An additional 6 stations at the beaches and 4 stations at UNF and St. Johns Town Center.
UNF is doing their own bike share system and received quite a few bids. They should be announcing the winning bid at the end of the month.
Infriastructure: Every city with bike share programs spent years building a network of cycling infrastructure in the forms of bike lanes, cycle tracks, and segregated paths
Bike infrastructure is certainly important. However, there are quite a few current and former Jacksonville residents who have worked for bike sharing companies and they have all looked at some very top level hypothetical plans within the In Town/Downtown neighborhoods and think it is workable. I tend to give credence to their experience.
I personally have little faith in JTA being able to properly implement a functional and successful system.
Hardly a JTA cheerleader myself, but there are a few things to consider:
a) there are few bike related organizations in the city that have the financial capability to implement such a system, so the area's only transit agency would be a natural fit
b) JTA's new leadership is interested (the old leadership wouldn't even blink an eye at the suggestion)
c) although private sponsors subsidize most systems nationwide, virtually no private sponsors will fund a feasability study... and an organization like JTA wouldnt necessarily have to do a feasability study (look at Tampa's system for example, they didnt do an expensive feasability study, they just put an RFP out and see who was interested- and apparently many were).
d) even though some City Council members are interested (important b/c you need to have public right of way access for bike share stations), JTA already has dedicated right of way access so you are again skipping a step.
e) I'm not 100% convinced a bike share system would work (I have reservations that aren't completely out of line with your own)... but there is never a 'perfect' time for anything in life. Sometimes, you have to get your hands dirty... nothing will ever change otherwise.
If Tampa can do it, why not Jacksonville?
