Broadside collision scenarios for different types of pre-crash driving patterns

Accident probabilities in broadside collisions were calculated for various types of driving patterns using the accident share for different pre-crash patterns of primary parties, as determined from macro data, and the share of the actual driving patterns of non-right-of-way drivers, as determined from observations made at uncontrolled intersections. Drivers traveling straight ahead, a pattern that accounts for a high share of broadside collisions, showed a tendency to collide with right-of-way vehicles coming from the left in the daytime. Various conceivable causes were considered, and the most probable factors coinciding with those causes were extracted.
