Sometimes there are so many people in the morning that ground transport abruptly goes into hibernation, as if.
I understand that the interval is so small during peak hours, but this flow needs to be unloaded, somehow by land transport.
If we talk about the subway, then the subway is like a subway
And as such, there is no bus station here because of the gathering of taxi drivers and public transport, there are eternal congestion and traffic jams, especially in winter.
The advantages are that there is a place to shop, exchange currency, eat, get a haircut and much more.
