Abstract

This report presents the results of a study to analyze potential crash scenarios for various light rail vehicle designs and apply the results to develop crash energy management guidelines. The crash scenarios involve both collisions between light rail vehicles of identical or dissimilar design and collisions between light rail vehicles and highway vehicles. The analyses were performed using detailed nonlinear dynamic finite element simulations of the collisions between the various vehicle types. Collision responses such as the crash force levels and crush lengths in the colliding light rail vehicles or the maximum crush in the struck highway vehicles were determined and can be used to define crash energy management requirements in a light rail safety standard.
