Public transport providers have appealed to the public not to use public transport unless it is necessary and to avoid it at peak times in the morning and evening if possible.
Capacity has been increased to 50% to cope with the additional demand.
General Secretary of the National Bus and Rail Union Dermot O'Leary said his members are concerned about the increased capacity on public transport, and is seeking clarity as to whether this includes both standing and seated passengers.
Speaking on RTÉ's Today with Claire Byrne, he said it is not the job of bus drivers to police capacity, but said he is concerned that they will do their best to carry people, and "by doing that they're not only putting themselves under pressure, but putting the commuters under pressure".
Mr O'Leary said if passengers are told there are only 32 or 33 seats and the rest have to stand "people may not be inclined to stand if they see vacant seats, there's the potential for the middle doors to be blocked".
Taoiseach rejects suggestions that Govt took 'serious gamble'
Taoiseach Micheál Martin has rejected suggestions from Solidarity/PBP TD Richard Boyd Barrett that the Government took a "serious gamble" by reopening the hospitality sector.
Mr Boyd Barrett said the move risked family gatherings at Christmas time.
Mr Martin said the Government did not reject the advice of the National Public Health Emergency Team, adding: "we did not open wet pubs because of tracking what happened in August and September."
"We took a more conservative approach on the household visits.
"There is only so much a Government can do in a democratic society", he said.
"We took a balanced measured approach".
Meanwhile, Infectious Diseases Consultant at St James Hospital Dr Cliona Ní Cheallaigh said there is no downside to improving ventilation and it has a big effect in reducing the risk of Covid-19 transmission.
Speaking on RTÉ's Today with Claire Byrne, she said she opens windows on buses and in offices.
Dr Ní Cheallaigh said it would appear that shops are managing the numbers well and people are adhering to public health advice.
She said people who want to mix with vulnerable people over the Christmas period should make every effort to minimise their social contacts now.
