It's not necessarily important for every private hire vehicle to

That I understand

but unless that "minimum number" is somewhat larger than you
might first calculate, you either end up with the accessible cabs
waiting around all day for the one disabled passenger, or no
accessible cabs free at the time that passenger turns up.

It's queuing theory 101, not that difficult.

to a graduate level statistician perhaps,

You do Stats 101 in the first year!

In the first year of what?

The undergraduate course. I can't believe you really didn't know that.

your post was unclear.

I really didn't know what it was you were saying (you could have meant
"first year at school", for all I knew).

"[Name of Subject] 101" is a well-known way of describing first year
("freshman") courses at university.

It stems from American universities, but it has been in use in the UK
by (at least) the Open University since 1977.

It is fairly well understood in the UK, I'd say.
