This approach to human reliability analysis (HRA) has been applied in the case of a safetyevaluation of the Communications-Based Train Management (CBTM) System being tested by CSXT Transportation, Inc. (CSXT).This report describes the overall approach to the HRA and itstrial application to the CBTM evaluation
