FACTORS AFFECTING CRASHES AT SIGNALISED INTERSECTIONS

This report presents the results of a study of signalised intersections in Melbourne, focussing on the differences in site and operational characteristics between sites with a "high", "normal" and "low" accident frequency over the 5 years 1987-91, based upon an analysis of accident data and entering traffic volumes. The study indicated that the majority of the variation in accidents was not explained by traffic volumes, but by other factors. While no single factor was identified which would lead to a dramatic improvement in safety at signalised intersections, a range of measures were identified which would likely contribute to improved safety if applied at specific sites where relevant.
