Performance-based track geometry inspection: What it is and how it works

摘要

TTCI begins implementation of a new track inspection technology that relates track geometry to vehicle performance, resulting in better safety and maintenance actions. Anew "add-on" technology has been developed to relate measured track geometry to vehicle performance on a real-time basis. The technology can also be used on historic track geometry data to examine the effect of track geometry degradation on vehicle performance. Following several years of research and development, the Transportation Technology Center, Inc., Pueblo, Colo., has started the demonstration and implementation of its performance-based track geometry, PBTG, inspection system.1 The PBTG inspection system is a new add-on technology that can be implemented on conventional track geometry inspection vehicles.
