Communication-Based Train Control (CBTC) for Heavy and Light Rail Transit Systems

This project will analyze the costs and benefits of Communication-Based Train Control (CBTC) technology and determine the ability of CBTC to supplant the functionality provided by track circuits in conventional rail signaling systems. The research will evaluate current CBTC technologies; document implementation issues and lessons learned; conduct a comparative analysis of specific CBTC functional, performance, and safety requirements against industry standards; and identify needs for further research in rail transit signal and train control applications. It will address key national concerns regarding rail transit safety and productivity by evaluating the safety and reliability of CBTC technologies for both heavy rail and light rail transit systems. The project will document and analyze implementation of CBTC technologies at MTA/New York City Transit and Southeastern Pennsylvania Transportation Authority.
