For the segments of the street "Národní", it would be useful to add tag alt_name="Národní třída". (Common name of the street; the word "třída" means "big street", "avenue".)

By the way, is there a way to associate the street segments together so that searching for the street's name returns the street as a whole? The segments are: 7654224, 299273175, 299273172, 299273174, 4319511, 141509441. (That's the segments I found.)
