The volume of traffic increased in the run up to Christmas but has since declined sharply, according to the latest Transport Bulletin from the Central Statistics Office.
The bulletin notes that heavy goods vehicle (HGVs) traffic, in particular, rose from the start of December and was 33.1% higher in Dublin in the week of December 20 compared to the same week in 2019.
HGV traffic was also 34.5% higher in the rest of the country. But car volumes were lower by 45.5% in the week beginning December 27 in Dublin and 45.1% in the rest of the country compared to the same week in 2019.
This followed the reimposition of Level 5 Covid-19 restrictions. Air travel continues to be worst affected by the outbreak of Covid-19.
