Findings

Model verified with literature data

Good agreement with numerical simulations

Simplifies collision analysis process

Abstract

This paper discusses a simple theoretical throw model for frontal vehicle-pedestrian collisions. The model is based on the simple assumption that pedestrian movement after impact can be approximated by movement of a mass point. Two methods of reconstruction of vehicle-pedestrian collision are discussed: one knowing only the throw distance and the other when also impact to ground contact distance is known. The model is verified by field data available in the literature and by comportment with full scale numerical simulation. This paper has been withdrawn by the author due to error in spreadsheet program which results in misleading results in verification section of the article.
