When I hear people speak of using a fixed-gear on the road to prep for track racing, they usually talk about doing long work like group rides or 2 hour spinning sessions through town. This would be better done on a road bike.
You are referring to standing and rolling sprint work. I think this is best done at a track. I've seen guys do "balls out" sprints on track bikes in the city and it's scary. Dude, you can go from 0 to nearly 35mph/55kph within 100 meters.
