Please forgive me for being a spaz. The industry runs away from admitting this to keep the $$$$$$$$$$ flowing.
So Charlotte goes from 5 million trips a year to 5 million.
Let's walk through what we should be seeing.
For example, let's be conservative on job / FTE estimates in those millions and millions of sq ft added for commercial. And let's just assume that no housing unit added has more than 1 person living in it. So maybe we're looking at 15,000 more people on the corridor.
If 1,000 of them - 1/15th - used transit twice a day, one round-trip, 200 days a year, that would be 400,000 _additional_ trips per year. In fact, anyone working full-time making that daily round trip would lead to traveling 235 - 265 days a year ( vacation, 4 10 hr days, etc ).
So a mere 1/15th of the people ADDED to places right up by the light rail stations making a roundtrip 250 times a year means that LYNX would have seen it's ridership go from 5 million / year to 5 1/2 million a year.
Remember the core claim is that all this construction is happening because people will pay top dollar to use the train + bus.
If 20% of them did this, that would be an additional million and a half trips a year.
Yet LYNX went from 5 million a year to 5 million trips a year --- FLAT -- for that decade.
And they're not eschewing the tram for the bus. Total ridership for CATs went from ~26M in 2009 to ~25M in 2017.
What's that you say? 2017 ridership was down because of a fluke. Well, 2016 was ~26M and 2010 was ~26M .... so ya, there's some year to fluctuation. But total ridership for Charlotte Area Transit ( CAT ) is flat too.
All those new residents + all those new office + retails jobs being added 1/4, 1/2 mile by all fo the LRT stops may be filling up with people, but those people ain't taking transit any more or any less than they were before the LYNX tram was built and those ~10K housing units + ~2Msqft commercial were built.
