своя очередь; до

Hi!

I read this sentence on the Internet -> В настоящее время в порту "Кавказ" своей очереди на паром ожидают до 1010 автомобилей.

I don't quite understand the underlined words.

I know only "в свою очередь" phrase meaning "as for me".

I think that "до" mean "up to" but I am not sure at all.

waiting for their turn

That's correct. But it sounds awkward in that sentence. They can't say exact number of cars in the queue, but give "too exact" estimate.
More appropriate examples of use for "до":
Завтра днём ожидается до +25 градусов.
Диспетчер может вести одновременно до 10 самолётов.
Пропускная способность нового моста - до 1000 автомобилей в сутки.

своей очереди - waiting for their turn,

до - here 'up to', better to say До 1000 - up to 1000, implies that it's the approximate number.

I second the point about the "up to 1010". It's like "We bought nearly 316 bottles of Jack Daniels for the party"
