Improving both the visual and the experience
I decided that I will use rectangular monolith like shapes for my signs instead of smaller signs that are now suspended above the ground on poles. I chose a dark colour for the background of my graphics, which is why the signs would be made of a material in this dark grey colour. When it comes to the measurements I did my first sign in the hight of 192 cm bringing the map, that would be on that sign to about the eye level of an average person. The width of the panel is 96 cm which is half of the height. I based my other panels on this keeping the proportions in mind. The middle panel on the grid is made using the same proportions of height and width (2:1), while the leftmost panel is very narrow but still remains within the set proportions of the signs.
