Re: capitalize the first letter
I would expect to see the words on those signposts/signboards either all in capitals (PLAYGROUND/SWIMMING POOL) or with the the first letter of each word capitalised (Playground/Gymnasium). The word should be treated as if it is the first word of a sentence and should therefore be capitalised. In the case of a two-word name, capitalise the first letter of each word for consistency (Swimming Pool).
