摘要：
The effects of geometric design and traffic characteristics on accidents on two-lane rural roads with a moderate average daily traffic (ADT) between 400 and 3000 vehicles per day were studied for two data sets. Geometric design elements were aggregated into 'bundles', or groups frequently found together in the field as a result of design policies. Advanced multivariate analysis techniques were used to explore their relationships with accident experience. It was found that accidents interact in such a complex way with ADT that the rate of accidents per mile-year is superior to the conventional rate of accidents per vehicle-mile for models developed from typical accident data files.
