Walk up and down

[Rasooljafarinejad]

What's the situation to use "walk down" or "walk up" a street?

For examole "Walk up Elm" or "Walk down the main street."

Thanks,

None whatsoever in almost all cases. In some localities, 'up' may refer to the direction of an incline, of North, or toward or away from city center.
