New figures from the Central Statistics Office show that journeys by car accounted for 73.7% of all journeys made by either as a driver or passenger last year.
The CSO figures show that walking accounted for 13.5% of all journeys and just one in 20 (4.8%) were by bus.
Nearly a quarter of journeys in 2019 were work related, while more than one fifth were for shopping, and a further one fifth of journeys were made accompanying people.
Weekdays were the busiest days for people making journeys with the average number of journeys carried out between Monday and Friday slightly higher than the average number of journeys taken at weekends.
Tuesday and Wednesday were the busiest days, the CSO noted.
The CSO said that 48.5% of people surveyed said they never use bus services while more than half (51%) never use rail (including mainline rail, DART and Luas) services, citing a lack of direct routes and services nearby.
Respondents were asked what factors would encourage them to use public transport more.
9.7% cited more direct routes, while 6% said they would like more reliable timetables. Better value and greater frequency of service, was cited by 7.1% and 6.9% of respondents respectively.
Today's figures also showed that 2.6% of over 18-year olds were involved in a road traffic collision.
Young men between the ages of 18 and 24 has the highest collision rate at 4.3% of that age cohort, while women aged 55-64 years had the lowest collision rate at 0.9% of that cohort.
Over 67% of road traffic collisions involved a car with another car, of which 69.5% were reported to An Garda Síochána and/or to their insurance company.
