"Isn't it possible that during the first year many riders decided to try SBS because of all the hype so ridership increased during the first year."
Yes, but those people would be insignificant in number to matter.

"But during the second year they realized they really weren't saving time or machines started to break down more often causing needless hassle or they received summonses unfairly and decide to resume their former traffic patterns during the second year so ridership declined. Or perhaps enforcement declined during the second year and fare evasion increased leading to lower ridership numbers but not really reduced ridership."
LOL. And the aliens could also tell them not to ride SBS in 2014. THAT MUST BE IT! but wait...ridership went down systemwide, so that probably isn't it.

"All those are distinct possibilities that would be reflected in second year statistics not the first."
All of those distinct possibilities. Yeah, distinctly absurd.

"THERE IS NO REASON THE BELIEVE THAT FIRST YEAR STATISTICS TELL THE ENTIRE STORY ABOUT THE EFFCTIVENESS OF SBS."
Actually there is. It is called isolating a variable. In most cases, transit in the area did not substantially change outside of the SBS improvements. Therefore you can look at before and after the changes and see what they did. You are correct with regards to some of the lines- The M60 surely DID have other changes affecting it, as LGA had a new route added which serves much of the same market as the M60 did.

"There are far too many variables to determine success entirely from the first year statistics."
Certainly, but it tells you SOMETHING. Comparing ridership of two years AFTER the changes tells you ABSOLUTELY NOTHING about the changes.

"Also since B44 ridership declined during the first year, does that mean it didn't work and should be discontinued?"
No. Ridership is by no means the only measure of success.

"Or should changes be attempted to try to make it successful?"
YES!, but there is no reason to call it unsuccessful. Changes should always be considered to make it MORE successful.

"I would think the latter."
Of course!
" But if we made changes, second and third year statistics would be meaningless according to you because ONLY THE FIRST YEAR MATTERS AND NOTHING ELSE."
NO. The first year would still be ALL THAT MATTERS with regards to the first set of changes. The second to third year would then be ALL THAT MATTERS with regards to the second set of changes.

You really need to learn the concept of ISOLATING VARIABLES.
