Public transport passengers are being asked to be patient and plan their journey, as capacity is to increase from Monday.
This will see capacity on buses trams and trains increase from 50% to 75%.
This means that a bus that pre-COVID could carry 80 people seated and standing, and which has been carrying 40 this week, will now be able to accommodate 60.
There may also be a few more people standing.
Anne Graham is CEO of the National Transport Authority (NTA).
She says any further easing of restrictions on services will depend on the public health situation.
"I think the Government, a few weeks ago, did indicate that they may release all restrictions on public transport at the beginning of August.
"But they would obviously take the public health advice and see what's happening, with the Delta variant in particular, to see whether it's appropriate to remove restrictions at that time".

"For this weekend, while it is good weather and we expect people to want to go to the beaches and the different hotspots around the country, unfortunately we still will have capacity of 50% to bring people to those lovely locations".
But she says there are times, specifically at weekends, when it's hard to keep to 50% capacity.
"It generally tends to be at weekends - so it's people doing leisure travel really and getting out and about as restrictions are being eased.
"That can cause some problems at times, and people may have to wait a little bit longer particularly while they're returning.
"While they might have got out to their destination with relative ease, people tend to want to travel back at the same time.
"And unfortunately we've limited capacity to be able to travel, so I think people just need to be patient and leave some time for their outward journey but also for their journey coming home".
A requirement to wear masks on all public transport services will remain in place, and people are being reminded to use hand sanitizer before and after they board.
