Here's link to an interesting StreetFilms video about how "Complete Streets" principles are revitalizing New York City. On-street parked cars buffer the bike lanes, which the City painted green. (The Federal Highway Administration has now approved green bike lanes. They should become more common.) The City installed the bike lanes without reducing the number of lanes by narrowing lane width from 12 feet. You'll find ideas in the video applicable to less dense areas, including Central Florida.
