Also, I would say that measuring growth as a percentage could be a little misleading. Take SLC for instance. They grew only 19%, but, if I'm doing the math right, that's around 9,000 riders. Growth is good, but I wouldn't say that this train has "arrived" just yet.
I'd take them on a case by case basis. Salt Lake City has 35 miles of LRT track that has been incrementally expanded over the last decade, as well as benefited from commuter rail and BRT projects added over the years, feeding riders into it. So while a 9,000 jump in riders is great, they also invested hundreds of millions in expanding their fixed transit spine network, which is leading to the new growth as more and more areas of that metro become accessible to it. Expect more Salt Lake City jumps this year once more commuter rail, streetcar, and LRT corridor expansions are completed.
Nevertheless, the Skyway's jump is highly impressive because we've witnessed a +100% increase without adding a dime to expand a short 2.5 mile line that hasn't averaged more than 3,000 over the previous two decades. If we actually invested in our mass transit system we'd see similar increases as Salt Lake City, as reliable mass transit becomes accessible to more and more areas of the city.
At the end of the day, I believe the Skyway's recent growth by simply changing how it is utilized, really does illustrate the potential of mass transit in Jacksonville, assuming we don't continue attempts to hold it back. All of this kind of goes against the argument of those saying mass transit can't work here in Jacksonville or that the Skyway is a complete waste. It probably would be just as effective as originally conceived if we work on following out the original concept of feeding it with a connected rapid transit system (sorry guys, our BRT plan is not real rapid transit).
