Figures from the Central Statistics Office show that journeys by rail and bus remain 57% lower than pre Covid-19 levels but that the volume of cars is returning to pre-pandemic levels.
The CSO said that as Covid-19 restrictions ease, car traffic volumes for the week ending 8 August were just 12.6% lower than 2019 levels at regional locations and 16.3% lower in Dublin.
HGV traffic volumes are exceeding 2019 levels for the seventh week in a row, while the volume of HGVs measured at selected sites in Dublin from 21 June to 8 August exceeds that measured for the same time in 2019 by 3.9%.
The CSO noted that public transport volumes are recovering at a much slower rate than road traffic, adding that the impact of Covid restrictions on rail journeys was more significant than that on journeys by bus or Luas.
It also said that data from Irish airports shows that air transport continues to be heavily impacted by Covid-19 restrictions.
The number of passengers travelling through Dublin, Cork and Shannon airports in the first seven months of 2020 is 70.3% lower than the same time last year.
The total number of passengers handled by those airports in July fell from 3,911,133 to 416,436 - a drop of 89.4% - the CSO added.
