Question

this road sign means image of railroad crossing sign with options: stop if traffic is approaching, three - way intersection, crossroad, railroad crossing (each with a radio button)

Explanation:

The road sign in the image clearly shows "RAILROAD CROSSING" (when the text is oriented correctly). The other options: "crossroad" is a general intersection, "three - way intersection" is a specific type of intersection, and "stop if traffic is approaching" is not what this sign means. This sign is specifically for a railroad crossing.

Answer:

railroad crossing
