A Free access tool based on a pedestrian-vehicle collision model is presented. The model permitted the qualitative and quantitative description of the events whole dynamic by segments called pre-collision, collision, and post collision. Furthermore, it enabled the determination of the magnitude of the vehicles initial speed before the collision with a pedestrian and the location of the point position of impact on the road where the accident occurred. The models inputs are related to the evidence collected at the scene, which provides a checklist platform for supporting investigators fieldwork. Additionally, the pre-collision segment permitted the investigators to develop an avoidability study that may contribute to road safety evaluation. The model was validated, comparing the results statistically with experimental cases developed with dummies, bodies, and reconstructed cases. It is shown that there is no significant difference, thus verifying its functionality. The tool is available as a mobile app in Spanish and English, allowing significant affordability to investigators from some low and middle-income countries., Comment: 2 figures, 23 pages (20 main document and 3 for Appendix)
