Passenger journeys on public transport and commercial bus services have risen by 31 million since 2013, according to the National Transport Authority (NTA).
The NTA said there were 236 million journeys on public transport last year compared to 210 million in 2013.
All transport modes recorded an increase in passenger journeys with trips on Dublin Bus rising from 112 million to 125 million; Bus Éireann up three million to 32 million; Iarnród Éireann up six million to 43 million while there are now an additional three million people using the Luas to bring the annual total to 34 million.
The authority's chief executive Anne Graham said the report showed the public demand for an "efficient and reliable" public transport service.
She said it was remarkable this rise in passengers had been achieved with “virtually no increase in Public Service Obligation operating capacity as measured by seat kilometres nor in the number of licensed commercial bus operators”.
“In other words, transport operators across the State have managed to sweat their fleet assets to the greatest possible extent to provide services for the greatest possible number of people.
In 2016, Dublin Bus carried 53 per cent of all public transport users. Iarnród Éireann carried 18 per cent, Luas and Bus Éireann carried 14 per cent each, and private bus companies contracted to provide rural services carried one per cent.
Public transport services also received a 23.7 per cent increase in State funding last year, the first significant funding rise in five years.
Funding for public bus and rail services increased from €201 million in 2015 to €246 million in 2016.
The increase was in line with the recovering government exchequer figures, a National Transport Authority Spokesman (NTA) said.
The biggest recipient of increased funding was Iarnród Éireann which received an additional €35 million, a 35 per cent increase on 2015. This increase was needed because, as per EU regulations, the Iarnród Éireann business was split last year into two companies, one which deals with infrastructure and one which deals with the rail business.
Luas was the only transport operator to make a profit last year and now has cash reserves of €5.4 million. It was also the only operator to see a drop in passenger numbers in 2016 (1.6 per cent).
The authority pointed out that although Luas returned an operating surplus, “it should be remembered that all capital works such as the rail lines and the trams are funded by the exchequer.
All services experienced an increase in passenger revenue in 2016 with the Rural Transport Services seeing the biggest increase at 15.6 per cent.
Last year also saw a rise in the number of public transport vehicles on the road. Bus Éireann had 517 vehicles, up from 475 the previous year while Dublin Bus operated 967 vehicles, up from 943 in 2015.
