Broken Rail and Rollout Detection to Support QMB Operations
Transportation Technology Center, Inc. (TTCI) collaborated with a railroad advisory group to progress a track circuit concept that supports the Quasi-Moving Block (QMB) method of train control. TTCI performed proof-of-concept testing, capacity analysis, hazard analysis, and requirements...
Enhanced Automatic Train Control Braking Algorithm Research and Development
The primary objective of the project was the evaluation of the braking enforcement methodology used by the railroads that have implemented an E-ATC PTC system. The methodology developed under this project can be used by the industry to verify that the braking enforcement algorithms meet...
Machine Vision Data Products for the Automated Track Inspection Program
The Federal Railroad Administration (FRA) Office of Railroad Safety’s Automated Track Inspection Program (ATIP) uses machine vision inspection technology along with Track Geometry Measurement and Gage Restraint Measurement Systems to thoroughly evaluate track. Algorithms trained to detect...
Railroad Information Sharing Environment (RISE)
Despite tremendous progress in railroad safety over the last 30 years, many safety statistics have plateaued. Thus, additional insights on the complex interaction between people, trains, infrastructure, and the operating environment are needed. While the Federal Railroad Administration (FRA)...
Lessons from the Railroad Information Sharing Environment (RISE) Pilot Project
This research documents lessons learned from the development of the Railroad Information Sharing Environment (RISE), a voluntary partnership for sharing safety sensitive information among multiple railroad industry stakeholders for the purpose of identifying, evaluating, and managing safety...
