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 (...
