Pedestrian collision analysis
Pedestrian Throw Distance Calculator
Apply the Searle method to an established pedestrian throw distance and report an upper and lower speed bound.
Why the result is a range
Pedestrian projection combines airborne motion, ground contact, tumbling, sliding, and uncertain energy transfer. The Searle method reflects this variability by producing bounds instead of a single exact speed.
Evidence to establish
- Impact location, final rest, and the measured path used as throw distance.
- Whether intermediate contacts or secondary impacts occurred.
- Surface condition, grade, and relevant drag assumptions.
- Pedestrian motion, vehicle geometry, and evidence bearing on launch conditions.
Throw distance models are screening or corroborative tools. Their applicability must be supported by the collision evidence and the model's published limitations.
