Abstract
Dette projekt undersøger, om Danmarks mangeårige nationale signalsystem kan sammenlignes meningsfuldt med det nye European Rail Traffic Management System (ERTMS), som er ved at blive indført. Begge systemer beskrives, hvorefter deres funktioner, potentielle farer og sikkerhedsbarrierer analyseres (tekniske og proceduremæssige tiltag, der forebygger eller begrænser ulykker). Farer blev identificeret efter Common Safety Method (CSM) og registreret i en Hazard Log (en struktureret liste over risici). Fault Tree Analysis (FTA) blev brugt til at sammenligne, hvordan hvert system klarer sig i tilsvarende farlige situationer. Undersøgelsen konkluderer, at systemerne kan sammenlignes, og at begge er sikre at drive ud fra kriterierne i CSM og Safety Directive. De adskiller sig dog i deres funktioner, i hvilke farer der opstår, og i hvilke sikkerhedsbarrierer de anvender.
This project asks whether Denmark's long-used national rail signalling can be meaningfully compared with the new European Rail Traffic Management System (ERTMS) now being rolled out. It describes both systems, then examines their functions, potential hazards, and safety barriers (technical and procedural measures that prevent or limit accidents. Hazards were identified using the Common Safety Method (CSM) and recorded in a Hazard Log (a structured list of risks). Fault Tree Analysis (FTA) was applied to compare how each system performs in similar hazardous scenarios. The study concludes that the two systems can be compared and that both are safe to operate under the criteria of the CSM and the Safety Directive. However, they differ in their functions, the types of hazards they present, and the safety barriers they rely on.
