This animation demonstrates a pedestrian v. vehicle collision that occurred when the vehicle continued driving through a red light. An engineering analysis was conducted by DJS Collision Reconstruction and Biomechanical Engineers. An accurate, to scale 3D engineering animation was created as a demonstrative for trial. The result shows a pedestrian vault, which is a movement similar to that of a football being punted. This movement involves many factors, including vehicle speed, angle of impact, ground coefficient of friction, vehicle point of rest (if they stop), and the pedestrian point of rest. These factors can be used to calculate the vehicle speed at the time of impact.
