I think it's far more likely that north Minneapolis bus riders will transfer from Target Field or Royalston Station.
There's no doubt a lot of Northsiders will use Royalston. Maybe more than Van White.
I've never been able to find any plans for transit on Van White, and they don't appear to be in the DEIS, LPA or AA docs (neither, for that matter, is a rerouting of the 19 to terminate at the Penn Ave station). That gives us the freedom to speculate: what would a Van White feeder bus look like? Would it be a branch of the 5, the 9, or the 19? Personally, I would favor a new all-day route that runs on 55 from the Plymouth industrial districts, then goes down Van White to Dunwoody and up Hennepin to terminate downtown (or as an overly-long extension of the 61 maybe). But I can't think of an alternative that wouldn't inconvenience those riders continuing downtown in order to detour to the Van White station. Can you?
But the result was a situations where stations in predominantly white areas were 1/2 mile apart while those in historic communities of color with a high proportion of transit-dependent people were a mile apart.
In St Paul the only stations outside Downtown that were originally a 1/2 mile apart were Fairview and Snelling, and I'd say that calling that area predominantly white ignores a substantial minority (mostly African-American) presence. In Minneapolis the stations were closer together but clearly that is due to the density and student presence.
