I like to see something like this.
Old Dutch ANWB (Algemene Nederlandse Wielrijders Bond) road signs.
Just a pole with 1 or 2 arrows, 3 not needed but should be nice..

Top is a wheel with a wing, any wheel/wing will do. If none available, then without is also fine.
Of course the NAMES, towns, destinations must be adjustable, by settings or script.
If not possible, only one direction will be fine too.
(I write this in English, my German reading is fine, but writing not).
Danke sehr!
