Collision analysis between road vehicle and train at level crossing

Abstract

This paper deals with analysis (modeling) of collision between road vehicle and train at level crossing. Collision analysis is used in forensic engineering for the assessment of traffic accidents. Several methods can be used for the theoretical analysis of vehicle motion at and near the level crossing. In this work the time interval method is applied. Based on the theoretical analysis of vehicles motion, a parametric theoretical computational model was developed to simulate three possible scenarios. The road vehicle approaches the level crossing either with uniformly decelerated motion, or with constant velocity, or with uniformly accelerated motion starting from zero initial velocity. The rail vehicle is always moving with uniformly decelerated motion. The model was created using free mathematical software SMathStudio.
