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 .

Command-level decision making is a critical factor in successfully managing and mitigating critical incidents. The TRB Transit Cooperative Research Program's TCRP Web-Only Document 75: Command-Level Decision Making for Transportation Emergency Managers is a document done in collaboration with TRB's National Cooperative Highway Research Program (NCHRP) and Airport Cooperative Research Program (ACRP). The work is designed to assist public transportation agencies, state departments of transportation (DOTs),...

The TRB Transit Cooperative Research Program's TCRP Web-Only Document 74: Recent Decline in Public Transportation Ridership: Hypotheses, Methodologies, and Detailed City-by-City Results provides supplemental information to TCRP Research Report 231: Recent Decline in Public Transportation Ridership: Analysis, Causes, and Responses , which delves into exploring ridership losses already being experienced by transit systems prior to the COVID-19 pandemic.

Joint development is a subset of transit‐oriented development. It consists of residential, commercial, civic, or mixed‐use development that is closely coordinated with a transit facility and in which the transit agency participates through the use of its property, funding, or some other form of real estate or business transaction. The TRB Transit Cooperative Research Program's TCRP Web-Only Document 73: Guide to Joint Development for Public Transportation Agencies: Appendices provides supplemental inform...

There are three major perspectives on transit reliability: from the customer, agency, and operator points of view. The TRB Transit Cooperative Research Program's TCRP Web-Only Document 72: Developing a Guide to Bus Transit Service Reliability finds, through a transit agency survey, that most agencies do not have a formal bus service reliability improvement program. The guidebook presents a framework for such a program, including eight steps, and is a supplemental report to TCRP Research Report 215: Minut...

TRB's Transit Cooperative Research Program (TCRP) Web-Only Document 71: A Transit Agency Guide to Evaluating Secondary Train Detection/Protection Systems in Communications-Based Train Control Systems provides a practical approach to evaluating the appropriate level of secondary train detection/protection systems (STD/PS) for a given communications-based train control system application. In terms of detection, track circuits and axle counters are both considered and compared, including the broken rail det...
