Road Traffic Volumes

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 in 2021. Latest available data for week 48 (week beginning 29 November) show that car traffic volumes were 90.8% higher in Dublin and 104.0% higher in selected regional sites compared with week 1 of this year.

Comparing the latest available data for week 48 to the same week in 2020 shows that the traffic volume of private cars was 42.4% higher in the Dublin sites in 2021. This was to be expected as during the same week in 2020 level 5 COVID-19 restrictions were in place. However, 2021 car traffic volumes continue to remain below 2019 levels. Comparing week 48 with the same week in 2019 shows that car traffic volumes in Dublin were still 10.2% lower in 2021.

A similar trend is shown when looking at the selected regional sites. The volume of private cars in the regional locations was 42.6% higher in week 48 of 2021 than it was in week 48 of 2020. Car traffic volumes were still 14.1% lower than in week 48 of 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 and HGV traffic volumes in 2020 even exceeded 2019 volumes for the second half of the year. The latest data available (for week beginning 29 November 2021) show that HGV traffic volumes were 0.4% higher in Dublin and 5.6% lower in regional sites compared with the same week in 2020. See table 1.2, figure 1.3 and figure 1.4.
