Traffic Count Data

Road Traffic Volumes

Source: Transport Infrastructure Ireland

Following the re-introduction of Level 5 restrictions on 27 December 2020, car traffic volumes dropped significantly at the beginning of this year. However, in line with the gradual lifting of travel restrictions car traffic volumes increased throughout 2021. Data just before Christmas (week beginning 13 December 2021) show that car traffic volumes in Dublin nearly doubled compared with week 1 of this year. Data for that week also show that the volumes of private cars were 8.7% lower in Dublin and 8.5% lower in regional sites compared with the same week in 2019. See table 1.1, figure 1.1 and figure 1.2.

The impact on HGV traffic of COVID-19 restrictions has not been as pronounced as for cars. HGV traffic volumes in 2021 exceeded 2019 volumes for most of the second half of the year. However, weekly data for December show that 2021 HGV traffic volumes remained below 2020 levels and towards the end of the year also below 2019 levels. Please note that the weekly comparisons of HGV volumes were affected by the timing of Christmas. See table 1.2, figure 1.3 and figure 1.4.
