Abstract
This brief report deals with predictions of road traffic accidents for each month of the year. Two models were used for predicting injury and material damage and fatal accidents. For injury and material damage accidents, the predicted value for any month depends on the value twelve months earlier, as well as on the value in the previous month. For fatal accidents, the predicted value for a month depends only on the value the previous year, indicating much less variability in fatal accidents as evidenced also by the fact that 600 people have been killed on Irish roads each year for the last ten years.
