Application of the Monte Carlo Method and Complex Cross-Ratio in Traffic Accident Reconstruction


Abstract

This study presents an approach to estimate speeds in forensic traffic accident analyses, combining the Monte Carlo method with photogrammetric estimates based on complex cross-ratio. For practical application, a new software was developed in the R programming language using the Shiny library, providing an interactive web interface. The methodology was tested in a case study involving a scaled-down vehicle, where the estimated speeds were compared to those obtained with the Amped Five software, a market reference that uses two-dimensional photogrammetry. Statistical analysis, conducted with the Wilcoxon test, did not detect significant differences between the methods (p > 5%), thereby suggesting the methodology as a viable alternative for forensic investigations.
