Theoretical maximum saturation flow rate per lane (this will allow you to do quick calculations in your head to check reasonableness at big events): 1,900 vehicles per hour per lane
So the bottom would probably be more like 25K each way. Lightrail is only about 4-8k? Meanwhile a single subway lane each way could do more than that thing on the bottom left.
What does "should" mean in this context? Wouldn't it depend on if you are trying to compare peak capacities or daily usages? I'd assume which one matters more would vary based on why you are comparing them in the first place?
Quick search gave this number:

I'm guessing you found this source: https://www.mikeontraffic.com/numbers-every-traffic-engineer-should-know/
The number from that page he should actually be using is more like this one:
(Source: I'm a former traffic engineer.)
Yup.
