Eight in 10 fatal collisions occur on rural roads.
New research by the RSA, which looked at the period between January and mid July, has found that 12 noon to 4pm is the riskiest time.
65 road deaths occurred during this time period, 11 of which were in Dublin.
There were two fatalities in Donegal, 1 in Sligo, none in Leitrim and 4 in Cavan.
Chief Supt Michael Hennebry from the National Roads Policing Bureau says Gardaí will focus on policing more rural areas.
