Abstract
The Track Geometry Interaction Map (TGIM) is proposed as an effective way to evaluate the impact of multiple track geometry parameters on rail safety. Multi-body dynamics software has been used to simulate vehicle performance over track containing a large number of randomly generated lateral and vertical track geometry combinations. A TGIM based safety threshold is generated that appears to offer both economic and safety advantages over the current FRA track safety standards.
