A MODEL OF SEASONALLY CORRECTED INDICATORS OF ROAD SAFETY

The daily series of the number of accidents and victims on the road in France from 1985 to 1992 have been broken down into three additive components: a short-term meteorological effect, a calendar effect and a residual series corrected for these two effects. The double adjustment for the short-term meteorological effect and the calendar effect represents a local correction, appropriate to the varying context of road safety. The data thus corrected for local effects are then aggregated on a monthly basis, and seasonally corrected by a standard method, applied by means of the Census-XII program. The final seasonally corrected values results from a local adjustment, within each month, followed by a monthly correction applied over the year. The detailed daily results on the number of fatalities in France apply to the second 4-month period of 1992, which saw the introduction effective from July 1992 of a new "point" system against drivers at fault. Detailed monthly results cover the whole period modelled from 1985 to 1992.
