FRA sponsors ongoing research on passenger rail equipment occupant protection at the Volpe Center. The Volpe Center contracted Calspan to conduct pendulum impact testing of the THOR-50M ATD. A series of 28 pendulum impact tests was performed on the lower chest and abdomen of the THOR-50M to...
Researchers studied the effectiveness of an integrated laser-triggered queue detection system/light-emitting-diode (LED)-enhanced “DO NOT STOP ON TRACKS” sign as compared to a baseline version with no lights. Testing was conducted at the Jay Street grade crossing on the Metro-North Railroad in...
Phase II of the Track Database Auditing System (TDAS) program sought to produce a system development and implementation plan with a more comprehensive outline of the project approach and goals, as well as further refine the Concept of Operations (ConOps) and system requirements developed in the...
The work conducted by TTCI took place under this Phase II research. The appendices includes the following: the System Development and Implementation Plan; the revised Concept of Operations (ConOps) document from Phase I; an updated System Requirements Specification document from Phase I; the...
The Federal Railroad Administration wants to better understand driver knowledge of and expectations for finding Emergency Notification System (ENS) signs at highway-rail grade crossings. A simulator study was designed where participants were exposed to ENS signs of different orientations (...
In February 2016, the Federal Railroad Administration’s (FRA) Office of Railroad Safety (RRS) and Office of Research, Development and Technology (RD&T) established a multi-phase research program to better understand vertical split rims and other wheel failure modes with a focus on failure...
This study includes a review of European Union (EU), US and Asian standards, codes, and regulations related to high speed rail. Key results include: 1) a detailed survey performed on the topics of global standards and regulations for transportation noise with a focus on high speed rail...
Transportation Technology Center, Inc. conducted an impact test with two F40 locomotives to evaluate the performance of both vehicles under dynamic conditions. One locomotive was retrofitted with crash energy management (CEM) components including a push-back coupler (PBC), deformable anti-...
Transportation Technology Center, Inc. conducted impact tests with a Budd M1 passenger car and an F40 locomotive to evaluate the performance of both vehicles under dynamic conditions. The locomotive was retrofitted with crash energy management components, including a push-back coupler (PBC) and...
Researchers at Michigan Technological University used Second Strategic Highway Research Program (SHRP2) naturalistic driving study (NDS) data and a driving simulator to perform a quantitative evaluation of driver behavior at highway-rail grade crossings (HRGCs). They developed a 3-point scale to...
