STRATEGIES FOR SAFETY PROBLEMS - SITE CLUSTERING OF ACCIDENT TYPES ON ROAD CLASSES. NEW ZEALAND ROADING SYMPOSIUM 1987. VOLUME 3

The examination of the site "clustering" of specific accident types can lead to the recognition of a class of site specific problems which by the appropriate treatment of relatively few locations can lead to a sizeable overall reduction of that accident type. This paper examines the site "clustering" or "non-clustering" of particular accident types on four functional classes of road in metro Melbourne using the 1981 accident data. The frequency of accidents at intersections and links showed that the accident type rum (20-29) "vehicles from two streets" was the predominant accident on all four road classes and exhibited clustering on the three higher classes. Accident type rum 31 "right turn against" was a high frequency type on primary and secondary arterials and also exhibited clustering on these two classes. The accident type rum (37,33,35) "rear end" while being a high frequency type on the top three classes exhibited clustering only on primary arterials. The number of sites with clusters of rum (20-29) varied as primary 104, secondary 95, and collector 35. For rum 31, the number of sites varied as primary 111 and secondary 25. The high frequency accident types on links did not exhibit any site clustering. For the covering abstract of the symposium see IRRD 810782. (Author/TRRL)
