Ignoring the effect of heavy vehicles and assuming a free flow speed of 70, the federal highway authority’s numbers would be 2400 vehicles per lane or 55k vehicles per hour. Assuming an average occupancy of 1.5 people per vehicle, that’s nearly 83k.
Although 83k people per hour is 41.5k people per rail track. Assuming a 360 person train like the Bombardier BiLevel Coach, that’s only 115 train cars per hour per track. If each train has 11 cars, that’s 10 trains per hour or a train every 6 min. Not really that unreasonable, and the tracks will look mostly empty unlike that monstrosity of a road.
Yeah.
I think I count 23 lanes in the bottom pic.

I’m having trouble finding actual sources right now for max rail capacity, but https://en.m.wikipedia.org/wiki/Passengers_per_hour_per_direction claims 60-90k passengers per direction on 3.5 meter lanes for “suburban rail”.

The road in the bottom picture seems to be jammed. 23 lanes are no use if there’s a bottleneck at the end.
That’s by design, and helps make the case for MOAR FREEWAY$$!
