Underground Parking Pictogram
Underground parking pictogram which could be used by default did not exist before recently. Now, it does.
Marking an underground parking (for example, on a map of the area or residential building) is the main application for this pictogram.
The sign grapheme is easily adjustable for any icon set.
The arrow on the pictogram imposes some restrictions: any ambiguity in the parking location should be avoided when using this pictogram.
