Pedestrian numbers in Dublin city centre have shown a "marked decrease" since Level 3 restrictions came into force, according to the city council.
The latest mobility report found footfall in the core city centre area between St Stephen's Green on the southside and Henry Street on the northside had reached 60% of pre-Covid-19 levels, prior to the latest restrictions.
But they have now fallen again.
Footfall had been recovering in Henry Street and Grafton Street but since Level 3 restrictions there has been a "sharp drop" in Henry Street, according to the mobility report.
However, Grafton Street has not suffered a similar reduction in pedestrian numbers and an evaluation is being carried out into the trial pedestrianisation of streets around the popular shopping district.
Contactless pedestrian buttons are also being rolled out across the capital following a successful pilot.
Commuter pedestrian counts at canal cordon count locations carried out between May and July showed levels at only 20% compared to normal.
This increased in the first week of September - but only to 35% of what would be expected at this time of year.
