Passenger numbers on public transport are "down significantly" compared with this time last year, according to the National Transport Authority.
However the NTA says that, in the vast majority of cases, services provided by Iarnród Éireann, Dublin Bus, Bus Éireann, Go-Ahead Ireland, Luas and Local Link will continue to operate as normal throughout the country.
Preliminary figures suggest daily passenger numbers have fallen to between 25% and 30% of the equivalent levels in 2019, according to preliminary figures.
The NTA says it will continue to monitor transport patterns, in conjunction with the operators.
Each public transport operator has also established an internal coordination group, which is meeting daily to monitor developments around COVID-19 and continually update existing contingency plans.
The NTA also says that all customer service channels "remain open and are being monitored" by staff.
