider width than the general driving lane.

In this way, in the work of painting lanes on the road surface, a lane construction device installed in a vehicle and manufactured to automatically spray and spray the paint along the driving surface on which the vehicle moves is used for construction.
