Simplified method for evaluating energy loss in vehicle collisions

Hierarchical Bayesian random intercept model-based cross-level interaction decomposition for truck driver injury severity investigations

“…Several studies have proposed proper indices or methods to evaluate crash impact energy. Vangi (2009) measured energy loss in vehicle crashes through damage profile linearization models. Riviere et al (2006) developed Energy Equivalent Speed (EES) to measure the impact energy a vehicle receives in a crash, and applied it to retrieving crash scene.…”

Empirical analysis of gross vehicle weight and free flow speed and consideration on its relation with differential speed limit

“…The kinetic energy to be absorbed equals one half mass multiplied by the square of velocity involved -expressing that during a crash, the amount of mechanical (kinetic) energy that must be absorbed by the impact is greater at a higher speed and mass. Further details about the energy loss in damage due to vehicles in road accidents can be found in Vangi (2009), Wood and Simms (2002) and Wood (1997).…”

Answer to the letter to the editor by R.M. Brach “Comments on energy loss in vehicle to vehicle impact by Dario Vangi”

“…Considering the importance of energy loss evaluation, lately Vangi has defined a further simplification of the CRASH3 method to evaluate the energy loss, by linearizing the profile of the damage [3] and obtaining a very easily and powerful method.…”
