Poor transit ride quality may not be an indicator of unsafe operation but may point to a vehicle or to an area of track that needs maintenance to prevent further geometry degradation.
TCRP Web-Only Document 76: Performance-Based Track Geometry, Phase 3, from TRB's Transit Cooperative Research Program, helps to develop methods to identify track conditions and locations that cause poor ride quality or vehicle performance.
Supplemental to the report is a Presentation.
