THE CAUSES OF ROAD COLLISIONS: A REPORT BASED ON SAMPLINGS IN ONTARIO

This paper reports on the analysis of data gathered in field investigations of Ontario traffic collisions and identifies the causes of more than 90% of them. The data base consists of 97 traffic collisions, though findings are based on 89 collisions. Both city and rural areas were investigated. Substandard pedestrian behavior was the cause of two of the collisions. Direct driver causes constituted 93% of the collisions: 22% and 18% of these collisions, respectively. Substandard vehicle condition was a definite cause of 9% of the collisions, and may have been a cause in another 9%. Substandard road condition was a cause of 9 of the collisions. Causes investigations would provide wide and local significance categories of useful statistics. The costs of causes investigations will depend upon the organization devised for the program. A media campaign to educate drivers, first concerning the hazards of the shoulder-to-pavement manoeuvre, and, second, the technique necessary to accomplish the manoeuvre successfully, is suggested. /MW/
