Rail system simulation for risk assessment, safety and operational analyses
A tool that simulates train movements with abilities to predict hazards and unsafe conditions, to facilitate risk assessment, safety and operational analyses.
Risk assessment with high degree of confidence
A principal challenge in introducing new railroad traffic control technology, like positive train control (PTC), is to demonstrate convincingly that safety will not be compromised. The Federal Railroad Administration (FRA) has established guidelines for submitting a performance-based Product Safety Plan (PSP), which is to include a risk assessment of potential accident scenarios. GTMS was developed for the FRA.
A key risk driver is the frequency with which events occur that may be precursors to hazardous situations leading to accidents. Such events may be the intersection of a train with a device or certain situations of train-to-train proximity. Reliable probability estimates of these events, or “exposure metrics”, can be derived through the simulation of a rail system, which realistically replicates both train movements and the system of traffic control.
Hazards, collisions and derailments are rare events whose probabilities of occurrence can be predicted through advanced simulation methods. GTMS is a proven tool that achieves this requirement.
