I would love something like Miami to be here in Jacksonville.
As a former Miamian (born and raised,) you do not
want to emulate the Miami model for transit whatsoever. The Miami "MetroFail" is poorly used, poorly maintained, and massive corruption has resulted in the line not running to either the beach or the airport.
The "People's Transportation Plan" has resulted in a lot of tax money gone "missing" and a mere, teeny-tiny link line to the airport (sort of.) And by tax money I mean billions.
The Miami Metromover, or the Miami version of the SkyWay, basically encourages people not to walk two to three blocks on actual urban streets. I went to a magnet high school in downtown Miami...the Metromover doesn't really add much to the mix, beyond the fugly pylons that hold it up. I'll give it this: it's the cheapest tourist attraction in all of Florida.
All of this corruption has resulted in a metropolitan area that needs mass transit (they are well past the tipping point for density and development,) but won't get the mass transit they need. It took 20 years for the voters to get over the MetroFail. It will take another 20 to get over the People's Transportation Plan.
Oy. Never wish for a transit system like MIAMI'S! ? ! ? !
Actually, the county I'd watch down there would be Broward. The county is generally well-run, fiscally conservative, and slowly realizing the need for better, more effective mass transit. I suspect that they'll go with a BRT system, but at least it will run to the damned airport and beach!
