摘要

The accident history of two urban routes, each of approximately 40 km in length, has been examined. The routes included roads of all categories, from motorway to back streets and some 2,700 injury-accidents occurred on the routes during the 62 month period analyzed. Statistical relationships were determined between various measures of accident-rates and road or traffic variables. Those factors that were found to be significantly related to accidents were used as criteria by which to disaggregate the accident data into categories for which multiple regression equations could then be formulated as a basis for predicting accident-rates.
