The road crew is stopping the traffic.

I looked up the answers.com and it told me that "the road crew" are the technicians who travel on tour with musicians and who handle every part of the production except actually playing the music.

But who do the road crew mean here? I guess they must be like some people working on a road construction. Please advise.

Right.
The "road crews" you are describing about the bands are more commonly called "roadies" (in the U.S.)

The road crews who work on the roads are never called that ("roadies."). You can also hear them called just "work crews" (and the fact that they are working on the road tells you what kind of work).

Grammar GeekThe road crews who work on the roads are never called that.

Beg to differ here:

They're never called roadies. That's the term for the crew that travels with the bands.
