The available data bases for accidents, road geometry (photolog output) and traffic counts were combined and the accident rates determined for two lane, four lane and six lane road categories as well as for 22 geometric element categories. An analysis of the road kilometre distances reported for accidents was also undertaken. For some sections of road, the recording of accidents was over represented at the whole and half kilometre distance points and for other sections bridge points were over represented. The accident rates calculated for geometric elements plotted against traffic volumes gave poor correlation coefficients for linear trends. Recommendations are made for more accurate accident distance reporting.
