EN50556 - Road traffic signal systems Distributed and Intelligence (DPI) A Traffic control system, close coupled within a Cabinet Distributed intelligence safety data is transferred between a central control process and distributed switching. However power is still distributed from a central source and can be switched off at this point in case of emergency Distributed intelligence safety data is transferred between a central control process and distributed switching, and the switching have their own local power sources. Thus the system design and modules designs will need to ensure that the overall system can respond within members states national requirements and be proven to result in a safe state.

ring Klassisk vs. ny teknologi 6
ring Fordele ved ny signalring Ingen begrænsning på antal signalgrupper Detektorudstyr kan køre direkte over datakablet (hvis Ethernet baseret) Mindre trækrør, lettere trækning af kabler Lavvolt <50V Ingen krav til dybde af kabelrør/kabler Kan fræses ned på tværs af kørebanen 7
ring Nye muligheder ring fræset ned i rille hurtig etablering 8
