Transit agencies around the country are facing the challenges of reducing transit bus collisions and the injuries, fatalities, and liability expenses associated with these collisions. The TRB Transit Cooperative Research Program’s TCRP Synthesis 145: Current Practices in the Use of Onboard Technologies to Avoid Transit Bus Incidents and Accidents documents the current practices in the.. read more →

This report is about a comprehensive study that includes background research and analysis on needs and gaps for voluntary standards or recommended practices for crashworthiness and crash energy management (CEM) for less than 30-ft paratransit body-on-chassis buses (cutaways).

This report includes an examination of the standards, guidelines, and recommendations associated with crashworthiness and Crash Energy Management (CEM) for transit buses, including articulated buses, BRT buses, and paratransit body-on-chassis buses.  View Report read more →

The objective of this research is to develop a process for (1) conducting systemic safety analyses for pedestrians using analytical techniques to identify pedestrian activities (including behavior), roadway features, and other contextual risk factors, e.g., land use, that are associated with pedestrian crashes; (2) identifying appropriate and cost-effective systemic pedestrian safety improvements to address their.. read more →

This report summarizes the data findings from profiling 17 Florida transit agencies in regards to rear-ended and side collisions. Site visits were conducted to get a better understanding of their procedures for investigating, tracking, and preventing collisions. It also included an analysis of their NTD and non-NTD collision data. Based on the findings, this report.. read more →

The NTSB conducts thorough investigations (including root-cause analyses) of events – not simply stopping with the obvious. Presentation | Abstract read more →

This safety report focuses on commercial vehicle onboard video systems as they relate to the evaluation of both driver and passenger behaviors and collision analysis.  View Report read more →

The Most Wanted List represents the NTSB’s advocacy priorities. It is designed to increase awareness of, and support for, the most critical changes needed to reduce transportation accidents and save lives. View Most Wanted List read more →

This report presents methods and research activities that informed the development of TCRP Report 175. The key research activity was visiting several public transit rail services crossings within select regions. These visits provided the opportunity to observe the challenges faced by pedestrians at public transit rail services crossings and included observations made during three site.. read more →

This investigation examined the feasibility of using composite metal foams (CMF) to improve the crashworthiness of rail passenger cars. Metal foams integrated into the structure of passenger cars have the potential to significantly increase crash energy absorption. This would provide additional protection to occupants in collisions or derailments.  View Report read more →
