What are these signs that are on the crosswalk poles?

  1. Tells you the location of the water shut off valves. (Yellow signs are the same but for gas, red are for underfloor hydrants)

    Top sign is for a pipe with a diameter of 200 ~~cm!~~ mm. The valve is located 1 meter away from the sign (from the sign to the direction you are standing), and 2.5 meters perpendicular to the right. At that point will be a cover in the pavement.

    Edit: Should read what I link to. Btw: 200 mm are 0.3692 Bernere Ellen.
