A pedestrian impact invariably results in serious injuries to the pedestrian and questions arise as to the movements of both the vehicle and the pedestrian in the seconds leading up to impact. Using evidence gathered from the vehicle and the accident site, we can analyse aspects of the impact such as vehicle speed, pedestrian path, and visibility. Pedestrian walking or running speeds, combined with the geometry of the accident scene, can be used to assess whether the driver had any opportunity to avoid the impact.
