Analysis of Searle, Wood and Intech Equations to Calculate Vehicle Impact Speeds in Multiple Pedestrian Collisions

In previous research, Searle, Wood and Intech pedestrian impact formulas have been validated and deemed reliable for collisions involving single pedestrians. However, little research has examined the same formulas in the context of collisions involving two or more pedestrians. This study applied Searle, Wood and Intech pedestrian impact speed equations to the throw distance of two pedestrians in a collision staged by the Victoria (Australia) Police Collision Reconstruction Unit. Using the data for pedestrian thrown furthest, each of the three pedestrian impact speed formulas reliably estimated the speed of a vehicle when it collides simultaneously with two pedestrians. Position of the head strike on the windscreen was found to be an unreliable indicator of vehicle speed in multiple pedestrian collisions. The most accurate speed estimates were produced by the Intech formula. The authors suggest that, in order to validate the results of this research, further tests should be performed on collisions involving two pedestrians simultaneously impacted.
